Technical calculations

Linear guide life calculations

Operating Life
When a Linear Guide is loaded and used in a linear reciprocating motion, scaly damage called flaking appear due to material fatigue as the stress works on the rolling elements and rolling contact surfaces constantly. Total travel distance until the first flaking occurs is called Life of Linear Guides.
Rated life
Rated life is the total travel distance that 90% of linear guides of the same type can reach, under the same conditions, with no occurrence of flaking damage. Rated life can be obtained from the Basic Dynamic Load Rating and the actual load applied on the linear bushings, as shown bellow.
Load must be calculated before actually using Linear Guides. To obtain load during linear reciprocating motion, it is necessary to fully consider vibration and impact during motion, and also distribution status in relation to Linear Guides. So, it is not easy to obtain load calculation. All these conditions considered, the above-mentioned calculation formula is 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)

For Linear Guide applications, sufficient hardness is required for ball contact shafts.Incorrect material hardness causes less allowable load, resulting in shorter life. Please correct the rated life according to the hardness factors.

Temperature Factor (fT)

If the Linear Guide temperature exceeds 100°C, the Linear Guide and shaft hardness decreases, resulting in less allowable load and shorter life than used at a room temperature. Please correct the rated life according to the temperature factors.
* Please use linear guides under the allowable temperature range shown on each product page.

Contact Factor (fC)

Table-1. Contact factor

Number of Linear Guide on One Shaft Contact Factor fc

1 1.00
2 0.81
3 0.72
4 0.66
5 0.61

In actual applications, 2 or more blocks per shaft are generally used. In this case, the load applied to each block varies depending on the precision of the machining, but is not uniformly distributed.

Load Factor (fW)

Table-2. Load factor

Condition 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 		1.5-20
With shocks/vibrations,
high speed: 60 m/min. or more 		2.0-3.5

To calculate load applied to the Linear Guides, in addition to object weight, it requires inertia force.However, it is difficult to obtain accurate calculations due to potential vibrations and impacts created during the reciprocating motion, beyond the normal start-stop motion.

Applicable load calculation method
When load is applied to a block, convert moment load into applied load using the following formula:
  • P: Applied Load (N)
  • F: Downward Load (N)
  • C0: 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
