•Materials of Bearings
Materials for bearing rings and parts largely determine the bearing's performance and life. LYAZ Bearings puts more efforts to select materials for bearing ring and part suppliers in a rigorous manner.
Materials and components of bearing rings for LYAZ 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.
LYAZ 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.
Chemical Composition(%) |
NO. | C | Mn | Si | Cr | S | P | Ni | Cu | HB |
< |
GCr15 DIN 100 GCr6 JIS UJ2 AISI52100 SKF3 | 0.95~1.05 | 0.20~0.4 | 0.15~0.35 | 1.30~1.65 | 0.02 | 0.027 | 0.3 | 0.25 | 170~207 |
Material for bearing ring and roller body mainly consists of high C-Cr bearing steel.
•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.
No. | Chemical Composition% |
JISG 3141 SPCC | C | Si | Mn | P | S | Ni | Cr |
<0.12 | - | <0.5 | <0.04 | 0.045 | - | - |
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 120ºC or below 40 ºC. 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
LYAZ Bearings use cold-rolled tin plate as the standard mateiral for dust shields, but also use stainless steel of AISI-300 specification sometimes.
Material for seal ring
Seal rings are mainly made of NBR. For high temperature, fluoro rubbers and silicon rubbers are widely used as well.

Why Choose LYAZ |
ONLY THE BEST STEEL | ONLY THE BEST RUBBER |
LYAZ only uses the best chrome steel. All Saifan parts that contain metal use an expensive heat treatment process that improves metal strength and performance, also our parts use a higher level of polish to allow the bearing to roll smoother and last longer. | Each Individual component of this part is made with high quality materials. Unlike our competitors Saifan uses only high quality Natural Rubber (75%) and (25%) synthetic Rubber. This means that it is more durable, will last longer, and can handle temperatures from -40 to +140 degrees. The Rubber won't rub off on your hand like the cheap replacement parts offered by competitors | |
