C90800 Bush CuSn12 Tin Bronze Graphite Plugged Bushing
Tin Bronze Graphite Plugged Bushings C90800 CuSn12 are high-performance bearing components that offer exceptional wear resistance and lubrication properties. These bushings are made from tin bronze alloy C90800, also known as CuSn12, which combines the strength and corrosion resistance of bronze with the lubricating benefits of graphite.
The graphite plugs within the bushings provide additional lubrication, reducing friction and enhancing the overall performance of the bearing. This design ensures smooth and reliable operation, even under high loads and speeds.
Tin Bronze Graphite Plugged Bushings C90800 CuSn12 are suitable for a wide range of industrial applications, including valves, pumps, and other machinery where high-performance bearings are required. Their durability and reliability make them a cost-effective solution for reducing maintenance and extending the service life of equipment.

Graphite Bronze Split Bush
- Copper Alloy Straight, Standard / Thin Wall, I.D. F7 O.D. m6
Our present position in the industry is chiefly attributable to our specifically designed Graphite Bronze Split Bush from our exclusive collection of products
The solid inlaid bearing is on a brass matrix.A high performance solid lubricant inlaid with graphite or MoS2 solid lubricant.It breaks through the limitation that the general Graphite Bronze Bearings depends on oil film lubrication.In the process of use, the friction heat makes solid lubrication and shaft friction, forming an excellent condition for oil and powder to coexist lubrication, which not only protects shaft from wear, but also makes 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.At present, the Graphite Bronze Bearings product has been used in metallurgy continuous casting machine, train support, steel rolling equipment, mining machinery, ships, gas turbines and other high temperature, high load, low speed heavy load and other occasions.

·Comparable with most viscous lubricants, oils, and grease
applications.
Graphite Bronze Bearing-Imperial line bushings (dimensions in inches)
Graphite Bronze Bearing are metal backed with bronze alloy graphite oil-less bushings.
These are multi-layer composite bearings made of a special sintered material used as sliding surfaces and a steel material as a support metal. The sintered layers are made of a special copper-nickel alloy containing a uniformly dispersed solid lubricant, the main component of which is graphite. Solid lubricants will be released to the surface of the ring as they wear, which will ensure a lower coefficient of friction during operation. In addition, these sintered layers were treated by the oil impregnation treatment.
1.no oil supply device, oil hole, oil groove
The cost of the fuel supply system, the cost of processing,
assembling, and so on, can greatly reduce the cost of
manufacturing.
2.Operation cost reduction
Greatly reduce the use of lubricating oil and equipment maintenance
costs, but also exempt from the risk caused by the shortage of oil.
3.design time shortened
No oil can make the design, structure is greatly simplified, reduce
costs, save design time. In addition, using self-lubricating
bearings can also improve the mechanical properties and prolong get
remarkable results using life and improve the reliability.
4.recovery and environmental protection of lubricant
No need to waste oil recycling, is conducive to environmental
protection.
1.In the possible case, the design uses the standard specification as far as possible;
2.Please note that there is no foreign body in the assembly;
3.After using the sliding surface, formed by solid lubricant oil
film in surface with black or gray black phenomenon, please do not
scrub, as usual.
4.Before the assembly, if the lubricating oil applied to the
grinding parts, can shorten the running in period, conducive to the
operation of machinery, operation;
5.When the assembly should be slowly pressed into, it is strictly
forbidden to beat, so as to avoid damage to the Graphite Bronze
Bearings and deformation;
6.Design, different parts should be selected with appropriate
material, in order to improve the mechanical performance, to extend
the service life of the Graphite Bronze Bearings;
7.In the high load, reciprocating motion, the proposed use of screw
fixation;
8.In fresh water, sea water and in the sea, on the use of stainless
steel or surface plating.
1. Flexible, simple, convenient design with wide applications
2. FunctionaI in absence of oiI
3. Cost efficiency
4. Excellent performance under high load and low speed
circumstances
5. In circumstances where it is difficult to generate hi-films,
such as reciprocating movements, rotating movements and frequent
on-off, Graphite Bronze Bearings highlights its excellent abrasion resistance.
6. Excellent chemical resistance and corrosion resistance
