Abstract: In the rolling device of the present invention, a grease composition is enclosed which contains a base oil having a kinematic viscosity of 15 to 80 mm2/s at 40° C. and, as a thickener, a mixture of lithium 12-hydroxystearate and a lithium fatty acid having a carbon number of 6 to 12, and has a dropping point of 190 to 240° C. and a yield stress of 1.2 to 5 kPa. Accordingly, the torque is reduced and the acoustic life is improved.
