  • Patent number: 11273988
    Abstract: A bearing housing with improved protective element and non-separable conveyor pulley that reduces metal use, labor, assembly and maintenance costs. The conveyor pulley includes a tubular housing, an axle, two bearing housings with an integrated bearing protection and two bearings. 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. The proposed configuration provides protection for pulley bearings from dust and abrasive particles. The bearing housing assembly is manufactured using polymer composite materials by injection molding with embedded parts. The bearing housing includes a slanted bevel proximate outer side of the housing facet to facilitate installation into the pulley housing. The conveyor pulley housing tube is form-pressed around the slanted face to form non-separable conveyor pulley.

  • Patent number: 10954071
    Abstract: 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.

  • Patent number: 10858195
    Abstract: 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.
