Alloy steel forged bearing ring is a very popular spare part for bearing industry, it will choose excellent alloy steel raw material and be forged.

According to its size , we choose different forging procedure :

1. small size  bearing ring    ( size is upto 300mm )  , mold die forging 

2. middle size bearing ring  ( size is upto 800mm )  ,   open die forging 

3. large size bearing ring      (size is upto  2500mm ),   ring rolling 

Its size range following:

Max diameter: 2500mm

Bearing ring 34CrNiMo6 chemical specification :

（C）：0.30 - 0.38%      （Si）：≤0.40%              （Mn）：0.50 - 0.80%

（P）：≤0.035%         （S）：≤0.035%

（Cr）：1.30 - 1.70%  （Ni）：1.30 - 1.70%        （Mo）：0.15 - 0.30%

Bearing ring 34CrNiMo6 mechanical property 

After quenching and tempering treatment, the hardness is 36-40HRC, 

the tensile strength σ b is 1100MPa, the elongation rate δ is 12%, .

In terms of comprehensive performance

High strength: It has high tensile strength and is suitable for manufacturing parts that can withstand high loads.

High toughness: able to maintain stability under impact or vibration loads, with good impact resistance.

Good wear resistance: It can be used to manufacture parts that require resistance to wear and friction, and has good wear resistance and tear resistance under quenching and tempering conditions.

Good fatigue resistance: able to maintain stability under long-term cyclic loading.

Good corrosion resistance: can be applied to the manufacturing of mechanical components that require a certain degree of corrosion resistance.

Delivery condition:

1. Forged + annealing + black surface

2. Forged + annealing + turning 

3. Forged + quenching /tempering + black surface

4. Forged + quenching /tempering + turning
