IPC: F16C33/58
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To hold down a current value in the bearing to the minimum by forming an insulating layer in either of an outer ring outside diametral surface or an inner ring inside diametral surface or both as well as at least either side of an outer ring or an inner ring integrally or separately with or from a seal, and making this insulating layer into the specified dielectric constant of a synthetic resin, thermoplastic elastomer and synthetic rubber. SOLUTION: An insulating layer 5 is formed in both the whole circumferential areas on an outer ring outside diametral surface 2a and a side face 2b, while it is further extended from an insulating layer part 5b being situated at the side of the side face 2b and made into a ring form integrally formed with a seal 6. This insulating layer 5 consists of synthetic resin, thermoplastic elastomer or synthetic rubber, and in this case it is recommended that such one whose dielectric constant is less than 7 (1 kHz) is desirable. This seal 6 is made of the same material as that of the insulating layer 5, and it is composed of a soft part 6a integrally formed and a core 6b consisting of metal or synthetic resin.  With this constitution, an electric current flowing in a gap between both inner and outer rings of a bearing is checkable to the minimum, and further any possible electrolytic corrosion on both inner and outer raceway surfaces or a roller rolling surface is thus obviable.
