摘要： A concave surface 60 is formed in an outer peripheral surface of each of pillar portions 26 of a cage 40. A plurality of recesses 42, 43, 52 and 53 are formed in outer peripheral surfaces of annular portions 24 and 25 of the cage 40. There are provided passageways 46, 47, 56 and 57 communicating respectively with the recesses 42, 43, 52 and 53. An axially-outer end of each of the passageways 46, 47, 56 and 57 is open to an axial inner end face of the annular portion 24, 25 or to the concave surface 60 of the pillar portion 26.

摘要： An inventive ball bearing retainer (4) is entirely composed of a resin composition, and has pocket surfaces (6) for retaining balls (5) and projections (8) provided on the pocket surfaces (6) and containing a solid lubricant (CB). A ball bearing (1) incorporates the ball bearing retainer (4). By the effect of the solid lubricant (CB), the projections (8) are less liable to be worn out in a short period particularly when the ball bearing (1) is used in a higher temperature environment. The projections (8) define clearances between the balls (5) and the pocket surfaces (6), making it possible to maintain the effect of preventing noise, increase in the torque of the ball bearing (1), reduction of the service life of a lubricant and the like for a longer period of time.

摘要： Disclosed is a bearing retainer made of a resin composition comprising a polyamide resin which has a repeating unit represented by the formula (1) below and a repeating unit represented by the formula (2) below in which formulae R1 and R2 represent three kinds of groups, namely a p-phenylene group, a linear alkylene group having 6-10 carbon atoms, and a branched chain alkylene group having 6-10 carbon atoms. Such a bearing retainer can be used in various applications since it has sufficiently good resistance to a wider variety of lubricating oils in a wider temperature range when compared with conventional resin hearing retainers.

摘要： A bearing retainer, which is molded with a resin composition comprising a polyphenylene sulfide and a second resin having a higher deflection temperature under a load at 1.8 MPa than polyphenylene sulfide. The bearing retainer exhibits high heat resistance, chemical resistance, oil resistance, strength at a high temperature, and the like, being comparable to those of a conventional bearing retainer made of polyether ether ketone and further exhibits higher accuracy in dimension and shape and can be produced at a lower cost, as compared to a bearing retainer made of polyether ether ketone. It is preferred that the above second resin is a resin having a flexural modulus higher than that of polyphenylene sulfide and that a resin composition contains carbon fiber as a reinforcing fiber.
