What is the maximum seamless rolled ring size?
Quick answer
Monmet supplies seamless rolled rings across a wide range of tonnages and outside diameters. Ring rolling produces a continuous circumferential grain flow with no weld seam, which is why it is preferred for bearing races, gear blanks, flanges and other circular high-stress components.
Why a rolled ring outperforms
A rolled ring has no weld and no parting line, so there is no metallurgical discontinuity around the circumference. For rotating components under fatigue loading, that removes the most common crack initiation site.
Profiles
Rings can be rolled rectangular or to a contoured profile that reduces machining stock. Contoured rolling is worth evaluating on large diameters where removed material and machining hours dominate the cost.
Related forged forms
Discs, hubs, step-down shafts and bars are supplied from the same forging range, so ring and shaft components for one assembly can be sourced together.
