THK America, Inc. Datasheets for Ball Splines

Ball splines provide nearly friction-free linear motion while simultaneously transmitting torsional loads. The path of the bearing balls is straight, not helical, which allows for a very efficient coupling device suitable for a variety of applications.

Product Name Notes
Ball Spline -- LTR A compact unit type whose support bearings are directly integrated with the outer surface of the spline nut.
Ball Spline, Cylindrical Nut -- DP
Ball Spline, Flanged Nut -- DPM
Since the spline shaft’s surface is provided with a mirror finish, smooth slide is achieved. In addition, the large contact area and the concentricity, which enables the center to be...
Ball Spline, Cylindrical Nut -- LBS The most compact type with a straight cylindrical spline nut. When transmitting a torque, a key is driven into the body. The outer surface of the spline nut is provided...
Ball Spline, Cylindrical Nut -- LT The most compact type with a straight cylindrical spline nut. When transmitting a torque, a key is driven into the body.
Ball Spline, Flanged Nut -- LBF
Ball Spline, Flanged Nut -- LF
The spline nut can be attached to the housing via the flange, making assembly simple. It is optimal for locations where the housing may be deformed if a keyway is...
