Further expand the product lineup and technical information
NTN has released a complete revised "Ball and Roller Bearing Catalog" so that customers can make full use of our rolling bearing technical information and know-how.
In this full revision, we reviewed the basic dynamic load rating* 1, which is the basis for calculating the life of rolling bearings based on our accumulated bearing life data over the years, and lists the required fatigue load limit for each model of ISO The revised rating life specified in the standard and JIS*2. * 3 .
In addition, we have expanded the product lineup of the ULTAGE * 4 series, which is the world's highest level in our bearing series, to meet the diverse needs of customers.
In addition, we have enhanced the technical information by greatly increasing the number of pages on technical instructions (such as how to select and handle bearings and how to design peripheral components). The size was also changed from the traditional A4 to A5 to make it easier to handle, and a step-by-step index was applied so that customers can open the page immediately.
Not only choose our products, but also use this revised catalog to learn about ball and roller bearings. NTN NUTR203X bearings online , pls click here :
Indicates the dynamic load capacity of the rolling bearing. This is the basis for calculating the life of the rolling bearing and the constant load, which makes the basic rating life of one million revolutions.
The rated life of the bearing has been modified to achieve 90% or higher reliability or higher combinations, fatigue load limits, lubricant contamination and specific working conditions.
The revised fatigue load limit and basic dynamic load rating are not included in the dedicated catalog. It is planned to be included in order for each catalog revision.
ULTAGE is the name of NTN's new generation of bearing series with the highest global standards. It exhibits "ULTIMATE" performance on any type of "STAGE".
