The mechanical performance of a bearing outer ring refers to its ability to withstand various loads and stresses during operation. It is a crucial factor in determining the overall durability and reliability of the bearing.
The outer ring of needle roller bearing with groove is a thin stamping outer ring, which has the characteristics of low section height and high load bearing capacity. The outer ring of this kind of bearing is usually made of high quality material and is finished and polished to ensure high precision and smoothness. The outer ring is provided with grooves which are designed to help improve the performance and service life of the bearing .
Overall, the mechanical performance of a bearing outer ring is critical to the performance and longevity of the bearing, making it an important consideration in the design and selection of bearings for any application.
Many years of know-how producing outer rings using cold rolling process
Using the cold rolling process we save raw material up to 20% if compared to standard process
Fiber flow are aligned to balls raceways due to cold rolling process
Using the cold rolling process, the stock material is lower than standard process
Parts are through hardening and ready for grinding
Surface treatment:Plain finish,ZINC plated, color zinc or as your requirement
Application:Used in petroleum, chemical industry, aerospace, paper, automobile, packaging machinery,
decoration, railings and other engineering, hardware processing, ships, power plants and other industries.
