The Outer Ring is one of the main components of a standard bearing, together with the other two components, which are the inner rings and the balls. The Outer Ring is the fixed part of the bearing and the inner ring is rotating along the axis.
The Outer Ring is the larger of the two bearing rings. On the outer ring, there is a groove on its inside diameter to form a pathway for the balls. The outer ring surface also has the same high precision finish as the inner ring. The outer ring is usually held stationary.
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.
