Copper CuSn7Zn4Pb7 Multiple Loop & Circular Self Lubricating Grooves Bushing for Mining Loading.

Lead-tin bronze sleeve bushing manufacturer, For filled grooves type bearing surfaces, the groove pattern is machine precisely into the part.

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.
