Parts supplied from our European supplier
A large part of our range is held by our supplier in Germany rather than on our own shelves. We order these in for you as soon as you place the order. They normally dispatch within 7–10 working days, and are then sent on by express courier like anything else. Nothing ships to you direct from Germany — it comes to our Arlesey workshop first, so you deal only with us for returns and warranty.

Measuring 25mm bore × 52mm outer diameter × 15mm width, this bearing is one of the most widely used sizes in automotive gearbox and transmission applications. The C3 clearance designation ensures correct operation under the thermal expansion conditions found in gearbox environments.

- Internal clearance: C3 (greater than normal)
- Cage type: Steel
- Brand: NSK

Cross-reference part numbers: 6205 C3, 6205C3, 6205 C3*NSK
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.
