    Abstract: A grease composition having an apparent viscosity at −30° C. of 5 to 200 Pa·s is sealed in a rolling bearing which retains a plurality of rolling elements between an inner ring and an outer ring in such a way that the rolling elements can freely roll. Thereby, there is provided a rolling bearing which has a satisfactory lubricating performance and generates less abnormal noise even under a low temperature of around −40° C.

    Abstract: A ball screw (1) as a linear motion device according to the invention has retaining pieces (21) each having two concave surfaces (23) facing adjacent ones of rolling elements (9) respectively. Each of the retaining pieces (21) is disposed between adjacent ones of the rolling elements (9). A carbonitrided layer containing residual austenite of 15-40% by volume is provided in the surface layer of each of the rolling elements (9).
