Bearing 62203 2RS. Analogue 180503 according to GOST. Marking 62203 rs, 62203 ee

Bearing 62203 2RS - ball single-row, designed for radial loads. From bearing 6203 it is more wide: 16 mm versus 12 mm, therefore it can be searched as a wide 6203. Closed with rubber covers (plastic seals), which protect the rolling elements and tracks from ingress of small debris and dust. Also reliably protected from moisture and water due to the tightness of the plugs. The operating temperature range is determined by the lubricant applied at the factory; the standard limit is +120 degrees Celsius. Additional lubrication during the operation is not required, since it is possible to cause a confluct of lubricants and significantly shorten the service life of the product. In addition, in the case of opening the bearing manufacturer’s warranty does not apply.

For lightly loaded nodes with low rotational speeds, it is allowed to use inexpensive bearings of such companies as CRAFT Lithuania or CX Poland. Products of medium category companies - for example, ZVL Slovakiaили FBJ Japan - Suitable for old cars and agricultural equipment. In case the product is installed in expensive equipment, the use of expensive brands is recommended: SNR France (marked 62203 EE), TIMKEN USA, FAG Germany or SKF Sweden.
