KUSHALMANI FORGE produces seamless mandrel forged rings and sleeves in a wide range of materials. KUSHALMANI FORGE’s forged rings are used in many industrial applications where high strength, impact resistance and increased fatigue life are required such as bearings, gears, bushings, cylinders, seals, couplings, piping applications, nuts and locking collars. Forged rings can offer great advantages over rings cut from steel plate or bar stock. Forged rings have considerable material cost savings due to the ring being hot formed on a mandrel as opposed to the inside diameter being cut from the plate or bar. Additionally a forged ring can have metallurgical advantages from being forged with a radial or tangential grain flow, not found in rings cut from bar or plate. Furthermore, KUSHALMANI FORGE’s large assortment of saddles and mandrels enable us to forge heavy and thin-walled rings and sleeves. Due to the low tooling cost for forging mandrel rolled rings an sleeves there is no minimum quantity requirements.
