FAQ

What does TN9 mean in SKF bearings?

TN9 indicates a glass fiber reinforced polyamide cage designed to reduce friction, weight and operating temperatures.

What is the purpose of C4 clearance?

C4 clearance provides more internal clearance than C3, making the bearing suitable for applications with significant thermal expansion and high operating speeds.

What are the dimensions of SKF 6205 TN9/C4?

The bearing has a 25 mm bore diameter, 52 mm outer diameter and 15 mm width.

Is this bearing suitable for electric motors?

Yes. The SKF 6205 TN9/C4 is commonly used in electric motors due to its high-speed capability and thermal stability.

Can this bearing operate without seals?

Yes. The open design allows external lubrication systems and is often used in applications with controlled lubrication.
