THOMSON SSUTWN-12XS TWIN PILLOW BLOCK XS SSUTWN12XS

Description:

The Thomson SSUTWN-12XS Super Smart Ball Bushing Twin Pillow Block is used in precision linear motion systems to provide smooth, self-aligning linear travel on 0.750-inch (3/4-inch) Class L round shafts. Commonly installed in CNC machinery, industrial automation equipment, robotics, packaging systems, semiconductor equipment, and material handling applications, this closed twin pillow block features two factory-installed Super Smart Ball Bushings®, a black anodized aluminum housing, and high load capacity for end-supported shaft applications. Maintenance teams and system integrators use this part for repair, retrofit, expansion, or replacement of precision round shaft linear guide systems.

Applications:

The Thomson SSUTWN-12XS is designed for end-supported Class L shaft applications requiring greater rigidity, increased load capacity, and accurate self-aligning linear motion. Its twin bearing configuration provides improved stability and longer travel life, making it ideal for CNC machining centers, automated assembly equipment, robotics, packaging machinery, semiconductor manufacturing, inspection systems, and other high-precision OEM linear motion applications.
