Grease composition for rolling bearing

摘要

A grease composition for rolling bearings is disclosed which contains: (A) 100 parts by weight of a base oil having the kinematic viscosity of 40 to 200 mm<2>/s at 40 DEG C, (B) 5 to 65 parts by weight of an urea thickener, and (C) 0.05 to 10 parts by weight of zinc dithiocarbamate. This grease composition is suitable for application to rolling bearings in electrical components and accessory devices for automotive vehicles, such as alternators, electromagnetic clutches for car air conditioners, idle pulleys, electric fan motors, or the like.
