Technical calculations
■Linear guide life calculations
- ●Life
- 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 is the "Life" of the linear system.
- ●Rated life
- Rated life is a total distance 90% of linear guides reach without flaking when a group of the same guides are run under the same condition. The rated life can be calculated with basic dynamic load rating and the load applied on the guides as follows.
-
- When using linear guides, load calculations are initially needed. It is not easy to calculate the loads during linear motion due to vibrations and shocks, as well as load distribution on the guides. Furthermore, operating environment temperature has large effect on life. When these conditions are taken in consideration, the calculations would be as follows.
-
- L: Rated life (km)
- fH: Hardness factor (see Fig-1)
- fT: Temperature factor (see Fig-2)
- fC: Contact factor (see Table-1)
- fW: Load factor (see Table-2)
- C: Basic dynamic load rating (N)
- P: Applicable load (N)
- ●Hardness factor (fH)
-
In using linear guides, the shaft that balls contact must have sufficient hardness, If adequate hardness cannot be obtained, load rating decreases and life will be reduced as a result.
Please compensate the life rating with hardness factor.
- ●Temperature factor (fT)
-
When the temperature of linear guides exceed 100°C, hardness of blocks and rails will be reduced, causing reduction of life. Please compensate the life rating with temperature factor.
* Please use linear guides within temperature shown on product pages.
- ●Contact factor (fC)
-
Table-1. Contact factor
Number of blocks installed on one rail and contact factor fC
1 | 1.00 |
2 | 0.81 |
3 | 0.72 |
4 | 0.66 |
5 | 0.61 |
In general, it is common to use 2 or more blocks on 1 rail. In such case, load applicable on each block would not be uniform due to machining variations. As the result, allowable load rating on each block would vary depending on the number of blocks used per rail. Please compensate the life rating with contact factor shown on Table-1.
- ●Load factor (fW)
-
Table-2. Load factor
Application condition | fw |
No external shocks or vibrations and speed is low 15m/min or less | 1.0 - 1.5 |
No significant shocks or vibration and med. speed 60m/min or less | 1.5 - 20 |
External shocks and vibrations exist and the speed is high 60m/min or over | 2.0 - 3.5 |
When calculating loads applicable on linear guides, other than the weight of the object, inertial force due to motion speeds, moment loads, and variations of each over time must also be obtained accurately. However, accurate calculation would be difficult due to repeated starts and stops and various shocks and vibrations. Therefore, the Load Factors shown in Table-2 are used to simplify the life calculations.
- ●Applicable load calculation method
- When moment loads apply a block, use the following formula to convert the moment load to applicable load.
-
- P: Applicable load (N)
- F: Downward load (N)
- Co: Static load rating (N)
- MA: Allowable static moment - Pitching direction (N・m)
- MC: Allowable static moment - Rolling direction (N・m)
- Lp: Load point distance (m) in pitching direction
- Lr: Load point distance (m) in rolling direction
