Thomson SSETWN-M30-XS Super Smart Ball Bushing Twin Pillow Block Linear Bearing

Description:

The Thomson SSETWN-M30-XS Super Smart Ball Bushing Twin Pillow Block Linear Bearing is used in precision linear motion systems to provide smooth, self-aligning motion on 30 mm metric shafts. Commonly installed in CNC machines, industrial automation equipment, robotics, packaging machinery, semiconductor equipment, and material handling systems, this twin closed pillow block assembly features two factory-installed Super Smart Ball Bushings housed in a black anodized aluminum body for increased load capacity and rigidity. Maintenance teams and system integrators use this part for repair, retrofit, expansion, or replacement of end-supported metric linear shaft systems.

Applications:

The Thomson SSETWN-M30-XS is designed for end-supported metric shaft applications requiring high load capacity, low-friction operation, and automatic compensation for shaft and housing misalignment. It is widely used in CNC machining centers, automated assembly equipment, robotics, packaging systems, medical devices, semiconductor manufacturing, inspection equipment, and custom OEM machinery utilizing 30 mm Thomson MM shafting. The twin pillow block design provides greater rigidity and load distribution than a single pillow block while maintaining precise, self-aligning linear motion.
