We have advanced processing equipment to ensure the bronze bushings production and processing quality.

Self-lubricating bronze sleeve bushings for excavator

Excavators are the main equipment for mining open pit mines. There are many parts that use copper bearings on excavators. Self-lubricating bronze bushing with high-force brass matrix (Graphite Impregnated Brass Sleeve Bearing) will be used on the big arm of excavators, and wear-resistant aluminum bronze copper bushing will be used on the pushing and pressing mechanism of excavators, and copper bushing will also be used on the walking part of excavators.

The graphite copper sleeve on the upper arm is a kind of high performance solid lubrication product inlaid with graphite or MoS2 solid lubricant on the matrix of high-force brass.It breaks through the limitation that the general bearing depends on oil film lubrication.In the process of use, the friction heat causes friction between solid lubricant and shaft to form an excellent condition for the coexistence of oil and powder, which not only protects shaft from wear, but also makes the solid lubrication characteristics eternal.Its hardness is twice as high as that of ordinary copper sheath, and its wear resistance is also twice as high.

Self-lubricating excavator bushings material

The main material is aluminum bronze sleeve bushing.

The aluminum content of aluminum bronze bushing sleeve is generally not more than 11.5%, and sometimes appropriate iron, nickel, manganese and other elements are added to further improve the performance. Aluminum-bronze sleeve bushing can be strengthened by heat treatment. Its strength is higher than that of tin bronze sleeve bushings. Its resistance to high temperature oxidation is better.

Why do we use aluminum bronze sleeve bushing advantages?

Aluminum bronze has good cutting and grinding performance, can be welded, easy to form hot machining.The alloy is mainly used for manufacturing support, gear, shaft sleeve, bushing, nozzle, flange, rocker arm, guide valve, pump rod, CAM, fixed nut and other high strength and wear resistant structural parts.With high strength and wear resistance, widely used in high-voltage electrical appliances, shipping industry, after quenching and tempering treatment can further improve the strength, wear resistance and antioxidant.

As a professional self-lubricating bronze bushings manufacturer, our factory production of copper bearing role is very extensive, copper, used for sliding bearing, bearing than the normal amount of savings, can bear more load, copper sleeve, also known as copper bearing, need to lubricate the bearing oil.It is made of various copper alloys for lubrication of mechanical parts.With a variety of large, heavy machinery, machinery is an important component.
