Copper Bushing Manufacturer

Copper sleeves, also known as copper bushings, are divided into many types, including machine copper rollers, copper bearings, etc. It is used in various light industries, large and heavy machinery, and is an important component of machinery.

Traditional Tin Bronze Bearing

High hardness, excellent wear resistance, not easy to cause seizure, good casting performance, and cutting performance, and good corrosion resistance in the atmosphere and fresh water. In the absence of lubricants and water-based lubricants, it has good sliding properties and self-lubricating properties, easy cutting, and good corrosion resistance to dilute sulfuric acid. Used in Marine Engineering, Construction Bearing, etc.

Graphite copper bearing, the surface consists of a metal substrate and a molded solid lubricant with unique self-lubricating properties embedded in the holes or grooves of the substrate. The graphite-plugged copper bushing combines the respective advantages of metal and specially formulated lubricating material, which can complement each other, i.e., it has the high load-bearing capacity of metal and the lubricating performance of wear-reducing material, breaking through the limitation of general bushings relying on oil film lubrication.

Self-lubricating Graphite Plugged Copper Bearing

Copper bearing with graphite makes solid lubrication and shaft friction through friction heat in the process of use, forming excellent conditions of oil and powder coexistence lubrication, which not only protects the shaft from wear but also makes the solid lubrication characteristics eternal. However, its hardness is twice as high as general bushings, and its wear resistance is also twice as high.

A Large Copper Sleeve Bushing

Centrifugal casting is widely used in producing copper sleeves. As pore and inclusion defects appearing in the sur- face were eliminated, obtaining excellent huge marine copper bushing bearing.

Large copper bushings are used on various large and heavy machinery and are important group city parts on machinery.

Types Of Copper Bearing

Our copper bearing products include graphite copper bushing, white graphite copper bearing, flanged copper sleeve bushing, automotive mold guide bushing, double flange shaft tile, mold guide bushing, square flange copper bushing, self-lubricating guide plate, thrust washer, joint bearing, graphite steel bushing, and non-standard customized copper bushing.

The Rocker arm of the shearer, traction between the bracket and hinged with cone shaft taper sleeve, downhole in use process, often appear the rocker and bracket, bracket and traction of hinged lock cone axis, radial normal lift and remove the difficult problem. Aiming at the problems， from two aspects of design and use of analysis research, through actual use of graphite embedded copper bearing, to improve the lubrication effect of the cone shaft, improves the wear resistance, effectively solved the problem of the cone shaft lock.

Improve Efficiency & Save Cost

Long-term use of self-lubricating graphite bushings without frequent maintenance, reducing the amount of worker labor and improving coal mine production efficiency.
