A thrust plug that performs the functions of both (i) reversibly capping an end of a length of pipe, a fitting, or the like and (ii) providing a surface against which a concrete thrust block can be cast, thereby facilitating thrust blocking. The thrust plug of the present invention comprises a plug affixed to a base for engagement with a thrust block and against which a concrete thrust block can be directly cast.

A thrust sliding bearing includes an upper casing having a polyacetal resin-made flat annular surface and a lower casing superposed on the upper casing so as to be rotatable about an axis of the upper casing and having a polyacetal resin-made annular surface opposing the annular surface of the upper casing.

A thrust section for use above a motor preferably includes a housing, a thrust shaft, a thrust runner connected to the thrust shaft, a thrust bearing connected to the housing, and a motor lead guard. The motor is preferably positioned above a pump assembly. The thrust runner and thrust bearing prevent upward movement of the shaft.

A thrust washer (9) for planet gears (6) of a planetary gearbox is provided that is made form a tempered, cold rolled strip having a flatness less than or equal to 0.03 mm, and a hardness ranging from 370 to 580 HV. The thrust washer (9) can be produced in a particularly cost effective manner by making it from an appropriate initial stock having the desired final properties.

A thrust bearing assembly in which each thrust pad is individually mounted on a deflection element. An embodiment of the invention comprises a rotating bearing runner having a wear resistant face and a stationary bearing carrier defining a plurality of cavities disposed annularly around the carrier. A deflection element, such as a Belleville washer, is disposed in a cavity of the plurality of cavities and a pad is disposed over the deflection element. The pad is at least partially disposed withi...

The thrust return mechanism (4) is intended for a thrust return pedal. It includes an electric motor (28) for the positioning of a control member (30) by the intermediary of transmission elements. The transmission elements include at least one cable (48, 52) of which one end is fixed to a first pulley (42, 54) and which is then wound around a second pulley (40, 50) and of which the second end is fixed on the first pulley (42, 54).

A thrust bearing assembly is described that includes a self-aligning thrust bearing used in fluid thrust assemblies where the thrust may become unevenly distributed, e.g. in a water jet propulsion unit. The thrust bearing is designed to be lubricated by water and to be self-aligning against uneven thrust forces applied to it. The self-alignment is achieved by the design of the bearing, which is in the form of an annular multi-layer plate. The bearing plate comprises a metallic central core layer...

A thrust sliding bearing (1) includes an upper casing (3) having an annular surface (2); an annular lower casing (5) which is superposed on the upper casing (3) so as to be rotatable about an axis (0) of the upper casing (3) and has an annular surface (4) opposed to the annular surface (2) of the upper casing (3); and an annular thrust sliding bearing piece (6) and an elastic ring (7) which are superposed on top of each other and are interposed between the annular surfaces (2) and (4).

A manually and/or fluid-pressure operated rotary actuator is coupled with a power screw in a compact assembly to produce large linear thrust. The actuator is operated in both directions by fluid pressure or in one direction by fluid pressure and in the other by spring energy, or by fluid pressure alone or in combination with manually applied force. The actuator has a cylindrical housing, a cylindrical reaction member inside of the housing, a cylindrical piston partially covering the reaction mem...

There is provided a roller thrust bearing providing reduced differential slip, free of significant friction and wear, and providing increased longevity against flaking. The present invention provides a thrust bearing in the form of a roller thrust bearing including at least two radially arranged rows of rollers and a cage holding the rollers, the rollers including at least one roller crowned.
