THK ST25 Linear Rotary Ball Bearing 25x37x45mm LM Stroke Bushing

The THK ST25 is a genuine THK LM Stroke ST series linear/rotary ball bearing — a compact ball bushing that supports linear motion, rotary motion and compound motion within a single unit. Unlike a conventional linear bearing that only moves along a shaft, the ST type uses a precision-ground cylindrical outer sleeve with an embedded ball cage and balls. The balls are arranged in a staggered pattern to distribute load evenly, and the lightweight light-alloy cage follows high-speed motion. Thrust rings and retaining rings at both ends prevent the cage from overrunning
