Bearing and bearing protector with improved performance characteristics, reduced material use, lower cost of manufacturing and maintenance. Bearing protector includes air permeable element (e.g., wool, felt) that is configured to allow passage of air while preventing dust and other particulars from entering the bearing thereby improving bearing operation and longevity. Felt may be impregnated with a lubrication fluid to provide additional lubrication and protection. A self-lubricating bearing (SLB) is manufactured from an engineering plastic and is fitted with integrated bearing protector. The self-lubricating bearing includes one or more linear groves. When fitted onto an axle, the groves may receive excess plastic material that may occur during thermal expansion of the bearing during operation due to friction and heating. Plastic material may include an antifiction agent and the groves may be packed with consistent lubricant in order to reduce friction and improve performance.

A toner transporting device includes a bearing, an opposing section, a flange, and an engaging section. The bearing has an inner ring supporting a shaft, rolling elements disposed on an outer periphery of the inner ring, and an outer ring disposed around the rolling elements to surround the inner ring. The opposing section is disposed facing a first side of the inner and outer rings. The flange is provided at a second edge at a second side of the outer ring, extends in a direction of the shaft, and covers at least a part of a second end surface at the second side of the inner ring. The engaging section serves as a first edge at the first side of the outer ring, extends out relative to a first end surface at the first side of the inner ring, and engages with the opposing section in a relatively movable manner.

The present disclosure provides a roller and a locking method thereof. The roller includes a main body, a first groove provided on an inner surface of the main body, and a first elastic component fitted with the first groove; wherein a through hole for receiving and fixing a shaft is provided on the first elastic component. The present disclosure can be used to lock shafts.

Seal assemblies for conveyor idler rolls are provided. In some embodiments, a plurality of subsets of seal components are selectively installable in the seal assembly. In some embodiments, one or more fins are included on a seal.

A pinned roller bearing assembly and cage wherein the pin has two ends, a first end received in a first support ring, and a second end received in a second support ring, the pin comprising a threaded portion at one of the first or second ends, and the other end which is not threaded, or at least one shouldered end for engaging a countersunk support ring, or both a threaded end and one or both ends being shouldered.

A conveyor system includes a conveyor assembly. The conveyor assembly includes a conveyor module, a power module, and a chassis supporting the conveyor module and the power module. The conveyor module includes a roller rotatable about an axis and a conveyor belt shiftable in response to rotation of the roller. The power module provides rotational power to the roller. The power module includes a power assembly and a drive configured to transmit rotational power to the roller from the power assembly. The power assembly includes a power source and a housing at least substantially surrounding the power source. The chassis integrally forms a portion of the housing.

Conveyer pulley with improved performance characteristics reduced metal use, lower labor use manufacture, assembly and maintenance. The pulley includes a tubular housing, an axle pre-fitted with disks supports, two plastic endcaps press-fitted into the housing. Two self-lubricating plastic bearings with integrated bearing protectors are fitted onto the axle and into the end caps and are being kept in place by two retaining rings. Protector element of the bearing is fabricated from felt that is impregnated with a lubrication fluid. Inner grooves of the bearings may be packed with consistent lubricant.
