A screw conveyor is provided for lifting a sludge from a collection point. The conveyor includes a lower bearing assembly having a post with a thrust bearing attached to the top, which can be inserted in a socket in the shaft component of the screw. The base of the post is attached to a plate, and the plate can be bolted to the intake end of the tube component of the conveyor. The inner bearing assembly and the intake end of the shaft of the screw are contained within the interior of the tube, such that a seal between the shaft and the plate, which serves as an end cap of the tube, is not required. In an alternative embodiment of the invention, the relative positions of the post and socket can be reversed, with the socket attached to the plate to the intake end of the tube, and the post attached to the shaft component of the screw.

A bearing assembly for supporting a rotor in a fixed housing includes multiple slide bearing segments, each having a slide bearing body supported against a sliding surface. In the region of each slide bearing segment, the bearing clearance between the respective slide bearing body and the sliding surface is adjustable by an adjustment screw, each adjustment screw having an outer thread via which the screw can be screwed into a recess having an inner thread, each adjustment screw having a groove delimited on both sides by adjustment screw sections. A clamping screw extends through the adjustment screw sections and also through the groove, the adjustment screw sections can be clamped by the clamping screw, whereby each adjustment screw can be secured in the respective recess.

A bearing including: a sidewall including a substrate and a low friction layer overlying the substrate, where the sidewall further includes: an unformed section; at least one slot in the unformed section; and at least one protrusion extending from the unformed section forming a generally concave or convex cross-sectional shape in the sidewall.

Bearings assemblies are provided that include polycrystalline diamond bearing surfaces that are engaged with opposing, metal bearing surfaces that include more than trace amounts of diamond solvent-catalyst. In the bearings, the opposing bearing surface is slidingly engaged with the polycrystalline diamond bearing surface along a diamond contact area of the polycrystalline diamond bearing surface, and the polycrystalline diamond bearing surface is a continuous surface along the diamond contact area. Also provided are methods of making and using the bearing assemblies.

A hydrodynamic bearing structure is provided. The hydrodynamic bearing structure includes a bearing body, a shaft hole, at least one oil guide groove assembly, at least one air escape unit, and a recess. The shaft hole is formed in the bearing body and penetrates through the bearing body to two ends of the bearing body. The oil guide groove assembly is formed on an inner wall of the shaft hole. The air escape unit is disposed on an outer wall of the bearing body, and has a groove or a tangent plane. The recess is formed at one of the two ends (e.g., a bottom end or a top end) of the bearing body. The recess is spatially communicated with the air escape unit so that an exhaust passage is formed between an axis of the bearing structure and the air escape unit.

A bush assembly configured to be disposed between a first component and a second component movably coupled to the first component, the bush assembly comprising a first bush portion comprising a self-lubricating material; and a second bush portion, the second bush portion having greater electrical conductivity than the first bush portion, wherein the second bush portion provides a conductive path between the first component and the second component.
