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.
