Bearing 6005 dimensions. Materials for the production of fundamental elements

General information about ball bearing

The manufacture of 6005 ball bearings is very large number organizations: GPZ-34 LLC, Instrument Bearing Plant JSC, Tashkent Bearing Plant-33, Alma-Ata RPZ, Kuznetsk Roller Plant OJSC, OK-LOZA OJSC.

The separator serves to separate the rolling elements from each other, promoting an increase in the rotation speed of the ball bearing. The bearing cage can be stamped, machined or polymer. Parts of a ball bearing: cage, outer race, small ring and ball.

The primary features that characterize bearing 6005 are:

installation diameter (Dmax, 47 mm): outer ring diameter
mass (M, kg): one or a thousand pieces - mainly used in design for calculation total mass of the designed machine
internal diameter (d) equal to 25 mm: diameter of the inner ring - corresponds to the diameter of the mechanism spindle neck
Clip width (H) (inner (B) and outer (T)): almost always combined into one parameter, if they coincide

Application range of 6005 ball bearings (best for such applications):

small shaft journal diameters
not very heavy operating loads
technical defects in the form of misalignment
loads perpendicular to the shaft
high shaft speed

Manufactured according to: GOST 1 8338-75 (ST SEV 3795-82), ETU 100, ISO 8443-86, GOST 520-2011, ST SEV 6427-88), TU 37.006.153-89, GOST 10058-90 (ISO 1224) -84.

The main disadvantage is poor resistance to loads. Key advantages: the rolling resistance of the balls does not depend on the rotation speed and the applied load and can be 0.0005 - 0.001 cm, wide applicability, wide product range, very high precision, noiselessness, rotation speed, low runout.

The photopolymer separator is made from PEEK, polyamide-6, textolite. The stamped separator is produced from steel with a reduced percentage of carbon (C) in accordance with NTD EN10111:2000. The machined cage is made from S355 structural steel in accordance with ISO 10025:2004 or CW612N brass in accordance with ND EN1652:1998.

Material grade of metal balls: ШХ15-В; ultra-pure through-hardened chromium-carbon steel (1.3505 according to EN 683-17); NitroMax steel. Steel balls are produced in accordance with GOST 3722-2014. Ceramic balls are made from silicon tetranitrogen in accordance with ISO 26602-2017. The rolling body (ball) may have heat treatment to hardness: from sixty to sixty-five Rockwell units.

The difference from other types of bearings is that the balls run along the grooves of the outer and inner rings

Ball bearing 6005 belongs to the category of rolling bearings. The most common type. A ball bearing can effectively counteract the displacement of the working shaft in the direction perpendicular to rotation and is weakly effective in the axial direction. Operating principle: movement of spherical rolling elements in the grooves of the rings. One of the most popular bearing types. Type of moving body: sphere.

Radial bearing 6005

Materials for the production of fundamental elements

The shape is balls with a perfectly flat working plane. To achieve the greatest effect and in order to achieve resistance to rust, they are additionally sprayed with chromium or nickel. Before cladding the coating, the balls are additionally treated thermally, which can make it possible to obtain the greatest rigidity.

In the current decade, exclusively composite substances are taken as the basis for production. In addition, the following are vigorously applied:

Aluminum compound - Al2O3
Si3N4
Silicon carbide SiC

All such connections are guaranteed to withstand corrosion and are able to resist temperature influences: from -170 0C to +1000 degrees Celsius.

It is worth saying that the longitudinal load is taken by it much worse. This type of bearing gets its name due to its ability to withstand radial forces.

The main components of the 6005 radial bearing mechanism also include 2 rings with diameters of 25x47 mm, in the body of each of which a bed for the balls is made. These balls, inserted between two sleeves, have a precisely adjusted distance between them. Controls the distance of the separator or cage. It is a ready-made mechanism, the main components of which are considered to be rolling bodies (in this case, a ball).

GOST standards

All radial ball bearings of this type are manufactured strictly in accordance with the standards adopted at the state level and meet GOST R 52545.2-2012.

