Inch Size Miniature Flanged Ball Bearings SFR1

Inch Size Miniature Flanged Ball Bearings SFR1

The SFR1 is a miniature flanged ball bearing with a tiny 0.05556″ bore and 0.1875″ outer diameter, crafted entirely from stainless steel for durability. It handles radial loads up to 40 lbf and spins smoothly at speeds up to 81,000 RPM.

Its open design requires lubrication but allows easy maintenance, while the flange keeps it securely in place during operation. The bearing operates well in temperatures from -86°F to 230°F.

With six stainless steel balls and ABEC1 precision, it offers reliable performance in compact spaces. Ideal for small devices like dental tools or precision instruments where space is limited.

Weighing just 0.19g, this lightweight bearing is RoHS and REACH compliant for safe use across various applications. The flange provides extra stability in mounting.
