Seamless Rolled Rings
Any ring that rotates under load — a bearing race, a slew ring, a gear rim — needs grain running continuously around its circumference. Ring rolling is the only process that delivers that structure without a weld.

Applications That Demand Seamless
Bearing inner and outer races, gear rims, slew rings for cranes and excavators, flange rings, coupling rings and pressure vessel rings. In each, hoop stress and rotating fatigue would find a weld and exploit it.
- Bearing races and gear rims
- Slew and turntable rings
- Flange and coupling rings
- Pressure vessel rings
Contoured Profiles
Profiled mandrels roll a near-net cross-section — a race groove pre-form, a stepped flange profile — cutting machining time and material loss substantially against rolling a plain rectangle and turning the shape into it.
Heat Treatment and Finishing
Rings are normalised or quenched and tempered per grade, then turned on CNC lathes with concentricity, flatness and parallelism verified before dispatch.
People also ask
Can you roll contoured ring profiles?
Yes, profiled mandrels produce near-net sections such as race groove pre-forms, cutting downstream machining and material loss.
What ring wall thickness can you produce?
From 20 mm upward, at diameters from 100 mm to 1,200 mm and heights to 300 mm.

Questions Answered
What makes a rolled ring better than a welded one?
+
No weld, no heat-affected zone and continuous circumferential grain — the three things that decide fatigue life under rotating hoop stress.
Can you roll contoured profiles?
+
Yes, profiled mandrels produce near-net sections that cut downstream machining.
What ring sizes do you produce?
+
100 mm to 1,200 mm outside diameter, heights to 300 mm.
Are rings supplied machined?
+
Proof machined or fully finished to drawing, with concentricity and flatness reported.
