THK LBST Series High Torque Type Ball Spline
The THK LBST Series is the heavy load version of the LBS Series, sharing the same spline nut diameter but with a longer nut length. That extra length makes it a strong choice for locations with limited space where a large torque, an overhang load, or a moment load is applied, since the longer nut spreads the load over a greater contact area.
It’s available in shaft diameters from 20mm to 150mm, with a basic dynamic load rating from 9.4 kN to 196 kN and a basic static load rating from 20.1 kN to 405 kN, giving it a notably higher capacity than the standard LBS Series.
