Precision-Engineered Rollers for Demanding Industrial Applications
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.
