    摘要: A linear motion device has: a linear motion body externally fitted onto a shaft and making a relative linear motion along the shaft; a plurality of balls retained in a rolling element groove formed in an inner surface of the linear motion body, and rolling between the rolling element groove and the shaft; separators interposed among the balls; and a circulating path formed in the linear motion body and for circulating the balls from one end side of the rolling element groove to the other end side thereof; wherein the linear motion device is charged with grease containing base oil which is 220-395 in worked penetration defined by JIS K2220 and 50-500 mm2/s in kinematic viscosity at 40° C.

    摘要: A grease which comprises a base oil containing at least 50% by mass of a diester compound having a total carbon number of 28 to 40 and represented by the general formula (I): R1OOC—(R2)n—COOR3  (I) wherein R1 and R3 each independently represent a C4 to C20 monovalent aliphatic hydrocarbon group, R2 represents a C1 to C20 divalent hydrocarbon group and n is 0 or 1. The grease is excellent in both low-temperature performance and high-temperature performance and has low oil separation tendency even under high centrifugal force (acceleration). In particular, when the grease is used in a rotational transmission device having a built-in one-way clutch, the grease can provide satisfactory clutch engagement property (intermeshing ability) at low temperatures and a prolonged bearing life at high temperatures and is less apt to cause oil separation under high centrifugal force.
