Roller - Machinery manufacturing

1. Manufacturing standard: GB/T12361-2016;

2. Pressure level: not under pressure

3. Product material: 42CrMo

4. Production process: forging, rough machining, heat treatment, secondary rough machining, precision machining, tapping.

5. Product features: Strong acid and alkali resistance, high temperature resistance, long service life, smooth surface, high quenching hardness on the outer surface, high resistance to deformation, and strong resistance to yield

6. Scope of application: Mechanical manufacturing.

Crafted from premium 42CrMo alloy steel, these heavy-duty rollers deliver exceptional hardness (HRC 50-55 post surface hardening) while maintaining superior fracture toughness – an optimal balance for high-stress metal forming operations. Through our rigorously controlled 5-stage manufacturing process (rough machining → bulk heat treatment → secondary precision shaping → induction hardening with depth control → threaded hole finishing), each roller achieves:

Uniform microstructure eliminating stress concentration

Wear-resistant surface (>800HV) with impact-absorbing core

True-running geometry (±0.02mm concentricity)

Anti-spalling performance under cyclic loading

Ideal for rotary forging, tube sizing, and profile rolling systems, these components consistently outperform standard rollers with 30% longer service life in continuous production environments. All critical dimensions comply with ISO 286 tolerance standards.
