Thin Section Ball Bearings S6918zz

Thin Section Ball Bearings S6918zz

The S6918zz is a thin-section ball bearing with a 90mm bore and 125mm outer diameter, crafted entirely from stainless steel for durability. Its compact 18mm width makes it ideal for space-sensitive applications while handling radial loads up to 6636 lbf.

Shielded on both sides, this bearing keeps contaminants out while maintaining smooth operation at speeds up to 4600 RPM. The stainless steel cage ensures consistent performance, even in temperatures ranging from -86°F to 230°F.

With ABEC-1 precision and C0 radial clearance, it offers reliable rotation for moderate-speed applications. Regular lubrication is recommended to maintain its efficiency.

This model suits equipment like medical devices or robotics where slim profiles and corrosion resistance are key. Compliant with RoHS and REACH standards, it weighs 565g for easy handling.
