In a rolling bearing structured such that a plurality of rolling elements are respectively held between inner and outer rings by a retainer, grease is sealed in by a seal, a rotary body with the outer ring fitted therewith and a shaft with the inner ring fitted therewith can be connected together by a clutch mechanism and, when the rotary body and shaft are connected together by the clutch mechanism, the rolling bearing can be used on receiving a rotation load while the relative rotation between...

A linear bearing includes a linear guide on which a carriage is translationally movable, a plurality of balls between the linear guide and carriage located in a contact area between the linear guide and the carriage on a straight line, ball deflection sections each adjoining one end of the line outside the contact area, and a ball return section, with the balls being adapted to continuously revolve along the line between the linear guide and the carriage, the ball deflection sections and the bal...

In a bearing device in which a free end of a shaft body to which a rolling bearing is mounted is bent outward in its radial direction into a shape to be pushed against an end face of an inner ring of the rolling bearing so as to prevent the rolling bearing from falling out, a raceway surface of the inner ring of the rolling bearing is subjected to hardening treatment, and another portion of the inner ring is made of raw material which is not hardened. With this arrangement, the caulked portion f...

A hydraulic bearing includes a supporting bearing, a bearing base, and an annular spring element of elastomeric material interconnecting the supporting base and the bearing base. A working chamber and a compensating chamber are bounded by the supporting bearing and bearing base and filled with damping fluid. A partition having an opening separates the working chamber from the compensating chamber. The opening connects the working chamber and the compensating chamber in a fluid-conducting manner....

A rolling bearing intended for longer life by improving seizure resistance and wear resistance in the circumstance with slip contact or in the circumstance where lubricant tends to be exhausted, which is manufactured by applying carburization or carbonitridation to an Si-added material to disperse and precipitate carbides or carbonitrides containing Si or Si--X (X=one or more of Mn, Mo, and Cr) thereby improving the seizure resistance and the wear resistance by the self-lubrication effect thereo...

A bearing device in which a rolling bearing is fitted on one axial end of a shaft and in which the one axial end of the shaft is caulked to fix the rolling bearing while preventing the same from coming out. The shape of the outer end face of the caulked portion is devised to maximize the resistance to the coming-out by the caulked portion.

With an active magnetic bearing 1 there is a limit to the available rapidity of response to transient loadings upon a target or rotor 4. Thus, in accordance with the present invention, storage devices 25, 125, 225, 35 hold an electrical voltage VS significantly greater than the normal supply voltage V provided by a normal electrical source 22, 32. In such circumstances when a very large transient loading is detected on the bearing 1 a switch 26, 37 discharges the supply voltage VS across the coi...

An intermediate bearing for a driveline of a commercial vehicle has a housing (7) with a stirrup-shaped cross-section. The housing (7) has a fixing face (12) formed of two straight portions (8, 9) and a first arched portion (10). A bearing member (15) is arranged between the portions (8, 9, 10). The bearing member (15) is rubber and is connected to the fixing face (12) by vulcanization. A locking element (23) bridges the space between the two straight portions (8, 9). The locking member (23) is ...

A bearing device in which a rolling bearing is fitted on one axial end of a shaft and in which the one axial end of the shaft is caulked to fix the rolling bearing while preventing the same from coming out. The shape of the outer end face of the caulked portion is devised to maximize the resistance to the coming-out by the caulked portion.

A bearing assembly includes a sleeve bearing (2) having a mating portion (22) and a center bore (20), a shaft (1) disposed in the center bore, and a rotary block (3) mounted on the shaft and being rotatable therewith. A gap exists between the inner circumferential surface of the bearing and the outer circumferential surface of the shaft to allow the shaft to be capable of rotate in the bore without scrapping the bearing. The rotary block includes a mounting portion (30) engaging with the mating ...
