Thomson Linear Bearing Shaft Rail 37 x 1.5 In

Description:

The Thomson Linear Bearing Shaft Rail is used in precision linear motion systems to provide a hardened, precision-ground guide shaft with continuous support for linear bearings and pillow block assemblies. Commonly installed in CNC machines, robotics, packaging equipment, automated assembly systems, and material handling machinery, this 37-inch long, 1.5-inch diameter shaft rail features Thomson 60 Case® LinearRace hardened shafting mounted to a continuous support rail for maximum rigidity, reduced shaft deflection, and long service life. Maintenance teams and system integrators use this part for repair, retrofit, expansion, or replacement of continuously supported linear guide systems.

Applications:

The Thomson 1.5-inch Shaft Rail is designed for continuously supported linear motion applications where high rigidity, precision positioning, and reduced shaft deflection are required. It is commonly used with open-style Thomson Super Ball Bushing® bearings in CNC machinery, industrial automation equipment, semiconductor manufacturing systems, packaging machinery, material handling equipment, inspection systems, and custom OEM linear guide assemblies.
