ABSTRACT:
A bearing wheel body forming apparatus comprising a wheel body forming roller, a mandrel and a support roller all supported rotatably in parallel with pressing force also applied to the forming roller and support roller, wherein the forming roller and support roller are driven via a one way clutch and a free coupling. When the circumferential speed of the outer circumference of the wheel body being formed is greater than the circumferential speed of the driven surface of the mandrel, the forming roller is set free by the free coupling so that at the forming surface of the forming roller the speed will be the same as the outer circumferential speed of the work body. In this manner, substantially the same speed of working is used for the entire wheel body and thus prevents uneven forming, and thus prevents vibrations caused by uneven forming.
