Miniature Ball Bearings with Extended Inner Ring SRW2-5

Miniature Ball Bearings with Extended Inner Ring SRW2-5

The SRW2-5 is a miniature ball bearing with an extended inner ring, measuring 0.125″ in bore diameter and 0.3125″ in outer diameter. Made entirely from stainless steel, it offers good corrosion resistance and durability.

This single-row bearing handles radial loads up to 96 lbf and can spin at speeds up to 54,000 RPM. Its open design requires regular lubrication but allows for easy maintenance.

The extended inner ring provides better mounting stability, while the ABEC1 tolerance ensures reliable performance. With a temperature range of -86°F to 230°F, it suits various environments.

Ideal for small mechanisms like dental tools or precision instruments where space is limited. Weighing just 0.74g, it’s lightweight yet sturdy for its size. Compliant with RoHS and REACH standards.
