Miniature Ball Bearings with Extended Inner Ring SRW4

Miniature Ball Bearings with Extended Inner Ring SRW4

The SRW4 is a small stainless steel ball bearing with a 0.25″ bore and 0.625″ outer diameter, designed for radial loads. Its extended inner ring makes installation easier, while the open design allows for simple lubrication.

With a dynamic load capacity of 255 lbf, it handles moderate forces smoothly. It spins at speeds up to 34,200 RPM, suitable for fast-moving applications.

The stainless steel construction resists corrosion, and the ABEC1 tolerance ensures reliable performance. It operates in temperatures from -86°F to 230°F.

Ideal for small machinery or instruments where space is limited. Its lightweight design (4.54g) and compliance with RoHS/REACH standards make it a practical choice.
