THK LTR-A Compact Rotary Ball Spline

The THK LTR-A Compact Rotary Ball Spline is designed for both rotary and linear motion. Its support bearings are integrated directly into the outer surface of the spline nut. This creates a compact and space-saving unit.

The LTR-A uses a ball spline structure with support bearings for smooth movement and high rigidity. It is suitable for applications where compact construction and reliable rotary motion are important. Solid and hollow spline shaft options are available.

The THK LTR-A is available with 8, 10, 16, 20, 25, 32 and 40 mm spline shaft diameters. Basic dynamic load ratings range from 1.47 to 37.8 kN, while basic static load ratings range from 2.55 to 60.5 kN
