■Life of Flanged Linear Bushings
When the linear system is in motion with applied load, the rolling surfaces and races are subject to repeated stress, This stress can cause scale-like flaking due to material fatigue. The total run distance until the flaking appears in the "Life" of the linear system.
Rated life can be calculated with the basic dynamic load rating and the actual load applied on the linear bushings, as shown below.
●Hardness factor (fH)
For linear applications, the linear shaft must have sufficient hardness. If it does not, the load rating decreases and the life will be reduced.
Fig. 1. Hardness Factor.
●Temperature factor (fT)
When the temperature of the linear system exceeds 100 degrees C, the hardness will decrease and as a result, the allowable load and life will reduced.
Fig. 2. Temperature Factor.
●Contact factor (fC)
In general, it is common to use two or more bushings on one shaft. In these cases, the load on each bushing will vary depending on the machining precision and will not have equally distributed loads. As a result, the allowable load per bushing will vary depending on the number of bushings used on the shafts. Please compensate the rated life with contact factors on Table-1.
Table-3. Contact Factor.
Number of Bearings Installed on One Shaft | Contact factor fC | |
---|---|---|
1 | 1 | |
2 | 0.81 | |
3 | 0.72 | |
4 | 0.66 | |
5 | 0.61 |
●Load Factor (fW)
To calculate the load applied to the bushings, in addition to the object weight, the inertia force attributed to the motion velocity, moment loads and the variations of each over time must be obtained. However, for reciprocating motion applications, it is difficult to obtain accurate calculations due to the effects of the vibrations and shocks. Therefor, use Table 2 to simplify the life calculations.
Conditions of Use | fw |
---|---|
No shocks vibrations,low speed: 15 m/min. or less | 1.0~1.5 |
No significant shocks vibrations,medium speed: 60 m/min. or less | 1.5~2.0 |
With shocks vibrations, high speed: 60 m/min. or more | 2.0~3.5 |
Life in hours can be obtained by calculating the travel distance per hour. When the stroke length and the number of strokes are constant, it can be calculated using the formula below.
