As a precision mechanical component, the outer ring of a roller bearing plays a crucial role in ensuring the stability and durability of the bearing. Made from high-quality steel, the outer ring is carefully designed and manufactured to provide exceptional strength and rigidity, enabling it to withstand heavy loads and prolonged use. Additionally, it is often treated with special coatings or finishes to enhance its resistance to corrosion and wear, further prolonging its service life. Overall, the outer ring of a roller bearing is a critical component that contributes to the efficient and reliable operation of a wide range of machinery and equipment.
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.
