Bearing 6203 2RS. Analogue of GOST 180203. 17*40*12 Marking options 6203rs, 6203 llu, 6203 ddu, 6203 ee, bearing 6203 closed

Bearing 6203 2rs - single-row radial ball with dimensions 17x40x12 mm. It consists of two rings (holders) with raceways, between which rolling elements are located in the separator - balls. It perceives loads directed perpendicular to the shaft axis. The lubricant is applied at the factory in an amount that is sufficient for the entire service life. The addition of grease to closed-type bearings is strictly prohibited - interfering with the product may lead to contamination, defects in the internal cavity, and also cause a conflict of lubricants, which ultimately adversely affects the quality of work and the service life of the assembly. From running out of grease during operation, as well as from the ingress of dust, dirt and moisture, the bearing is protected by rubber seals. They are more hermetic than metal washers, but they are designed for lower revs.
Analogue in accordance with GOST - 180203.

The bearing is one of the most popular in the 62xx lineup, which causes a wide range of products from various manufacturers. Products inexpensive brands such as CT China,  CRAFT Lithuania or CX Poland suitable for nodes with low rotational speeds and light loads. For nodes of increased responsibility, it is recommended to choose a premium class: Koyo Japan or SKF Sweden. In other cases, the most optimal in terms of price / quality ratio are firms. FLT Poland , FBJ Japan and ZKL Czech.
Marking may differ from the classic (6203-rs or 6203 rs). Some manufacturers have their own bearing designation system. Thus, the products of the company ZVL (Slovakia) are labeled 6203 2rsr, 6203 2nse 9 - NACHI (Japan), 6203 EE - SNR (France), 6203 DDU - NSK (Japan), 6203 llu - NTN(Japan), 6203 c 2hrs - FAG (Germany).
Marking applied on protective covers, for more expensive brands, it is also duplicated at the end of the inner and / or outer ring. Full marking is applied to the box in which the bearing is delivered.

Main technical and parametric characteristics:

• Internal diameter of the bearing d - 17 mm;

Drawing, type and general view of the bearing 6203rs

Bearing applied in Soviet cars VAZ 1111 Oka in the drive fan; ZAZ (1103, 110206, 1105) - in the water pump of the engine and the generator of the front and rear supports; IZH2.673 motorcycle on both wheels; combine KPI2.4 in the header for harvesting crops. Also very popular in imported agricultural machinery. In particular, it is used in CLAAS combine harvesters (COMMANDOR, DOMINATOR, LEXION, LEXION MONTANA, MEGA, TUCANO - various series), CLAAS XERION tractors, CLAAS JAGUAR combine harvesters, NEW HOLLAND combines (CS, CSX, CX, TC series).