Labeling Standards

Marking 6005 is deciphered from the right side to the left:

Internal diametric designation, which is conventional - 2 characters
Basic product type or model - one character
Caliber group - one digit
Design type - two digits
Scale series - one symbol

In strict accordance with the parameters of the domestic designation, the designation of these bearings is typed by GOST 3189-89 (Ball and roller bearings) and necessarily contains the code of the plant where they were manufactured. The final result, the marking consists of:

The first 7 numbers are the main marker (in some cases this is just a pair of numbers, when the composition of the features is zero)
If on the right side, then one or another letter is indicated first. In cases where auxiliary values are to the left, they are necessarily preceded by a hyphen (-). Additional letter or numerical designations, which can be located both to the left and to the right of the main one

Scope of application

A rotating part is a necessary part of almost every device:

Drum
car wheel
Rotating cylinder

The role of the ball bearing in the production of structural devices can hardly be overestimated. It is important to realize that a properly replaced radial ball bearing can extend the life of the entire device.

In order to increase the speed properties of parts, this type of radial ball bearing is constantly used in:

Axial devices
Centripetal device
Worm gearbox

The following mechanisms cannot do without a radial rolling bearing:

Metallurgical
Energy
Mining

The function of the 6005 deep groove ball bearing determines the design of its balls:

With a deterministic tolerance, if we are talking about a heat-resistant bearing. This is done to avoid the ball jamming when the temperature rises.
Tightly installed balls (the last one is driven in with force). Mainly, this type of structure is used for assembling automobile bearings

Bearing 6005 is a single-row radial ball bearing with dimensions 25x47x12.

Direction of impact received of this element– two-way radial and axial. Moreover, the second is up to 70% of the unused permitted radial load.

The bearing is capable of operating under axial force at very high rotational speeds.

The designation 6005 is the international name format. In Russia it can be found under number 105.

The open type of the product has a higher maximum rotation speed, and it is better to use liquid mineral oil as its lubricant.

The product is made from chrome, carbon and stainless steel.

Standards and technical specifications for the original product and its transmodifications: GOST 520-2002, GOST 520-2011, ISO 9001.

The design is possible both open (101) and closed - on both sides (80105), closed on both sides (180105 - double-sided seal made of plastic or rubber). Lubricant is added to closed configurations during production, and the part is completely protected from moisture and dust. Does not require auxiliary care.

Bearing 6005 dimensions and technical specifications has the following: inner diameter - 25 mm, outer diameter - 47 mm, height 12 mm, weight 0.064 kg, number of balls - 10 pcs., nominal rotation speed - 18000 rpm.

Additional designations of foreign parts with design characteristics: 6005 RS, 6005 Z, 6005 ZZ, 6005 2RS, 6005 ZN, 6005 N, 6005 2ZN, 6005C3, 6005 2RSN. Marking of modifications according to ISO (bearing 6005 GOST) for foreign prototypes: NSK 6005, FAG 6005, SKF 6005, FBJ 6005, INA 6005, KOYO 6005, NTN 6005.

Special markings 2RS, ZZ, Z indicate the presence of protective seals and washers. They are produced by SKF, FAG, NSK, IBC, FBJ, ISB, LSA, NKE, ZKL. The price of foreign production is more expensive than the price of domestic production.

The table shows the parameters of a 6005 radial ball bearing, closed with “rubber” plugs, into which plastic lubricant has been added in advance (the applicability of this is higher); for an open product lubricated with liquid mineral oil, the maximum rotation speed will be higher. See below for more information about various modifications.

Like any small-sized single-row radial ball bearing, this type can be open (no additional designations) or closed. In this case, there are additional symbols to the right of the number:

ZZ or 2Z - metal washers (straps) on both sides;

2RS, 2RSH, 2RS1, 2RSR, DD, UU, LLU, 2NSE9 (depending on the manufacturer) - double-sided rubber seal reinforced with sheet steel (“rubber”). The groove for fastening the retaining ring is indicated in the number by the letter N. Larger bearings with the indicated indices They are no different from each other, have similar characteristics and can often be interchanged. Single-sided imported bearings are not very common and are rarely on sale; the extension will be RS or Z by analogy.

