THK 0al Ball Spline Flange Bearing Solid Shaft

The THK medium-load ball spline flange bearing with solid shaft combines linear motion and torque transmission in a single assembly, featuring an effective travel length of 609 mm and an overall shaft length of 940 mm. A round flange mount secures a solid ball spline shaft with recirculating steel balls to deliver high torque capacity, high rigidity, and smooth, low-friction operation. The shaft is made from hardened and precision-ground bearing steel and the nut from hardened bearing steel, with lubrication compatible for grease or oil to support long service life. This configuration is well suited for CNC machine tools, industrial robots, semiconductor equipment, automated assembly systems, packaging machinery, and precision handling equipment, and is commonly used by maintenance teams, OEM machine builders, and system integrators for installations, repairs, retrofits, and worn-ball-spline replacements. Common replacements include THK SLF Series, SLS Series, and LBF Series ball spline assemblies.
