Miniature Ball Bearings with Extended Inner Ring SRW1-4

Miniature Ball Bearings with Extended Inner Ring SRW1-4

The SRW1-4 is a miniature ball bearing with an extended inner ring, measuring just 0.078″×0.25″×0.125″. Made entirely from stainless steel, it offers good corrosion resistance and durability.

It handles radial loads up to 49 lbf and spins at speeds up to 60,300 RPM, making it suitable for high-speed applications. The open design requires lubrication but allows for easy maintenance.

The extended inner ring provides better mounting stability, while the ABEC1 tolerance ensures smooth operation. Its small size and lightweight (0.53g) make it ideal for precision instruments.

Perfect for use in small motors, medical devices, or optical equipment where space is limited. Compliant with RoHS and REACH standards for safe use in various environments.
