Compact Ball Splines LFK-X and LFH-X

New compact Ball Splines LFK-X and LFH-X


Allows constructions with a compact design

The models LFK-X and LFH-X are designed with a lower middle flange height than the conventional model LF-X. This enables more compact designs and space-saving connections of peripheral components.


Lighter Weight

The modified flange shape makes the weight of the spline nut lighter than the round-flanged Model LF-X, reducing the weight of devices.



The lineup features nine sizes ranging from Ø5 to Ø30 mm with two types of spline nuts: standard type and long type (Ø5 to Ø8 mm).
