Types and Features
Cylindrical ball spline LT-X standard type, LT-XL extended type
Cylindrical self-lubricating maintenance-free ball spline MT-X standard type, MT-XL extended type
The nut is more compact than that of the current Model LT thanks to the new circulating pathways. The outer diameter of the nut is the same as that of the linear bushing. The Model LT-XL is suitable for moment loads, torque, and overhung loads that exceed those tolerated by the Model LT-X.
Square flange ball spline LK-X standard type, LK-XL extended type
Square flange self-lubricating maintenance-free ball spline MK-X standard type, MK-XL extended type
The flange is similar to the Model LF, but flattened in four places. Compared to models with round flanges, its core height is lower, and it allows for more compact designs. The Model LK-XL is suitable for moment loads or torque and overhang loads that exceed those tolerated by the Model LK-X.
