THK LBF30UUCL215L Linear Spline Bush Bearing

Description:

The THK LBF30UUCL215L Precision Medium Load Linear Spline Bush Bearing is a recirculating ball linear spline bearing designed to provide smooth linear motion while simultaneously transmitting torque through a precision splined shaft. Featuring a 30 mm nominal shaft diameter and medium preload (CL), this linear spline bush delivers high rigidity, accurate positioning, and reliable torque transmission in compact automation systems. Commonly installed in industrial robots, semiconductor manufacturing equipment, automated assembly machines, packaging systems, and precision handling equipment, this bearing is used by maintenance teams, OEM machine builders, and system integrators for machine repairs, retrofits, and replacement of worn linear spline bearings.

Applications:

The THK LBF30UUCL215L is commonly used in industrial robots, pick-and-place equipment, semiconductor manufacturing systems, electronic assembly machines, automated inspection equipment, packaging machinery, material handling systems, CNC automation, and precision positioning applications where simultaneous linear motion and torque transmission are required.
