Thomson QS 12 MM 1000 Quick Shaft Linear Shaft 40In

Description:

The Thomson QS 12 MM 1000 Quick Shaft Linear Shaft is used in precision linear motion systems requiring accurate shaft guidance, high wear resistance, and smooth bearing travel. Commonly installed in CNC machines, industrial automation equipment, packaging machinery, material handling systems, and automated assembly equipment, this 12 mm hardened carbon steel shaft measures approximately 40 inches (1,000 mm) in length and is designed for use with Thomson ball bushings and linear bearings. Maintenance teams and system integrators use this shaft for repair, retrofit, expansion, or replacement of precision linear motion systems.

Applications:

The Thomson QS 12 MM 1000 is commonly used in CNC routers, robotics, pick-and-place systems, packaging equipment, inspection machines, conveyor systems, laboratory automation, and other industrial applications requiring rigid, precision-ground linear shafting with excellent wear resistance and smooth linear motion.
