Thomson SUPER12-DD Super Ball Bushing Linear Bearing

Description:

The Thomson SUPER12-DD Super Ball Bushing Linear Bearing is used in precision linear motion systems requiring smooth, low-friction travel on a 0.750-inch precision shaft. Commonly installed in CNC machines, industrial automation equipment, packaging machinery, robotics, semiconductor equipment, and material handling systems, this self-aligning closed linear ball bushing features integral double seals to help protect against contaminants while delivering precise, repeatable linear motion. Maintenance teams, machine builders, and system integrators use this bearing for equipment repair, linear bearing replacement, machine retrofits, and precision motion control applications.

Applications:

The Thomson SUPER12-DD is commonly used in CNC machining centers, automated assembly systems, packaging equipment, inspection machinery, woodworking equipment, medical devices, and custom linear guide assemblies where a self-aligning linear bearing is required for 0.750-inch Thomson Class L precision shafting. Its integral double seals and adjustable design make it ideal for applications requiring long service life, low friction, and protection from dust and debris.
