Why does my gearbox bearing need C3 clearance?

C3 (greater-than-normal) internal clearance is specified for applications where the bearing will heat up during operation, causing the inner ring to expand onto the shaft. Without this extra clearance, the bearing would become over-constrained and fail prematurely. Most gearbox bearings are C3.

Is this a genuine NSK bearing?

Yes. Supplied direct from NSK, one of Japan's leading precision bearing manufacturers. NSK bearings are used extensively as original equipment by major transmission makers.

Can I use this bearing in an electric motor or other applications?

Yes — 6205 C3 is a universal standard bearing used in motors, gearboxes, pumps, and agricultural equipment. The C3 clearance suits higher-temperature applications.

What is the difference between 6205 and 6205 C3?

The C3 suffix denotes a greater-than-normal internal clearance to accommodate thermal expansion. A standard 6205 (CN clearance) is suitable for room-temperature applications; 6205 C3 is required wherever operating temperatures exceed approximately 50°C.
