10.2 Concept of life for table type TC, TW
The mechanical life of the slider type is represented by that of the linear guide receiving the
greatest moment load.
The operation life of the linear guide is to be determined by the total driving distance reachable
without flaking (peeling on rail surface) in 90% of a group of products operated under the same
conditions.
Operation life can be calculated with the method shown below.
However, regardless of the calculation result, the service life is about 5,000 km or 50 million
cycles (guideline) when it is operated under maximum payload and acceleration/deceleration.
How to calculate operation life
For the operation life of the linear guide, use the dynamic allowable moment stated in "1.2
Mechanical specifications", and calculate with the formula below.
L =
× 5,000km
L: Operation life (km)

: Dynamic allowable moment (N

M: Moment acting (N

In addition, calculate with the formula below if the life may be shortened due to vibration or
mounting status.
