Thin Section Bearings for Robotics

Application

Typical Robotics Applications

Robot Base Rotation

Large-diameter compact support for robot bases requiring stable rotation and combined load capacity.

Robot Joints & Arms

Low-weight support for shoulder, elbow and wrist joints with limited radial space.

End Effectors

Compact bearings for grippers, tool changers and rotary end-of-arm modules.

Collaborative Robots

Low friction, compact size and smooth motion for lightweight collaborative robot joints.

Mobile Robot Rotary Modules

Thin section solutions for sensor platforms, steering modules and compact rotary mechanisms.

Requirements

Application Design Requirements

Limited Joint Space

Robot joints often require a large bore for cables and drives while keeping the external diameter and cross-section small.

Combined Loads & Tilting Moment

Robot joints may carry radial, axial and overturning loads at the same time.

Positioning Accuracy

Repeatable motion requires controlled runout, smooth rotation and stable axial/radial positioning.

Low Weight & Low Friction

Reducing rotating mass improves acceleration, energy efficiency and motion response.

Cable & Hollow-Shaft Layout

Large internal diameter may be needed for cables, reducers and service lines.

Types

Recommended Bearing Structures

Deep Groove Thin Section Ball Bearings

Support radial loads and moderate axial loads with low friction and compact cross-section.
