The invention relates to a roller arrangement (7) for a stowing roller conveyor, comprising a stationary roller axle (20) arranged in a support frame (4) of the stowing roller conveyor, with a driving roller (9) and a conveying roller (10) adapted to be driven and/or braked, if necessary, being rotationally supported on said roller axle; as well as a clutch system (12) arranged between said driving and conveying rollers and comprising clutch components (14, 15) adjustable in relation to one anot...

A roller conveyor using a motorized drive roller has the drive roller located other than in the terminal roller position of conveyor zones. Damage to the motorized drive roller from overheating or impact loads is minimized.

A pinch roller which includes a cylindrical elastic body formed of a polymer blend including acrylonitrile butadiene copolymer rubber (NBR), and at least one of a highly saturated copolymer rubber containing nitrile group obtained by hydrogenating a butadiene part of said acrylonitrile-butadiene copolymer rubber, and ethylene-.alpha.-olefin type copolymer rubber, and a resin sleeve press-fitted in the elastic body. The elongation of the elastic body is set to be at least 5% and not more than 15%...

An adhesive roller for detritus removal having an elongated strip where the strip has both a backing layer and an adhesive layer overlying and covering a first side of the backing layer. The strip also has a first end, a second end and two spaced apart sides. The strip is wound from its first end and to its second end into a tubular cylindrical roller with the adhesive layer facing outwardly. An adhesive release coating also overlies at least a portion of a second side of the backing layer. The ...

Roller shoes in which a roller is installed on a shoe base in a detachable manner comprises a plurality of roller installation grooves formed at the center of the shoe base, a roller axle support inserted into the roller installation grooves, wherein the roller is attached to the roller axle support by a magnetic force, a break mechanism formed at both ends of a middle portion of the front and utmost end of the rear of the shoe base, and a cover mounted in the roller installation grooves. A roll...

An improved surface for an outer race member of a roller bearing by providing an annular curved surface between the circumferential crown surface and the annular corner radius surface. This improved surface has one end thereof tangent to the crown surface and the other end thereof tangent to the corner radius surface. The center of the radii of the curve increments therebetween being on a line connecting the centers of the crown radius and the corner radius and the radii uniformly diminish from ...

A device for converting a constant rotational input into a rotational output which is proportional to a separate input signal characterized by first and second members each having a surface of revolution about an axis with the surface of at least one of the members having an axially changing diameter and the first and second members being mounted for rotation with their surfaces adjacent one another, means for rotating the first member, a transfer device including a pair of rollers mounted for r...

A roller skate of the shoe-attached two wheel type includes for each skate a pair of U-shaped wheel support members appropriately spaced for the size shoes it is to be used with by a pair of side support members and attachable to a heel plate and a toe plate respectively which are attached to the shoe.

A roller bearing (10) includes a plurality of bearing rollers (12) located between confronting bearing surfaces (16, 19), the bearing surfaces being rotatable one relative to the other about the rotational axis of the bearing, and the bearing including biasing elements (18) which provides a force acting in a direction between the confronting bearing surfaces (16, 19) whereby, under all load conditions for which the bearing is designed for use, each bearing roller is retained in contact with each...

A roller assembly including fixing means for securing the roller assembly to a bottom rail of a window sash or a door. The roller assembly has a hollow outer frame in which is provided a pair of vertical legs each having a ledge disposed in a slot formed through a side wall of the outer frame. A screw having a countersunk head in the outer frame upon clockwise rotation urges the ledges to be pressed against side panels of the bottom rail, thereby holding the roller assembly in place within the b...
