THK LBR Series High Torque Type Ball Spline
The THK LBR Series is built on the heavy load LBST Series, but adds a flange in the central area of the nut. That central flange makes it especially well suited to locations under a moment load, such as the arms of industrial robots, where the load isn’t applied evenly along the shaft.
It’s available in shaft diameters from 15mm to 50mm, with a basic dynamic load rating from 4.4 kN to 55.1 kN and a basic static load rating from 8.4 kN to 94.1 kN.
