Snap Ring Groove Ball Bearings 6308-ZNR

Snap Ring Groove Ball Bearings 6308-ZNR

The 6308-ZNR is a shielded ball bearing with a 40mm bore and 90mm outer diameter, designed for radial loads. It’s built from chrome steel for durability and can handle dynamic loads up to 9509 lbf.

With a snap ring groove on the outer ring, it stays securely in place during operation. The stainless steel cage ensures smooth rotation, even at speeds up to 11,000 RPM.

This bearing works well in temperatures from -30°C to 120°C and comes pre-lubricated with grease for easy maintenance. It’s interchangeable with SKF models, making replacements straightforward.

Ideal for machinery where radial loads and secure positioning are key, such as pumps or electric motors. Weighing 0.65kg, it’s a sturdy yet manageable choice for industrial applications.
