Miniature Ball Bearings with Extended Inner Ring SRW133zz

Miniature Ball Bearings with Extended Inner Ring SRW133zz

The SRW133zz is a compact stainless steel ball bearing with an extended inner ring, measuring just 0.09375″ in bore diameter and 0.1875″ in outer diameter. Its shielded design helps keep out dust while maintaining smooth rotation at speeds up to 72,000 RPM.

Made entirely from stainless steel, it resists corrosion and handles radial loads up to 25 lbf. The extended inner ring makes it easier to install in tight spaces or where precise alignment is needed.

With a temperature range of -86°F to 230°F, it’s suitable for various environments. The bearing requires lubrication for optimal performance. Ideal for small devices like dental tools or precision instruments where space is limited.

Weighing only 0.15g, it’s lightweight yet durable. Compliant with RoHS and REACH standards, it’s a reliable choice for sensitive applications.
