Technical Data: Guidance on Calculating Basic Dynamic Load Ratings for Linear Bearings and Linear Guides

Technical Data: Guidance on Calculating Basic Dynamic Load Ratings for Linear Bearings and Linear Guides

Here is the formula for calculating the basic dynamic load rating of linear ball bearings.

In ISO, the basic dynamic load rating calculation formula for general rolling bearings uses the "Lundberg-Plamgren (1947)" theory, and similarly, experimental formulas are used for linear ball bearings as well. Therefore, this document includes the "calculation formula for basic dynamic load ratings of linear bearings and linear guides." It also introduces the "simplified ISO basic dynamic load rating calculation formula" and the "basic static load ratings for ball bushes and ball guides." Please make use of it. 【Overview】 ■ Guidance for calculating the basic dynamic load ratings (ISO) of linear bearings and linear guides ■ Simplified ISO basic dynamic load rating calculation formula ISO14728-1 (2004) ■ Basic static load ratings for ball bushes and ball guides ISO14728-2 (2004) *For more details, please refer to the PDF document or feel free to contact us.
