Technical Calculations
■Calculation of Service Life of Ball Spline
Use the following formula for calculating the running service life of the ball spline.
- L: Running Life (km).
- ft: Temperature Factor.
- fh: Hardness Factor.
- fp: Ratio of Rated Load.
- fw: Load Factor.
- L0: Rated Life (50km).
- C: Basic Dynamic Load Rating (N).
- F: Applied Radial Load (N).
- Ct: Basic Dynamic Torque (N·m).
- T: Applied Torque (N·m).
Use the following formula for calculating the service life of the ball spline.
- Lh: Run Time (hr).
- L: Running Life (km).
- St: Stroke Length (mm).
- n: Reciprocating Cycles per Minute (cpm).
■Ratio of Rated Load (fp)

10 | φ10.4 | 1 | 0.71 |
13 | φ13.4 | 1 | 0.71 |
16 | φ16.6 | 1 | 0.68 |
■Load Factor (fw)
Usage Condition | Load Factor (fw) |
Minimal vibrations shocks (slow speed travel 1 to 2 15 m/min or less) | 1-2 |
Some vibrations shocks(medium speed travel 2 to 3 60 m/min or less) | 2-3 |
Severe vibrations shocks (high speed travel 3 or more over 60m/min.) | 3- |

IDEA NOTE A ball spline mechanism that works as a guide
The ball spline not only allows for up and down motion, but also shaft rotary motion for guiding and transferring of workpiece.
IDEA NOTE Clamping work center
The rotation clamp is designed as a mechanism to allow for positioning adjustments.
