How long is the life of linear guide?
Time:2021-01-26
Usually, the linear guide system is damaged by metal fatigue caused by reciprocating pressure. Reciprocating pressure makes the skin of linear guide and ball fall off. The life of the linear guide is the total travel of the system when the linear guide or ball skin falls off.
Basic static load rate: CO (KGF)
If overload or vibration acts on the static or moving linear guide system, the ball and linear guide will produce permanent deformation. When the deformation is too large, it will affect the smooth operation of linear guide system. The static load rate of base wood C. It refers to the constant load of the same direction and strength when the total deformation of the ball and linear guide under the maximum static load condition is equal to 1 / 10000 of the ball diameter. Static load rate C. The maximum allowable static load of linear guide is shown.
Static safety factor: FS
There are two ways to select linear guide. One is based on the static load system; the other is based on the service life. Usually we use the second one.
Basic dynamic load rate: C [KGF]
The dynamic load rate C90% of the base timber is a statistical figure that the linear guide rail runs up to 50km under full load.
Calculation of load rate and life
Because of repeated pressure, the contact surface of linear guide will produce debris falling off. Rated life is the total travel of the same linear guide system running under the same conditions one by one without 90% of the base falling off.
