Miniature Ball Bearings with Extended Inner Ring SRW133

The SRW133 is a miniature ball bearing with an extended inner ring, measuring just 0.09375″×0.1875″×0.0937″. Made entirely from stainless steel, it offers good corrosion resistance and durability.

This bearing handles radial loads up to 25 lbf and can spin at impressive speeds up to 72,000 RPM. Its open design requires lubrication but allows for easy maintenance when needed.

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

Ideal for small precision devices like dental tools or miniature motors where space is limited. Compliant with RoHS and REACH standards, it’s a safe choice for sensitive applications. Weighing only 0.15g, it’s remarkably lightweight.
