🔩 Full Process Overview:

Selection of high-quality bearing steel (high hardness, wear resistance, toughness)

Heating to 1100°C to enhance plasticity and prevent cracking

Precision billet cutting for strict volume consistency

Hydraulic press forging into dense pancake structure

High-speed punching to create ring preform

Precision ring rolling to achieve final dimensions

Under controlled radial compression, the ring rolling machine gradually reduces wall thickness while expanding bore diameter and outer diameter with high accuracy. The result is a high-density bearing blank with optimized grain flow, excellent fatigue resistance, and superior structural integrity.

This process is ideal for manufacturing:

Bearing inner rings

Bearing outer rings

Automotive bearing rings

Gear blanks

Precision forged rings

If you are looking for high-efficiency, high-precision bearing blank production, this video demonstrates why ring rolling technology is the industry standard.
