Inch Size Miniature Flanged Ball Bearings SFR144zz

Inch Size Miniature Flanged Ball Bearings SFR144zz

The SFR144zz is a compact flanged ball bearing with a 0.125″ bore and 0.25″ outer diameter, crafted entirely from stainless steel for durability. Its small size (0.125″×0.296″×0.1094″) makes it ideal for tight spaces, while the flange keeps it securely in place.

Shielded on both sides, this bearing offers protection against dust and debris without sacrificing speed, handling up to 60,300 RPM. It supports radial loads up to 49 lbf and operates smoothly in temperatures from -86°F to 230°F.

The stainless steel cage and balls ensure long life, and the ABEC1 tolerance provides reliable performance. Lightweight at just 0.48g, it’s perfect for small devices like drones or precision instruments where space and weight matter.

Requiring lubrication for optimal performance, this bearing is RoHS and REACH compliant. Its shielded design and flange make it a practical choice for applications needing secure mounting and contamination protection.
