Abstract
A double cup for a tapered roller being has a concave intervening surface between the small diameter ends of its tapered raceways. The cup is produced by roll forming a tubular blank at ambient temperature into a ring form having the raceways and the concave intervening surface. The presence of the concave intervening surface leaves only a shallow discontinuity in the exterior surface of the ring form, and that discontinuity is machined away with the removal of only a minimal amount of stock. The cup weighs less than cups with straight intervening surfaces.
