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.

Ultra Linear Bearing "U Series"

Ultra Linear Bearing "U Series"

High reliability under harsh moment loads! Significantly reduce maintenance costs.

Under usage conditions where moment loads are applied, such as vertical use with cantilever support, several times to over a dozen times the load acts on the linear bearings, which can lead to early failure. To address this issue, the 'U Ultra Series' has been developed through years of research. It is compatible with almost all of our linear bearing series, and since the outer dimensions remain unchanged, it allows for an ultra-long lifespan that is 18.5 times longer than conventional products, leveraging our accumulated experience and processing technology without the need for design changes. 【Features】 ■ Achieves an ultra-long lifespan 18.5 times longer than conventional products ■ Reliable performance even under harsh usage conditions ■ Compatible with almost all of our linear bearing series ■ No design changes required as outer dimensions remain the same *For more details, please refer to the PDF document or feel free to contact us.

Maintenance-free linear bearing "MF Series"

Maintenance-free linear bearing "MF Series"

No maintenance required and 3.7 times longer lifespan! Triple shield structure prevents foreign matter contamination.

The "Ozack MF Series" is a linear bearing that eliminates the need for grease replenishment, thereby reducing maintenance costs. It features special seals all around, excelling in dust and oil supply, and the newly developed seal structure significantly reduces grease leakage. When combined with CG (clean-compatible grease), it is suitable for clean environments; with VG (vacuum grease), it is suitable for vacuum environments; with HG (high-temperature and low-temperature grease), it is suitable for high and low-temperature environments; and with FG (food equipment grease), it is ideal for use in food equipment. 【Features】 ■ The newly developed seal structure significantly prevents grease leakage. ■ Lubrication performance is improved and can be maintained over a long period. ■ Rust-resistant types are standardized, making them suitable for use in corrosive environments. ■ The special seals have functions for retaining and supplying lubricating oil, as well as preventing foreign object intrusion. ■ The incorporation of grease and improved sealing performance results in quieter operation. *For more details, please refer to the PDF materials or feel free to contact us.
