•Cage

In daily operations, cage will be subjected not only to mechanical action from friction, tension and inertial force, but to chemical reaction from lubricants, additives, solvents or coolants. Therefore, design and materials of cage are very inportant for its performance and the reliability of bearing in usage.

ZYSL Bearings offers the following kinds of cages for deep groove ball bearings:

 

•Materials of Bearings

Materials for bearing rings and parts largely determine the bearing's performance and life. ZYSL Bearings puts more efforts to select materials for bearing ring and part suppliers in a rigorous manner.

Materials and components of bearing rings for ZYSL Bearings are provided by the world's top suppliers,especially for serving bearing manufacturers, fundamentally solving the issue that our bearings lag behind imported bearings in terms of materials for a long time.

ZYSL Bearings boasts a set of strict incoming goods inspection system. Before being put into storage, every batch of steels and parts is under systemic 

inspection, including analysis of material composition, metallographic analysis, accuracy check, assembly test, etc.

 

•Materials for Bearing Ring and Roller Body

Bearing ring and roller body are mainly made of high-Cr bearing steel. Listed below are compositions of material for bearing ring and roller body.

•Material of cages

Material of cages need good wear resistance, stable size and metal strength. Therefore, operation environment should be mainly considered in selection of material of cages.

 

Cold-rolled Steel Cage

These light cages hold a high strength with reduced friction and wear in an effective way after surface treatment. The following table covers compositions of material for cold-rolled steel sheet.

Brass Cage

Brass cage is adopted in small and medium bearings. However, brass cage is not suitable for compressors with ammonia cooling due to potential seasonal cracking of brass. It is recommended to replace it with iron cage.

 

Nylon cage

According to the type and usage of bearings, nylon cages are widely adopted, but they are inappropriate for environments where the temperature is above 120℃ or below 40 ℃. Most of cast molding cages adopt nylon PA66 material, with or without glass fiber reinforcement whose advantage is a good combination of strength and elasticity.

 

•Materials for Dust Shield and Sealed ring

 

Material for dust shield

 

ZYSL Bearings use cold-rolled tin plate as the standard mateiral for dust shields, but also use stainless steel of AISI300 specification sometimes.

 

Material for seal ring

Seal rings are mainly made for high temperature, fluoro rubbers and silicon rubbers are widely used as well.

 

Applications:

Deep groove ball bearings can be used for transmission, instrumentation, motors, appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, engineering machinery , roller skate style , yo-yo , precision instruments, low noise motors, automobiles , motorcycles vehicles.
