THOMSON SSUFB20 BALL BEARING SUPER SMART PILLOW BLOCK

Description:

The Thomson SSUFB20 Super Smart Ball Bushing Flanged Pillow Block Linear Bearing is used in precision linear motion systems to provide smooth, self-aligning motion on 1.250-inch precision shafts. Commonly installed in CNC machines, industrial automation equipment, robotics, packaging machinery, semiconductor equipment, and material handling systems, this closed flanged pillow block features a factory-installed Super Smart Ball Bushing®, a rigid aluminum housing, and integral double-acting seals for reliable, low-friction operation. Maintenance teams and system integrators use this part for repair, retrofit, expansion, or replacement of inch linear shaft systems requiring secure flange mounting and precise linear guidance.

Applications:

The Thomson SSUFB20 is designed for end-supported Class L shaft applications requiring high load capacity, smooth linear travel, and automatic compensation for shaft and housing misalignment. It is widely used in CNC machining centers, automated assembly systems, robotics, semiconductor equipment, packaging machinery, medical devices, inspection systems, and custom OEM automation. The flanged aluminum housing simplifies installation while the patented Super Smart Ball Bushing® technology delivers quiet operation, long service life, and superior load distribution.
