High Torque Type Ball Spline High Torque Model LBST Model LBST
A heavy load type that has the same spline nut diameter as model LBS, but has a longer spline nut length. It is optimal for locations where the space is small, a large torque is applied, and an overhang load or moment load is applied.
basic load ratings(kN) : Basic dynamic load rating 9.4 to 196 / Basic static load rating 20.1 to 405
Spline shaft diameter (mm) :
20,25,30,40,50,60,70,85,100,120,150

Notes on dimensional table
- Note) ○: indicates model numbers for which high temperature types are available (with metal retainer; service temperature: up to 100℃).
●:indicates model numbers for which felt seal types are available ( See Contamination Protection).
A felt seal cannot be attached to Ball Spline models using metal retainer. - Note) ** MA.1 indicates the permissible moment value in the axial direction when a single spline nut is used, as shown in the figure above.
**MA.2 indicates the permissible moment value in the axial direction when two spline nuts in close contact with each other are used, as shown in the figure above.
For details on the maximum lengths of ball spline shafts by accuracy, please see Maximum Manufacturing Length by Accuracy.
