A rolling mill oil film bearing has a sleeve with a tapered interior surface axially received on and rotatably fixed with respect to a tapered section of a roll neck. The sleeve has a cylindrical outer surface journalled for rotation within a bushing contained in a chock, with the chock, bushing and sleeve being axially removable as a unit from the roll neck. The sleeve is machined from a cylindrical forged blank which has a maximum outer diameter equal to the diameter of the sleeve's cylindrica...

A motor fan bracket is molded of a fiber reinforced thermoset polyester. The motor/fan bracket has an annular frame and an annular bearing housing concentric with the frame and supported by inwardly extending arms. The annular bearing housing has a bearing-receiving cavity configured in cross section as an equilateral polygon such that each face of that cavity is tangential to a bearing received therein.

A bearing includes a bushing having an axis and a retainer supporting the bushing. The retainer includes an annular planar portion extending perpendicular to the axis and a plurality of wedge portions projecting radially outward from the annular planar portion in circumferentially spaced relation.

A bearing or bushing retainer comprises two identical, separate segments which are generally c-shaped so as to permit the segments to each be removed from a cylindrical split plastic bearing mounted on a reel toothbar once bolts holding the two segments together are released and the segments moved axially relative to each other so as to disengage respective axially extending tabs of the segments from gaps defined between opposite ends of the segments. The segments have a relatively heavy cross s...

A flange bearing comprises a housing having a body with a reinforcing member encased therein. The housing provides strength and resistance to stress fracturing without the use of heavy materials, such as cast iron, or the use of ribs and recesses which can harbor contaminates. The bearing is preferably lightweight and easily cleaned. Also, a leveler constructed in accordance with the present invention provides similar advantages.

A journal bearing for a high speed surgical drill and/or attachment for rotatably supporting a cutter is made from a polymer of polyimide resin and graphite material and is designed to have a polygon configured bore where there are two point contact of the mating surfaces of the bore walls and cutter's shaft and preferably the bore is square shaped in cross section. This bearing results in a decrease in the envelope size of the support tube and hence, the overall diameter of the surgical instrum...

A bearing assembly for rotatably supporting a capstan shaft of a tape recorder comprises a cylindrical sleeve bearing formed of brass which is loosely supported by a cylindrical casing having internal projections for preventing axial shifting of the brass cylinder relative to the casing. Radial projections from the cylindrical casing are received within axially extending grooves formed on the outer periphery of the brass sleeve bearing to prevent the sleeve from rotating relative to the casing.

A sliding bearing for transmitting radial and axial forces, having an inner and an outer bushing, one of the bushings being provided on both faces thereof with flanges projecting radially against the other bushing, which flanges at least partially embrace the faces of the other bushing thus fixing the other bushing therebetween, and a sliding annular insert having a U-shaped cross-section of antifriction material arranged between said bushings, and having annular projections extending axially ou...

A linear guide unit comprises a hollow elongated member of rectangular cross section, two parallel guide rails mounted on one wall of the elongated member, and at least one runner supported for movement on each of the guide rails. At least one wall of the elongated member other than the one on which the guide rails are mounted has a plurality of T-section grooves, which serve for the fastening of attachments. The runners are U-shaped, straddle the respective guide rails, and are carried on the s...

A bearing device is presented, by which it is possible to rotate a rotation shaft of a motor smoothly at a constant speed without impairing its characteristics even when a load is applied on the rotation shaft from a given direction as when the device is incorporated in video equipment. The bearing device includes a holder designed in a cylindrical shape, a collar unit extending in a peripheral direction near a first end in an axial direction of the holder, fixing units and mounting units altern...
