Linear bearing

Linear bearing

High precision and compact lightweight design! Extremely low noise during movement, providing a smooth environment for the ball!

"Linear bearings" allow for smooth circulation of 4 to 6 rows of balls within a narrow circuit while bearing loads, enabling compact design along with the miniaturization of power sources and drive mechanisms. When used in combination with high-precision "TSK linear shafts," this product provides precise and smooth linear motion, making it possible to reduce the size and weight of machinery. [Features] - Compact design - Compatibility - Low noise - High precision and lightweight - Long lifespan *For more details, please refer to the PDF document or feel free to contact us.

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.
