Open Thin Section Bearings provide an ultra-compact design with constant cross-section dimensions across a wide bore range. The open configuration allows for integration into oil-lubricated systems or minimal-friction environments. Available in multiple precision grades up to ABEC 7 for high-speed, high-accuracy applications. Ideal for robotics rotary joints, radar antenna mounts, semiconductor wafer handling equipment, and aerospace gimbal systems where space, weight and precision are critical constraints.
