Linear ceramic shaft selection process and steps

The following is the selection process of the linear ceramic axis, which can be used as the benchmark for selection.

The precision is determined by comparing with the required life, the precision grade is selected, the type suitable for the use condition is selected from the classification table of the linear ceramic shaft, and the selection type is tentative for its approximate size.

Strength check of ceramic axis (LM axis strength check)

● Tentative ceramic axle diameter

● Tentative length of ceramic shaft

● Fixing method of ceramic shaft

● Allowable load of ceramic shaft

● Ceramic shaft displacement (flexure)

The load is calculated, and then the service life is predicted by the life calculation formula to get the rated life.

● Stroke length: LS

Low speed: V

● Load bearing size: W

● Installation space

● Usage frequency (working cycle)

● Required life

● Dimensions (number of bearing sleeves, number of shafts, span)

● Installation method

● Usage environment

Low accuracy

Set conditions of use

● Determine lubricant

● Determine the lubrication method

● Determine the surface treatment

● Dustproof design

Choose according to the environment you use
