Five steps to learn to choose and confirm the lm12uu bearing dimensions

1,431 Published by Dec 27,2018

Usually, when we choose linear bearing, what requirements do we follow? Is it according to the previous size and specification? But when there are different models and different brands, is it still the same? Today, an engineer gives five examples to teach you how to choose lm12uu bearing dimensions, as shown below:

1, determine the size parameters of lm12uu bearing dimensions: in many cases, the size of the inner hole of linear bearing has been specified by the structure of the machine or device. No matter whether the working life, static load safety coefficient and economic efficiency meet the requirements, before the final selection of the rest of the size and structure of linear bearing, must go through dimensional calculation.

2. Static load linear bearing: calculating the static load safety factor Fs is helpful to determine whether the selected linear bearing has enough static load rating. Fs-co /PO where FS static load safety factor, CO rated static load [KN, PO equivalent static load [KN] static load safety factor FS is the safety factor to prevent permanent deformation of rolling parts contact area.

3, dynamic load linear bearing: DIN ISO 281 standard method for linear bearing under dynamic load calculation is the basis of material fatigue failure (pit), calculating formula for life: L10 - L - CPP [106] 110 of them in the name of life [106] C rated dynamic load rating [KNJ P [KN] P index L10 life equivalent dynamic load in 1 million into a unit in the name of life [106] C rated dynamic load rating (KN) P L10 life index in 1 million into a unit in the name of the specified life.

4. Variable load and variable speed: if the dynamic load value and speed of linear bearing change with time, then the equivalent load should be calculated with corresponding consideration. Continuous load and speed curves? I'm going to replace it with a piecewise approximation.

5. Minimum load of linear bearing: too small load and insufficient lubrication will cause the roller to slip and damage the linear bearing. The minimum load coefficient of cage inlet bearing is P/ c-0.02, while the minimum load coefficient of full loaded linear bearing is P/ c-0.04 (equivalent dynamic load, C is rated dynamic load).
