Abstract:
Provided is a grease composition which can be used as a lubricant for roller bearings, exhibits excellent high temperature durability and rust preventive property, and can prevent premature flaking on the rolling surface due to hydrogen embrittlement. A roller bearing  1  is obtained by sealing a grease composition  7  in the periphery of a rolling element  4 , this grease composition  7  is composed of a base oil excluding an ester-based synthetic oil, a thickener, and an additive, the additive contains (a) an alkanolamine and (b) 2,2,4-trimethyl-1,2-dihydroquinoline or a polymer thereof but does not contain an organic sulfonate, and (a) and (b) are contained at from 0.1 to 10 parts by weight with respect to 100 parts by weight of a total amount of the base oil and the thickener, respectively.

Claim (Index 1):
A grease composition comprising:\n a base oil excluding an ester-based synthetic oil; a thickener; and an additive, wherein the additive contains (a) an alkanolamine and (b) a compound represented by the following formula (1) or a polymer of the compound but does not contain an organic sulfonate, wherein (a) and (b) above are contained at from 0.1 to 10 parts by weight with respect to 100 parts by weight of a total amount of the base oil and the thickener, respectively:
