Miniature Ball Bearings with Extended Inner Ring SRW1

Miniature Ball Bearings with Extended Inner Ring SRW1

The SRW1 is a miniature ball bearing with an extended inner ring, measuring just 0.05556″ in bore diameter and 0.1875″ in outer diameter. Made entirely of stainless steel, it offers good resistance to wear and corrosion.

This single-row bearing handles radial loads up to 40 lbf and can spin at speeds up to 81,000 RPM. Its open design requires regular lubrication for smooth operation.

The extended inner ring makes installation easier, while the ABEC1 tolerance ensures reliable performance. It works in temperatures from -86°F to 230°F.

Ideal for small precision devices like dental tools or miniature motors where space is limited. Weighing only 0.19g, it’s lightweight yet durable for its size. Compliant with RoHS and REACH standards.
