Medium Torque Type Ball Spline Compact Model LF-X Model LF-X
The nut is more compact than that of the current Model LF thanks to the new circulating pathways.
The outer diameter of the nut is the same as that of the linear bushing.
The Model LF-XL is suitable for moment loads, torque, and overhung loads that exceed those tolerated by the Model LF-X.
Models LF4X to 6X are made of stainless steel, which has high corrosion resistance.
basic load ratings(kN) : Basic dynamic load rating 0.42 to 20.8 / Basic static load rating 0.48 to 34.0
Spline shaft diameter (mm) :
3,4,5,6,8,10,13,16,20,25,30
