They are High-load, long-duration racing such as circle track, off-road and others that require steel crankshafts. Mains are 1/2" grooved for uncompromised lower shell load capacity. 0.0005 metallurgically enhanced and hardened performance overlay withstands greater loads and better resists surface fatigue. (15-30% greater load capacity than traditional bearings)