An important feature of rolling bearings is the radial clearance group. If C3 or C4 is indicated, the gap is increased (“weakened”), such modifications are used in units with high temperature(the gap is needed because the steel expands and friction increases). If your usual ones are “burning”, it makes sense to try to buy and test products with an increased gap.

The separator can be metal (not reflected in the number), brass (M on the right), polyamide (TN9), its material greatly affects the price (brass is more expensive).

Analogs

According to the domestic system symbols the bearing has numbers: 105 (open), 180105 (closed with rubber plugs), 80105 (closed with metal washers), 60105 (closed on one side), 50105 (with groove), manufactured according to GOST (8338-75, 520-89, new 520-11), in Russia the product is practically no longer produced and for the most part Chinese bearings are found on sale with such markings, of low quality, but cheap. Current Russian manufacturers are listed in the price table below.

Prices from different manufacturers

The prices are indicative, in US dollars (to keep the information up to date with changing exchange rates), you can count on them if you plan to buy bearings in bulk for organizations (in any store it will be at least 30% more expensive). Prices are given for a closed type bearing with a steel cage (more applicable than others). Open ones are cheaper indicated prices by about 10 - 15%, since their price does not include lubricant and boots.

As you can see, the difference in cost can be very large - there is approximately the same difference in the quality of products from different manufacturers, although in some cases (SKF) there is an overpayment “for famous brand" Based on which unit you plan to install the product in and what the operating conditions will be, you should decide on the brand. If the bearing must be as reliable as possible, it is best to choose from NKE to FAG and SKF. If the speeds and loads are minimal, the cheapest brands will do. Imported bearing 6005 is widespread and often used, so you can buy it from stock quite simply, but it is important to select the optimal supplier (dealer, customer, importer) of a particular brand so as not to overpay to intermediaries.

This is a ball single row radial bearing(there are modifications - in addition to open ( 101 ), there is a closed metal washer on one side ( 60105 ), on both sides ( 80105 ), as well as with a double-sided seal made of oil-resistant rubber ( 180105 ). The latter type has grease already installed at the factory and does not require maintenance, but it also costs a little more.

The type of lubricant is indicated to the right of the main bearing number. The most common lubricants in domestic sealed bearings- с9, с17 and с23. But in fact, this is the last thing that affects the performance of the bearing. Much more important is the accuracy of its execution and the material from which it is made.

Bearing 105 was previously produced with accuracy classes 4, 5, 6, 7, 0 (we remind you that the lower the number indicating the accuracy class, the more expensive and better the quality of the bearing). The material of the separator could be not only metal, but also brass, bronze, or stainless steel. Currently, the domestic industry produces bearings 105, 60105, 80105 and 180105 mainly only with 6th accuracy class from ShKh-15 steel, which is common in the production of bearings.

The product is used in many units. As for its use as a spare part for automotive equipment, it is installed in the LuAZ axle shaft, the driven shaft of the hydraulic coupling of the K-701 tractor engine, etc. It is this bearing that is installed in the door drive of domestic trams.

Reinforced bearings are designated by the letter A before the main designation. Bearings of this standard size are produced at 4 (Samara) (wholesale), 23 factories (Vologda), as well as at the instrument bearings plant.

Imported analogue - bearing 6005 (this designation can also be seen on the rubber seal or washers of some domestic manufacturers). Designations Z, ZZ, 2RS - indicate the presence of protective washers and seals. Manufactured by NSK, FAG, SKF, Koyo, NTN, SNR, Nachi, Timken (expensive and reliable) FBJ, IBC, ISB, NKE, LSA, ZKL (cheaper and worse). The price of this type of main bearing design is about 140 rubles ( best manufacturers), but highly depends on the modification.
