Self-lubricating bearing custom bushing type, A plain bearing, also known as a bushing, is a mechanical element used to reduce friction between rotating shafts and stationary support members.

A bushing is a cylindrical component designed to support a load on a shaft in a sliding motion between moving surfaces. A bushing is a single element component, although it may be composed of several different materials.

Also known as a sleeve bearing, a bushing slides over a rod or shaft to provide extremely low frictional motion, providing excellent vibration damping and working to minimize energy use, noise and wear.

The two main types of bushings include sleeves and flanged bushings. When designed with flanges, they can handle combined loads. Bushings can be designed with internal oiling grooves or inlaid with graphite solid lubricants to accommodate a variety of assembly conditions

Metal polymer bushings, bearing bushings are akin to thin tubes most commonly used for machinery with rotating or sliding shafts to improve efficiency and reduce vibration and noise.

　　The specifications of plastic bushings. POM polyformaldehyde plastic bushings, Metal polymer bushings, PTFE Or POM bearing bushings, Teflon steel backed copper bronze bushings, Teflon bronze backed bushings. The materials of plastic bushings are PTFE, Teflon, Fabric, PEEK, POM, Plain Bearing. The Different Types of Bushings · Journal bearings are commonly used to support the linear motion of engine crankshafts in large turbomachines.

　　Bimetallic bushings are generally steel-copper alloy products with low carbon steel plate as the base material and sintered CuPb10Sn10 or CuSn6Zn6Pb3 material on the surface. Its parts material, which is a patented product, is a profiled, standardized new material for bushing products. Mainly for a variety of bushing processing enterprises and general machinery plants and mechanical repair enterprises, providing bimetallic bushing parts near the end of the shape of the material. With this bimetallic bushing parts shaped material, only a very small amount of mechanical processing (such as: chamfering, drilling, turning or pressing oil groove) can become directly installed and used bushing products.

　　Bronze bushings are typically made of continuous bronze material to ensure a uniform structure. They are general purpose bushings that provide excellent load and wear protection while having the ability to withstand high heat (temperatures up to 450°F). Metal bushings can also be made from a variety of metals or alloys to enhance their capabilities, including steel or stainless steel, brass, aluminum and brass bushing bearings.

　　Bronze bushings are divided into various types, including machine copper rollers, copper bearings, etc. It is an important component of machinery. The product has the traditional tin bronze bearing function, with electrolytic copper as the raw material with a variety of trace metal elements, by high temperature sintering, through the air pressure centrifugal casting processing. High hardness, excellent wear resistance, not easy to produce bite phenomenon, good casting performance and cutting performance, good corrosion resistance in the atmosphere and fresh water. In the lack of lubricant and water lubricant conditions, sliding and self-lubricating properties, easy cutting, casting performance is poor, good corrosion resistance to dilute sulfuric acid.

According to the different finished product standards of copper bushings can be divided into: self-lubricating copper bushings, need to give oil lubrication, graphite copper bushings and several other. Copper bushings are also common raw materials: tin bronze, aluminum bronze, brass, phosphor bronze, etc. Casting methods are distinguished as: metal casting models, precision casting, centrifugal casting, sand casting. Copper bushing is reasonable, there may be some mechanical designers do not like the existence of copper bushings, but often in the course of a long time of actual use, its advantages slowly come out Oh!

Bronze bush, also known as bronze sleeve, is made of copper through the casting of an accessory, applied to machine operations, it allows the operation of machinery and machinery to reduce friction, reduce vibration, anti-corrosion, reduce noise, easy maintenance, thereby simplifying the structure of the manufacturing process. Shaft sleeve processing approved titanium hao machinery, at present, the copper sleeve in the machine parts are widely used, but we face a long time machine operation, copper sleeve will also have a certain wear and tear, it will also have a life, if its wear program reaches a certain word, and affect the normal operation of machinery, but also to be replaced in a timely manner, at the same time is because the cost of casting copper kit is relatively cheap, so currently in the machinery manufacturing industry is widely used.

There are many other roles of bronze bushings, for example, it is a multi-faceted energy, both shock absorption, corrosion resistance, but also with toxic media isolation, increasing the life of the bearing. Still, it is mainly used for sliding bearings, which can use the bearings to withstand greater loads, and together with the lubricating oil, it is the best partner for mechanical parts parts, especially for applications on large and heavy machines and instruments. In order to keep the gear shaft from shifting due to vibration when it is in motion, copper bushings are used to hold it in place.

Therefore, the important role of bronze bushings in machines is to fix and position them. Another role of copper bushings is the role of sliding bearings, in which the thickness of the bushings is designed according to the axial load of the bearings in order to achieve cost savings. In fact, copper bushings are also considered a kind of sliding bearing. In some occasions where the speed is relatively low and the clearance requirement is relatively high, it can be used to replace the rolling bearing. Copper bush is very wear-resistant, the use of the realization can be very long, so to a large extent to save costs.

　　1、The Function of bearing bushings

　　Plastic bushings with acid, alkali, corrosion, mechanical strength, good wear resistance, heat resistance, oil resistance, etc. characteristics. General plastic bushings are used in aerospace, automotive, sensors, medical, satellite, valves, pumps, sanitary ware, electronics, bearings, electrical appliances, and other industries.

　　2、The Function of bimetal bearing bushings

　　Bimetal bushings have high bearing capacity, impact resistance, high temperature resistance, self-lubricating ability and other characteristics, especially suitable for heavy load, low speed, reciprocating or oscillating and other difficult to lubricate and form oil film occasions, but also not afraid of water and other acid corrosion and erosion. The products have been widely used in metallurgical continuous casting machine, rolling rigid equipment, mining machinery, molds, lifting machinery, textile machinery, wind power generation, ships, steam turbines, hydraulic turbines, injection molding machines and equipment production lines. The wear resistance is double that of ordinary bushings.

　　3、The Function of copper bearing bronze bushings

　　(1) Fixed. When the gear shaft is in motion, try not to let it because of vibration and directional shift phenomenon, this time it is necessary to use bronze bushings to help it fixed. Bronze bushings in the machinery is a more important role is to fix the position, which is all the performance of copper bearing bushings.

　　(2) Plain bearing bush. This is another role played by bronze bearing bushings in the machinery. In order to reduce expenses and save costs, this time it is necessary to use the sliding bearing, and bronze bushings just have this function. It is mainly based on the axial direction of the bearing to the sliding bearing to design the thickness of the bearing bush sleeve, and the fact that the copper bush is a kind of sliding bearing, when the rotation of machinery is relatively low, clearance requirements are relatively high in the environment can use the copper bush to replace the rolling bearing to operate. Copper bushings have wear resistance, can be used for a long time, so to a large extent so that it can help save costs.

　　4、Other Function of Bearing bushings

　　(1) Bearing bushing sleeve is widely used in the light load for easy disassembly. There are many bearings in the assembly and disassembly will encounter difficulties, especially in the case of internal bearing assembly constraints, the application of bearing bushings can solve the assembly and disassembly problems.

　　(2) Bearing bushing sleeve can be adjusted tight and loose, so that the processing accuracy of many boxes to be relaxed, so that the box processing efficiency greatly improved;

　　(3) the installation of bearing bush also overcomes the radial runout of the bearing. So the bearing bush is widely used, but there are some shortcomings, the accuracy of the bearing bush directly affects the radial runout of the shaft.
