摘要： A non-contact plastic or rubber seal disk for bearings with improved sealing performance, which can be thrust into the seal groove of the outer ring concentrically with the bearing, with the bearing axis as center, without difficulty and so tightly as to prevent enclosed lubricant from leaking out, with no undesirable force working on the seal disk in service. The seal disk has a peripheral portion to be caught in a ring-shaped seal groove with a U-shaped section, with the peripheral portion of the seal disk in elastic contact with the inner inside wall and the outer inside wall of the groove. The seal groove is formed inside each outer ring, that is, at each end portion of the inside wall of the outer ring of the bearing and comprises an inner inside wall perpendicular to the axis of the bearing, a bottom wall, and an open-out-formed outer inside wall. The seal disk is so configured as to provide a very narrow gap between the bore wall of the seal disk and the inner ring of the bearing. The seal disk is provided with, on the face of the peripheral portion thereof, a ring-shaped thin projection that comes into contact, in a bent form, with the outer inside wall of the seal groove.

摘要： In a bearing having inner and outer rings concentrically disposed about a bearing axis, the outer ring is provided with an annular mounting groove in an inner surface facing the axis for receiving a shield plate. The shield plate is an annular disk-like plate having a central opening for receiving the inner ring as the shield plate is mounted between the rings. The shield plate has an annular generally V-shaped groove in a surface facing in the axial direction, the groove being bounded on the outer circumferential side by a first portion of the plate having a nearly triangular shape, and bounded on the inner circumferential side by a second portion of the plate. The first portion of the plate has a thickness in the radial direction which is 1/2 to 1/6 the thickness of the second portion, and a height in the axial direction which is 1/2 to 1/5 the thickness of the second portion. Variations in the depth of the mounting groove occurring during formation of the outer ring are absorbed by variations in the deformation of the first portion of the shield plate so that the shield plate lies normal to the bearing axis and the outer ring is not deformed.

摘要： A retainer for ball bearings includes mating plastic members (4,5) having undulating shape and adapted to accommodate a plurality of balls (3) therebetween. One of the mating plastic members (4) has a mating edge provided with recesses (9) formed therein adapted to accommodate corresponding protrusions (10) formed on the other mating plastic member (5). The plastic members (4,5) are secured together, preferably by ultrasonic welding.
