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.

Frequently Asked Questions
What material are the rollers made of and what are its benefits?
The rollers are manufactured from premium 42CrMo alloy steel. This material provides an optimal balance of high outer surface hardness (HRC 50-55) and an impact-absorbing core, ensuring high resistance to deformation and wear under heavy cyclic loads.
What manufacturing standards do these rollers comply with?
Our rollers are produced in strict compliance with the GB/T12361-2016 manufacturing standard and meet ISO 286 tolerance standards for critical dimensions.
What is the production process for these precision rollers?
We employ a rigorous 5-stage production process: forging, rough machining, heat treatment, secondary rough machining, precision machining (including induction hardening with depth control), and final threaded hole tapping.
In which applications are these rollers typically used?
These heavy-duty rollers are ideal for mechanical manufacturing applications, particularly within rotary forging, tube sizing, and profile rolling systems.
Are these rollers resistant to harsh operating environments?
Yes. The rollers feature strong acid and alkali resistance, high temperature resistance, and a wear-resistant surface (>800HV), enabling them to deliver a 30% longer service life in continuous production environments.
