THOMSON SPPBOAM12 BALL BUSHING PILLOW BLOCK 12MM SHAFT #164412

Description:

The Thomson SPPBOAM12 Super Ball Bushing Pillow Block is used in precision linear motion systems requiring smooth, self-aligning travel on 12 mm continuously supported shafts. Commonly installed in CNC machines, factory automation equipment, packaging machinery, robotics, semiconductor equipment, and automated manufacturing systems, this open, adjustable Super Ball Bushing® pillow block features a self-aligning recirculating ball bushing housed in a lightweight aluminum block for precise, low-friction linear motion. Maintenance teams and system integrators use this part for repair, retrofit, expansion, or replacement of supported metric linear guide systems.

Applications:

The Thomson SPPBOAM12 is designed for use in continuously supported metric shaft applications where high accuracy, low friction, and reliable linear guidance are required. It is commonly found in automated assembly equipment, CNC machinery, packaging systems, laboratory instruments, material handling equipment, robotics, inspection systems, and custom OEM machines requiring compact, self-aligning linear bearings.
