Rotary Ball Spline with Gear Rotary with Gears Model LBGT Model LBGT
These models are unit types based on model LBR, but have gear teeth on the flange circumference and radial and thrust bearings on the spline nut, all compactly integrated. It is optimal for a torque transmission mechanism with spline nut drive.
basic load ratings(kN) : Basic dynamic load rating 9.4 to 119 / Basic static load rating 20.1 to 213
Spline shaft diameter (mm) :
20,25,30,40,50,60,85
