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:
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.

Frequently Asked Questions
Our industrial rollers are manufactured from premium-grade 42CrMo alloy steel, which provides an exceptional balance of high strength, toughness, and superior wear resistance under heavy cyclic loads.
The rollers undergo a strict 5-stage manufacturing process, including bulk heat treatment and induction surface hardening. This achieves a surface hardness of HRC 50-55 (exceeding 800HV) with a controlled depth to ensure a highly wear-resistant outer layer and an impact-absorbing core.
These rollers are produced in strict compliance with the GB/T12361-2016 manufacturing standard. Additionally, all critical dimensions are held to tight tolerances in accordance with ISO 286 standards.
They are ideally suited for demanding mechanical manufacturing applications, particularly in rotary forging, tube sizing, profile rolling systems, and other metal forming operations.
Yes. We provide complete technical support for installation, material selection, and sizing to ensure the rollers align perfectly with your machinery parameters and operational requirements.
