What is a bushing? The bearing shell functions as the outer ring of a sliding bearing; the shaft sleeve is a single unit that moves relative to the shaft, whereas the bearing shell can be made up of separate pieces that rotate relative to the shaft. Bearing journal: The part of the shaft that is supported by bearings ； Bearing bush: A component that fits with the shaft journal ； Shaft sleeve: A sleeve in the form of a complete cylinder. Materials for bushings: Specifications for plastic bushings include POM polyoxymethylene plastic bushings, PA nylon plastic bushings, PTFE polytetrafluoroethylene plastic bushings, Teflon plastic bushings, and fluoroplastic bushings. Properties of plastic bushings: resistance to acids, alkalis, and corrosion; mechanical strength; as well as good wear resistance, heat resistance, oil resistance, and chemical resistance. The materials for plastic bushings include PTFE/Teflon/Polytetrafluoroethylene, polyoxymethylene POM, nylon PA, and polypropylene PP. The products are used in industries such as aerospace, automotive, sensors, medical, pharmaceuticals, satellites, valves, pumps, plumbing, electronics, bearings, and electrical appliances. The material for bimetallic bushing components is a patented product, representing a new type of standardized bushing material in the form of profiles. It mainly provides near-net shape materials for bimetallic bushing components to various bushing manufacturing enterprises, general machinery factories, and machinery repair businesses. Using this bimetallic bushing material, only minimal machining (such as chamfering, drilling, turning, or pressing oil grooves) is required to turn it into a bushing ready for direct installation. What is the role of copper bushings in machinery? 1. When fixed to the gear shaft and in motion, it is important to prevent it from shifting in direction due to vibration; at such times, copper bushings are needed to help hold it in place. The most important function of copper bushings in machinery is to fix positions, and this represents all of their properties. 2. Sliding bearings: This is another function of copper bushings in machinery. In order to reduce expenses and cut costs, sliding bearings are needed at such times, and copper bushings happen to have this function. It mainly determines the thickness of the shaft sleeve for sliding bearings based on the axis orientation of the bearing; in fact, a copper shaft sleeve is a type of sliding bearing. In situations where the mechanical rotation is low and a relatively large clearance is required, a copper shaft sleeve can be used as a substitute for rolling bearings. Copper bushings are wear-resistant and can last for a long time, which helps to reduce costs to a large extent. In what main areas are copper bushings used? The copper sleeve on the shaft serves as a bearing; it belongs to the category of sliding bearings, which are bearings that operate under sliding friction. It rotates relative to the shaft, and generally requires a lubrication system to function properly. Sliding bearings operate smoothly, reliably, and noiselessly. Under liquid lubrication conditions, the sliding surfaces are separated by the lubricating oil and do not come into direct contact, which also helps to **reduce frictional losses and surface wear. The oil film possesses vibration-damping properties, and its functions include lubrication, heat dissipation, friction reduction, and extended service life. Copper sleeves are mainly used in industries such as machinery, printing and dyeing, papermaking, chemicals, aerospace, coal, petroleum, automotive, construction machinery, and metallurgy.
