Miniature Ball Bearings with Extended Inner Ring RW1810

Miniature Ball Bearings with Extended Inner Ring RW1810

The RW1810 is a miniature ball bearing with an extended inner ring, measuring 0.3125″ in bore diameter and 0.5″ in outer diameter. Made from chrome steel, it’s lightweight at just 1.72g and handles radial loads up to 104 lbf.

Its open design and stainless steel cage allow for smooth operation at speeds up to 40,000 RPM. The extended inner ring makes it easier to install and align in tight spaces.

This bearing is suitable for applications like small motors or precision instruments where space is limited. It operates in temperatures from -86°F to 230°F and requires regular lubrication.

Compliant with RoHS and REACH standards, it’s a reliable choice for both industrial and hobbyist use. The ABEC1 tolerance ensures decent precision for most general-purpose needs.
