Wall Ball Bearing Sleeve Outer Ball Bearing Rings, also known as bearing sleeves, serve as a protective covering for the outer race of ball bearings. These sleeves play a crucial role in maintaining the integrity and prolonging the lifespan of the bearing by preventing contaminants such as dust, dirt, or debris from entering the bearing assembly. Additionally, they can help distribute loads more evenly, reduce friction, and provide support to the bearing during installation and operation. Wall Ball Bearing Sleeve Outer Ball Bearing Rings are commonly used in various applications including automotive, industrial, and construction machinery.
Why the Outer Ring for Bearing from us:
-
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
Application:Used in petroleum, chemical industry, aerospace, paper, automobile, packaging machinery,
decoration, railings and other engineering, hardware processing, ships, power plants and other industries.
