| High torque Caged Ball type |
|
Type SLS
Type SLS-L |
|
Nominal shaft
diameter
25 to 100 mm |
Details |
- Redesigning the shape of the conventional high torque type spline shaft to be morecircular significantly improves its torsion and flexural rigidity.
- Models SLS/SLF adopt the caged-ball technology to enable the circulating motion of evenly spaced balls to be maintained and high-speed response to be achieved, the cycle time of the machine can be improved.
- Models SLS/SLF adopt the caged-ball technology, they eliminate collision and mutual friction between balls, and realize low noise,pleasant running sound and low particle generation.
- Models SLS/SLF adopt the caged-ball technology to substantially increase the grease retention, thus achieving long-term maintenance-free operation.
- Models SLS/SLF adopt the caged-ball technology and a new circulation method, thus achieving stable and smooth motion withsmall rolling fluctuation.

Details
Details |
- The spline shaft has three crests equidistantly formed at angles of 120°. On both sides of each crest, two rows (six rows intotal) of balls are arranged to hold the crest from both sides. The angular-contact design of the ball contact areas allows an appropriate preload to be evenly applied.
- Since the balls circulate inside the spline nut, the outer dimensions of the spline nut are compactly designed.
- Even under a large preload, smooth straight motion is achieved.
- Since the contact angle is large (45°) and the displacement is minimal, high rigidity is achieved.
- No angular backlash occurs.
- Capable of transmitting a large torque.

- The spline shaft has two to three crests. On both sides of each crest, two rows (four tosix rows in total) of balls are arranged to hold the crest from both sides. This design allowsan appropriate preload to be evenly applied.
- The contact angle of 20° and an appropriate preload level eliminate angular backlash, providing high-torque moment rigidity.

Details |
|
|
Type LT-X |
|
Nominal shaft
diameter
4 to 30 mm |
Details |
- The length and external diameter of the LT-X ball spline’s outer cylinder are the same as those of an LM-series linear bushing, meaning the nut can be replaced with a linear bushing.

| Type LF-X |
|
Nominal shaft
diameter
4 to 30 mm |
Details |
- The length and external diameter of the LF-X ball spline’s nut are the same as those of theModel LMF linear bushing, meaning the nut can be replaced with a linear bushing.
|
| Type LFK-X |
|
