PVD equipment vacuum annealing furnace
The bearing pad is equivalent to the outer ring of the sliding bearing, the bushing is integral and the opposite axis is moving, while the bearing bush is segmented and the opposite axis is rotating.

a journal: a portion that constitutes a shaft that is supported by a bearing;
Bearing bush: a part that matches the journal;
Bushing: A sleeve made of a full cylinder.
In the LEGO Mindstorms series and BioTrans RoSys series of robot components, the sleeves are specifically referred to as the silver-gray LEGO standard shaft holders, which are divided into full sleeves and 1/2 sleeves.
Bushing material
Specifications of plastic bushings: POM polyacetal plastic bushings, PA nylon plastic bushings, PTFE PTFE plastic bushings, Teflon plastic bushings, Teflon plastic bushings. Characteristics of plastic bushings: acid, alkali, corrosion, mechanical strength, good wear resistance, heat resistance, oil resistance and chemical resistance.The plastic bushings are made of PTFE/Teflon/Teflon/Teflon, POM, POM, PP, and PP. Products used in aerospace, automotive, sensors, medical, pharmaceutical, satellite, valves, pumps, sanitary, electronics, bearings, electrical, and other industries.
Bimetal bushing parts are patented products and are a new material for profiled and standardized bushing products. Mainly for the various shaft processing enterprises and general machinery factories and mechanical repair companies, providing a near-neck material (Near Net Shape Material). With this bi-metal bushing part-shaped material, a very small amount of machining (such as chamfering, drilling, car or oil sump) can be used as a sleeve product for direct installation.
What is the role of copper bushings in machinery?
1. Fixed
When the gear shaft is moving, try not to let it shift direction due to vibration. At this time, you need to use a copper bushing to help it fix. The most important role of the copper bushing in the machine is the fixed position, which is all the performance of the copper bushing.

2. Plain bearing
This is another role played by the copper bushing in the machine. In order to reduce expenses and cost, it is necessary to use sliding bearings at this time, and the copper bushings just have this function. It mainly designs the thickness of the sleeve according to the axial direction of the bearing. In fact, the copper sleeve is a kind of sliding bearing, which can be used when the mechanical rotation is relatively low and the clearance requirement is relatively high. A copper bushing replaces the rolling bearing for operation. The copper bushings are wear resistant and can be used for a long time, so in a large part this can help to save costs.
What are the main applications of copper bushings?
The copper sleeve on the shaft acts as a bearing. It belongs to the general category of sliding bearings. It is a bearing that works under sliding friction. The opposite shaft is rotating, and it is generally necessary to assist the lubrication system. The sliding bearing works smoothly, reliably and without noise. Under liquid lubrication conditions, the sliding surface is separated by the lubricating oil without direct contact, and the friction loss and surface wear can be greatly reduced, and the oil film also has a certain vibration absorbing capability.

The functions are lubrication, heat dissipation, friction reduction, and extended life.
Copper sleeves are mainly used in machinery, printing and dyeing, paper, chemical, aerospace, coal, petroleum, automotive, engineering machinery, metallurgy and other industries.
