A roller for a conveyor system comprises a nonlinear bore hole to facilitate retention of the roller on a roller-receiving portion of a corresponding shaft. A nonlinear bore hole comprises a central cylindrical portion for receiving a roller-receiving portion of the shaft and unaligned slots in communication with the central cylindrical portion to prevent migration of the roller from the roller-receiving portion.

A belt conveyor includes rollers spaced apart in a conveying direction along a carryway run on which a conveyor belt is moved. Each of the rollers includes a cylindrical body including an outer circumferential peripheral surface, in contact with the conveyor belt, and a thickness extending between opposed ends, and a wear indicator between opposed ends for providing a visual indication of wear in the cylindrical body in one embodiment and an audible indication of wear in the cylindrical body in another embodiment.

A transport roller brush assembly that includes a base that is constructed to support a plurality of brush wires such that the plurality of brush wires are oriented to extend in a radial direction relative to an axis of rotation of an underlying material transport roller. The base is preferably split into at least two arcuate portions that can be removeably secured to one another preferably via cooperation of a plurality of collar or collar portions and such that the respective and preferably two arcuate portions generally circumscribe a transport roller when the base is secured thereto. Discrete brush assemblies are preferably provided in a plurality of inner and outer radial dimensions such that roller brush assemblies as disclosed herein can be used with transport rollers of various outer radial dimensions.

A tire may comprise a hub and a plurality of discrete traction elements coupled to the hub. Each of the traction elements may comprise a backing plate and an elastomeric material bonded to the backing plate. Circumferentially adjacent traction elements may axially overlap.

An O-ring and a conveyance apparatus are provided. The O-ring includes an O-ring body having an annular shape. The O-ring further includes a plurality of protrusions arranged at intervals on an outer annular surface of the O-ring body and configured to support a glass substrate and convey the glass substrate as the O-ring body rotates, so that a total area of contact between the glass substrate and the O-ring is reduced, thereby reducing a print area. In addition, after the protrusions and the glass substrate come into contact, contact marks are in a discontinuous state or, in other words, are in a spaced state, and prints are also discontinuous or spaced prints, thereby mitigating visual effects of the prints, and eliminating the prints at low costs.

A conveying unit for transporting goods on transport rollers in a transport plane. The transport rollers can be rotated about their respective axes of rotation with an adjustable rotational speed and adjustable direction of rotation. The axes of rotation of the transport rollers are adjustable by rotation about their respective pivot axes by a particular pivot axis angle, and at least two of the transport rollers can be adjusted differently from one another. There is also described a method for adjusting the conveyor unit.

A conveyor roller for conveying systems for conveying articles comprises a cylindrical roller body having a rotation axis, the cylindrical roller body being provided for the rotatable assembly in a frame or the like, wherein one or a plurality of substantially frustoconical sleeves is/are disposed on the cylindrical roller body. The cylindrical conveyor roller includes a positioning installation by which the frustoconical sleeve is axially fixed at least along the rotation axis in at least one direction, wherein the positioning installation comprises a protrusion which axially extends in a radially outward manner on the cylindrical roller body and which extends into a clearance that is configured in the frustoconical sleeve. A production method for such a conveyor roller is also disclosed.
