New THK LT-X & LF-X Interchangeable Ball Splines

THK’s LT-X and LF-X are interchangeable compact ball splines that enable compact, high-speed equipment designs. They are a quick delivery part and available as semi-custom orders.

Reduce Spare Parts Inventory with an Inter-changeable Ball Spline
Failure in a single part of a system can result in large losses. In order to carry out repairs as quickly as possible, it is necessary to have numerous spare parts for every system. Interchange-able compact ball splines can be used as common spare parts, reducing the number of spare parts required. Nuts and spline shafts are offered as single products, enabling easy replacement in case of breakage. The overall shaft length can be specified in 1 mm increments.
Select from three recommended shaft machining shapes:

Model LT-X (Cylindrical Type)
The most compact type with a straight cylindrical nut. When transmitting torque, a key is driven into the body. The LT-X is more compact than the conventional ball spline, Model LT.

Model LF-X Flanged Type
The spline nut can be bolted to the housing using the flange, making assembly simple. It is suitable for locations where the housing may be deformed if a keyway is machined on its surface, or in locations where the housing width is narrow.

Spline Shaft
Interchangeable spline shaft that can be freely combined with LT-X/LF-X. Shaft length available in (mm): 500, 1000, 1500, 2000, 3000. Shaft O.D. (mm): 10, 13, 16, 20, 25, 30.

FEATURES:

• Compact nut shape – The nut is more compact than the conventional Model LT/LF thanks to the new circulating pathways.
• Compact design – Outer diameter up to 10% smaller (Compared to the conventional model). Enables a more compact design of core parts.
• High Speed – Optimal ball circulation and high-speed motion thanks to new circulating pathways.
• Smooth Motion – Reduced rolling resistance compared to the conventional Model LT/LF.
