Miniature Flanged Ball Bearings With Extended Inner Ring SFRW0zz

Miniature Flanged Ball Bearings With Extended Inner Ring SFRW0zz

The SFRW0zz is a miniature flanged ball bearing with a tiny 0.04688″ bore and 0.15625″ outer diameter, crafted entirely from stainless steel for durability. It handles radial loads up to 19 lbf and spins remarkably fast at 99,000 RPM.

Its shielded design keeps out dust while the extended inner ring simplifies mounting in tight spaces. The flange adds stability, making it less likely to shift during operation.

This bearing is ideal for small, high-speed devices like dental tools or precision instruments. It operates smoothly in temperatures from -86°F to 230°F.

Weighing just 0.20g, it’s incredibly lightweight yet robust. Pre-lubrication is required for optimal performance. Compliant with RoHS and REACH standards for safe use.
