Rated life can be calculated using the formula below from the basic dynamic load rating and the actual load applied to the linear bushings.
Number of bushings on one shaft | Contact Factor fc |
---|---|
1 | 1.00 |
2 | 0.81 |
3 | 0.72 |
4 | 0.66 |
5 | 0.61 |
Conditions of Use | fw |
---|---|
No external shocks or vibrations when running in low speed: 15 m/min. or less | 1.0 to 1.5 |
No excessive external shocks or vibrations when running in medium speed: 60 m/min. or less | 1.5 to 2.0 |
External shocks and vibrations given when running in high speed: 60 m/min. or more | 2.0 to 3.5 |
Life in hours can be obtained by calculating travel distance per hour.
If the stroke length and number of strokes are constant, life in hours can be calculated using the following formula.
(1) When mounting Linear Bushings and Housings, use Retaining Rings (Snap Rings), Stoppers, etc.
(2) Linear Bushings are not suitable for rotating motion or usage with repetitive insertion and extraction of shafts. Forced use may cause damage.
(3) If large moment load (offset load) is to be applied, Short/Single Type Linear Bushings are not suitable. Use of Double Type or Multiple Linear Bushings is recommended.
(4) When assembling with linear shafts, forcing the shaft into the bushing with angular misalignment may cause the ball retainers to deform and balls to fall out. Be sure to align the centers and insert the shaft gently.
