| High Light | 42CrMo High-Strength Shafts ，42CrMo Roller Shafts ，Alloy Steel Roll Shafts | ||
Roller shafts that bend under load or wear quickly change the roll gap and profile, so the mill drifts out of tolerance and produces inconsistent tube over time.
Ordinary carbon steel shafts deflect under forming load and wear at the bearing and roller seats, gradually altering roll alignment and tube geometry during long runs.
The ZY16 roller shafts are made from 42CrMo high-strength alloy steel, heat-treated for hardness and toughness, so they resist deflection and wear under sustained forming load. Stable shaft geometry keeps roll gaps consistent, extending tooling life and maintaining Φ8-18mm tube tolerance over long, high-speed campaigns.

42CrMo shafts resist deflection and wear under sustained load, so roll gaps stay where they were set. This keeps Φ8-18mm tube within tolerance across long, high-speed campaigns and extends tooling life, reducing the roll corrections and downtime that eat into output. Heat-treated for hardness and toughness, the shafts balance rigidity with shock resistance, so they survive both continuous running and the occasional overload without bending or cracking. That stability means the tube coming off the line at the end of a long campaign still measures the same as the first coil.
For Φ8-18mm tube production where consistent geometry over long, high-speed runs and long tooling life reduce downtime and rework.
Choose this mill when you run long production campaigns and need stable geometry with minimal roll adjustment. 42CrMo shafts pair with double-radius rollers for the best precision.
High-volume tube runs, high-speed production, and precision tube where dimensional drift and frequent roll adjustment are unacceptable.
42CrMo alloy steel is heat-treated for strength and wear resistance, so shafts resist deflection and keep roll geometry stable.
Yes, wear-resistant shafts reduce roll movement and drift, extending the life of both shafts and rollers.
Normal lubrication and periodic gap checks; the 42CrMo shafts need less frequent correction than carbon steel shafts.
Yes, 42CrMo high-strength shafts are standard, paired with double-radius rollers for stable high-speed forming.
Less often than with carbon steel shafts, because 42CrMo resists deflection; periodic checks and lubrication are usually enough.
Standard mill bearing grease is used; we provide a lubrication schedule with the commissioning documents.
