What is a bushing? RICITE Richter Xiaoan introduces it to everyone. The bearing shell is equivalent to the outer ring of a sliding bearing; the bushing is integral and moves relative to the shaft. In contrast, some bearing shells are segmented and 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 shaped as a complete cylinder. In the LEGO Mindstorms series and BioTrans RoSys series of robot components, the term “bushing” refers specifically to the silver-gray LEGO standard axle holders. There are two types: full bushings and 1/2 bushings. 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 used 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 care, pharmaceuticals, satellites, valves, pumps, plumbing, electronics, bearings, and electrical appliances. The material for bimetallic bushing components is a patented product; it represents 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 mechanical 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 the gear shaft is in motion, efforts should be made to prevent it from deviating in direction due to vibrations. In such cases, a copper bushing is needed to help secure it in place. The most important function of copper bushings in machinery is to maintain a fixed position; this encompasses all of their properties. 2. Sleeve bearings This is another function that copper bushings serve in machinery. To reduce expenses and cut costs, sliding bearings are needed at this point; copper bushings happen to possess this functionality. It mainly determines the thickness of the shaft sleeve for sliding bearings based on the axis direction of the bearing; in fact, a copper shaft sleeve is a type of sliding bearing. In situations where the mechanical rotation is low and relatively high 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 areas are copper bushings mainly used? The copper sleeve on the shaft functions as a bearing; it falls under the category of sliding bearings. It operates under conditions of sliding friction and rotates relative to the shaft. Generally, it requires a lubrication system to function properly. Sliding bearings operate smoothly, reliably, and silently. 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, automobiles, construction machinery, and metallurgy.
