Pit Type Annealing Furnace For Bearing Steel

Pit Type Annealing Furnace Parameters

Furnace dimensions and operating conditions are configured according to bearing steel products, batch weight and required annealing cycle.

Bearing Steel Products for Pit Annealing

The furnace can accommodate bearing steel in different forms before turning, forging, grinding or other manufacturing operations.

• Bearing steel wire and wire coils
• Bearing steel bars
• Bearing rings before machining
• Ring blanks
• Forged bearing components
• Bearing steel parts requiring pre-machining annealing

✅ For coil and batch-loaded materials, the pit furnace structure provides a practical arrangement for treating larger quantities without continuous belt transportation.

Why Anneal Bearing Steel Before Machining?

Bearing steel is often annealed before precision manufacturing to make the material easier to process and prepare a more suitable internal structure.

Lower Material Hardness

Annealing reduces hardness to provide better machinability during turning, cutting and forming.

Improve Machining Conditions

A suitable annealed structure can reduce cutting difficulty and improve tool working conditions.

Prepare for Subsequent Heat Treatment

The material condition after annealing provides a more controlled starting point for later hardening processes.

Relieve Processing Stress

Annealing can help reduce residual stress introduced during previous manufacturing stages.

Support Dimensional Consistency

Controlled heating and cooling help reduce unwanted changes during subsequent machining operations.
