These CuZn25Al6Fe3Mn4 bronze graphite bushings, also known as bronze sleeve bearings, feature a size of 20x30x30, which indicates an inner diameter (ID) of 20 millimeters, an outer diameter (OD) of 30 millimeters, and a length of 30 millimeters. The CuZn25Al6Fe3Mn4 alloy offers excellent strength, ductility, and corrosion resistance, making it a reliable choice for various applications.
The graphite impregnation within the bushings provides superior wear resistance and self-lubricating properties. This means that these bushings can operate smoothly with reduced friction and wear, even under high loads and speeds.
These bronze graphite bushings are commonly used in automotive, construction, and heavy machinery applications where reliability and durability are critical. They are suitable for both radial and thrust loading applications and can be easily installed into bearing housings.
 

Graphite plugged bearings are made of solid bronze with pre-integrated solid graphite lubricant. Their load limit is considerably higher than standard sliding bearings, where lubrication is dependent upon there being a film of oil.

 
These bronze bushing are made of C86300/C86200 CuZn25Al6Fe3Mn4 manganese bronze alloy used with heavy loads, in anti-corrosion applications or if it is very difficult to obtain lubricant. These bearings perform twice as well due to their strength and wear-resistance.
 
Customized bronze sleeve and flaged bushings are generally used in casting machines, in the mining and shipbuilding industries, in turbo generators and hydraulic turbines and for injection-moulding machines for the plastics processing industry.

Performance

 
Graphite Plugged Cast Bronze Bushings can be utilized where heavy loads must be supported at low to medium speeds
 
The Plug Graphite Cast Bronze Bushing is able to withstand high temperatures up to 570 F
The self-lubricating feature allows bearings to be used where oiling is difficult, expensive to implement, and where grease/oil cannot be used. Excellent lubrication is achieved even under high loads at low speeds.
Self lubrication with specially embedded solid lubricants reduces friction. Coefficient of Friction: 0.04 to 0.2
