6801-2RS 12x21x5mm Lightweight Sealed Bearing for Robot Joints & Power Tools Thin Section Ball Bearing

Lightweight, Slim-Wall Construction
The 6801-2RS (12x21x5mm) uses a thin-section cross-section that trims both weight and radial envelope compared with a standard deep-groove bearing of the same bore, which matters directly in moving robotic and motor assemblies.

Engineered for Robot Joints and Power Tools
This size and seal combination is a common fit for robotic joint housings, automotive-grade motors, and handheld power tools, where every gram of rotating mass affects overall system responsiveness.

Rubber-Sealed for Grease Retention
The RS seal keeps factory-fill grease in place and contamination out, supporting the sealed-for-life operation that robotics integrators and tool manufacturers typically specify to avoid field maintenance.

A Practical Weight-Saving Upgrade
For engineers converting a standard bearing position to thin-section geometry, this part offers a straightforward way to reduce joint mass and footprint without redesigning the surrounding housing bore.

Sampling and Documentation Available
Dimensional drawings and sample units ship quickly to support robotics and power tool engineering teams evaluating this thin-section bearing for a new joint or motor design.
