Inner Ring Forging Process

The forging of inner rings involves multiple precision-controlled stages to achieve structural integrity and dimensional accuracy.

  1. Billet Selection and Heating — High-quality alloy or carbon steel billets are cut to the required size and heated uniformly to 1050–1250°C to ensure ideal plasticity and refined grain flow.

  2. Upsetting and Preforming — The heated billet is upset and roughly shaped to achieve the target cross-section and prepare for ring formation.

  3. Piercing (Punching) — A central hole is punched to create a donut-shaped blank. This allows accurate metal flow during the rolling stage.

  4. Ring Rolling — Using advanced ring-rolling mills, the blank is expanded radially and axially to achieve precise wall thickness and diameter control, aligning the grain structure circumferentially.

  5. Heat Treatment — Processes such as normalizing, quenching, and tempering enhance mechanical strength, fatigue resistance, and dimensional stability.

  6. CNC Machining & Inspection — Precision machining (turning, grinding, drilling) ensures tolerance accuracy up to ±0.01 mm. Ultrasonic, hardness, and dimensional inspections guarantee quality and traceability.

This process produces inner rings with excellent concentricity, load-bearing capacity, and fatigue strength.

Key Features of Precision Inner Ring Forgings

Superior Strength and Durability

Our forged inner rings are made from high-strength materials for excellent performance in demanding conditions. The forging process refines the grain flow, improving strength and fatigue resistance—ideal for high-load and rotating parts.
