Abstract
PURPOSE:To reduce dynamic torque under low temperatures and to improve lubricity and abrasion resistance by arranging fluorocarbon oil having dynamic viscosity of 7-20cSt under the temperature of 40 deg.C and mixed with molybdenum disulfide between the bearing face of a bearing member and the receiving face of shaft body where a dynamic pressure generating groove is made in at least one of them. CONSTITUTION:A thrust receiving member 53 is secured to one end of inner circumferential face of a housing 40 and a radial bearing face 55 formed with a herring bone type dynamic pressure generating groove is provided on the inner circumferential face with an inner circumferential groove 59 being held between them so as to constitute a bearing member 40. Lubricant produced by mixing perfluoro-polyether oil having dynamic viscosity of 7-20cSt under temperature of 40 deg.C with molybdenum disulfide is employed. Consequently, dynamic torque under low temperature can be reduced, good lubricity can be held for long term and abrasion resistance can be improved.
