Processing technology of bearing outer ring

Process flow of bearing outer ring processing: Bearing steel ->Forging ->Annealing ->Turning ->Heat treatment ->Grinding ->Assembly ->Inspection ->Packaging and warehousing

The purpose of forging technology

1. Forming: Control reasonable turning allowance.

2. Obtain a high lifespan forging streamline distribution to ensure bearing life.

3. Obtain the ideal metallographic structure and prepare for annealing and quenching.

The purpose of annealing process

1. Reduce hardness and prepare for machining.

2. Obtain the ideal metallographic structure and prepare for quenching.

3. Provide uniformly distributed residual carbides for finished parts to ensure the wear resistance of bearings.

The purpose of machining

1. Forming

2. Reduce reserve and prepare for grinding.

3. Remove the decarburization layer to ensure the hardness of the finished parts.

Heat treatment - quenching and tempering

1. Improve the hardness of parts to ensure their strength and wear resistance.

2. Obtain the ideal metallographic structure and improve the lifespan of the parts.

The purpose of grinding

1. Improve part accuracy (dimensional and positional accuracy).

2. Improve the surface quality (roughness) of the parts.

Bearing inspection (radial clearance, bearing clearance, vibration value, rotational flexibility, residual magnetism, etc.)
