How Is The Specification Code Of Deep Groove Ball Bearings Indicated?

Open basic structure, commonly used basic code designation, e.g. 6204 bearing structure with snap groove, denoted by 'N' after the model number, e.g. 6204N bearing structure with snap ring.

'NR' is used after the model number, e.g. 6208NR sealed structure with dust cap, Z after the code, Z on one side, 2Z on both sides, e.g. 6204-Z 6204-2Z Non-contact sealing structure, RZ after the code.

One side is RZ, two sides are 2RZ, e.g. 6024-RZ 6204-2RZ contact seal structure, RS after the code indicates Z, both sides are 2RZS: 6024-RS 6204-2RS high load deep groove ball bearing.

Non-standard products can increase the number of steel balls, improve the load capacity, add E after the code, for example: 6210E double row deep groove ball bearings, often 42XX, 43XX two series, for example: 4205, 4305.
