Shape Options
To meet a variety of structural and performance application requirements, we provide flat, tapered, contour, rectangular, and hollow forged rolling rings.
Flat Rolled Rings
- Uniform cross-section, ideal for bearings, flanges, and rotating parts.
- High accuracy and strength under axial and radial loads.
- Used in aerospace, construction, and automotive industries.
Tapered Rolled Rings
- Angled walls fit tapered components in high-stress systems.
- Reduces weight while ensuring structural integrity and alignment.
- Used in turbines, couplings, and transmissions.
Contour Rolled Rings (Profiled Rolled Rings)
- Forged with complex profiles, reducing post-machining.
- Ideal for gear blanks, races, and stepped parts.
- Applied in energy, transport, and defense industries.
Rectangular Rolled Rings
- Square edges provide uniform load distribution.
- Common in hydraulic cylinders and precision housings.
- Offers strength and face alignment in static systems.
