SCS/SBR/TBR/SC-VUU Linear Motion Ball Bearings Diameter 8~60mm Slide Bushing CNC Model (Diameter):TBR20UU (20mm) These tabs let you boltSCS SBR TBR SC VUU Linear Motion Ball Bearings Precision Slide Bushings for CNC & Robotics When shaft misalignment, binding, or inconsistent travel ruins a build, the root cause is almost always a low tolerance bushing. Engineers, CNC builders, and robotics makers who demand repeatable, low friction linear motion need a bearing that stays true across thousands of cycles. These SCS, SBR, TBR, and SC VUU linear motion ball bearings are engineered for
