RG7 CuSn7Zn4Pb7 bronze bearings are specifically designed for use in valves and other applications requiring high-performance and durability. The circular grooves type bushing is a common configuration for these bearings, providing optimal lubrication and wear resistance.
The CuSn7Zn4Pb7 alloy composition of these bearings offers excellent mechanical properties, including good strength, ductility, and wear resistance. The addition of lead (Pb) improves the material's self-lubricating properties, reducing friction and wear during operation.
The circular grooves in the bushing design allow for the effective distribution of lubricants, such as oil or grease. This ensures that the bearing surface remains well-lubricated, minimizing friction and wear. The grooves also help to trap any debris or contaminants, preventing them from damaging the bearing surface.
The RG7 CuSn7Zn4Pb7 bronze bearings are precision-manufactured to ensure dimensional accuracy and consistent performance. They are suitable for a wide range of valve applications, including those requiring high-pressure and high-temperature environments.
Overall, the RG7 CuSn7Zn4Pb7 bronze bearings with circular grooves type bushing offer superior performance, durability, and reliability for valves and other demanding applications.
Cast bronze sleeve bearings, flange bearings, and custom parts are available with oil grooves or grease grooves.

VIIPLUS SLIDING BEARING has developed various technologically advanced product lines to meet customers’ needs. Bronze Sleeve Bearings were designed to withstand industries with severe and harsh applications. The combination of the cast bronze alloy base and the solid lubricant results in a bronze bearing that is maintenance-free. This self-lubricating bearing has gained in popularity over the years with the increasing need to meet industrial requirements for energy and labor cost reductions.
Cusn7zn4pb7-c is considered the "standard" type of bearing material for lead-tin bronze. The alloy has excellent machining properties, good hardness, strength and wear resistance, excellent wear resistance. Typical applications include bearings, gaskets, bushing, auto parts, main shaft bearing, machine tool bearings, crane bearing, trunnion bearing, roller bearing neck, rolling mill bearings, the sleeve is the fuel pump and pump shaft sleeve, diesel engine piston pin bushing, forging toggle lever bearing, stuffing box hydraulic press, hydraulic press mainlining, pump impeller, gm liner, fitting, pump assembly, outer spherical bearings, and so on.

In most cases, Enduralube Bearings are used with a press fit in the same manner as general sleeve Bearings. Fit the Bearings into housings using mandrels or press. In case of a relatively large interference, provide both the ID of the housing and the OD of the Bearing with chamfers, and fit the bearing into the housing with mandrel for easy installation.
Graphite Bearing products simplify your lubrication requirements by taking the difficult and seemingly impossible and providing a reliable, efficient, and economical solution. The simplicity of the Metal Sliding Bearing opens the way for product improvements and economies impossible with other types of lubrication. These benefits can make your products more competitive, simpler, and more desirable to the end-user.
Benefits of National’s Graphite Bronze Bearings:
• Continuous lubrication over long periods without maintenance
• Simplification of product design by eliminating need for lubrication lines, hoses, pumps, etc…
• Long term resistance to scoring and wearing of moving parts.
• Ideal for environments that can be contaminated by leaking lubricants.
• Extended product life by assuring lubrication every time bearing surfaces move.
• Able to withstand high-temperature environments where traditional lubricated bearings normally fail.
