Thin Section Ball Bearings 6905

Thin Section Ball Bearings 6905

The 6905 is a slim, single-row ball bearing with a 25mm bore and 42mm outer diameter, designed for radial loads. Its compact 9mm width makes it ideal for tight spaces, while chrome steel construction ensures durability.

It handles radial loads up to 1577 lbf and spins smoothly at speeds up to 19,000 RPM. The open design allows for easy lubrication, and the stainless steel cage keeps everything in place during operation.

With a temperature range of -30°C to 110°C, this bearing suits various environments. Its ABEC-1 tolerance and C0 radial clearance provide reliable performance without being overly precise.

Weighing just 47g, it’s lightweight yet sturdy. Compliant with RoHS and REACH standards, it’s a practical choice for machinery where space and radial load capacity matter.
