Metal-Shielded Deep Groove Ball Bearing – 6801-2Z (12 × 21 × 5mm)
LASER PARTS | BEARINGS & MOTION COMPONENTS
Compact, Metal-Shielded Bearing for Smooth Rotation
The 6801-2Z deep groove ball bearing provides smooth rotational movement for compatible laser machine components and other mechanical equipment. Featuring a 12 mm inner diameter, 21 mm outer diameter, and 5 mm width, this compact steel bearing is designed for applications requiring precise dimensional fit.
Metal shields on both sides help protect the internal bearing components from larger dust particles and debris. Its shielded construction makes it a practical replacement for worn or damaged bearings requiring the same dimensions and configuration.

Check Compatibility Before Ordering
Confirm the inner diameter, outer diameter, width, and bearing configuration match your existing component. Similar-sized bearings may use different shields, seals, or internal clearances.
Metal-shielded bearings are not completely sealed against moisture or fine contamination. Confirm that this configuration is appropriate for your equipment.
Installation Note: Use the appropriate bearing installation method for your application. Avoid transferring installation force through the bearing balls.
