Thomson Super12 Super Ball Bushing Linear Bearing

Description:

The Thomson SUPER12 Super Ball Bushing Linear Bearing is used in precision linear motion systems to provide smooth, low-friction, self-aligning movement on 0.750-inch precision shafting. Commonly installed in CNC machines, automated assembly equipment, robotics, packaging machinery, inspection systems, and industrial automation applications requiring accurate linear guidance. Maintenance teams and system integrators use this linear bearing for equipment repairs, machine rebuilds, automation retrofits, and replacement of worn linear bearings to restore precise and reliable motion.

Applications:

The Thomson SUPER12 Super Ball Bushing Linear Bearing is designed for end-supported linear shaft applications where high load capacity, self-alignment, and smooth travel are essential. It is widely used in CNC machining centers, pick-and-place systems, semiconductor equipment, medical devices, material handling machinery, and OEM automation systems utilizing Thomson Class L precision shafting. Its self-aligning design compensates for minor shaft misalignment while maintaining excellent positioning accuracy and long service life.
