6906-2Z 30x47x9mm Heavy-Duty Shielded Bearing for Robot Base & Arm Joints Thin Section Ball Bearing

Heavy-Duty Thin-Section Bearing
The 6906-2Z (30x47x9mm) is the larger end of the thin-section range in this catalog, built to support the higher radial loads found at a robot's base and main arm joints.

Shielded for Continuous Robotic Operation
ZZ metal shields keep the raceway protected in industrial settings where dust and light debris are present, while keeping running friction low for energy-efficient continuous operation.

Matched to Robot and Automotive Motor Duty
This size is a practical fit for both robot base joints and larger automotive motor assemblies, giving OEMs flexibility to use one bearing across two product categories.

Built for Long Service Life Under Load
Larger cross-section relative to bore than smaller thin-section sizes gives this bearing extra margin for the sustained moment loads typical of a robot's primary structural joints, supporting longer intervals between maintenance checks.

Available for Base-Joint Qualification
Drawings and cycle-life data are available to support the structural qualification testing robotics manufacturers typically run on primary base and arm joint bearings.
