Three Layers Metal-backed Composite Sliding Bearings

 

Three-layer metal-polymer composite plain bearings are self-lubricating and maintenance-free, and are particularly suitable for:

 

• Maintenance-free operation
• There is a risk of running out of lubricant
• Lubricants cannot be used or are prohibited
• Space is limited.

 

PTFE composite plain bearings have good dry sliding characteristics and do not require lubrication
POM composite plain bearings require an initial application of grease during mounting. Re-lubrication is not required but the presence or constant supply of a lubricating fluid or grease can extend bearing service life considerably。

 

 

Steel + bronze powder + PEEK/ PTFE

 

 

Three-layer metal-polymer composite self-lubricating plain bearings

 

·Self-lubricating layers, a mixture of PEEK/PTFE and antifriction materials such as fibers, significantly reduce the coefficient of friction and protect the grinding part.

·Bronze powder layer, as an attachment to the self-lubricating layer.

·Low carbon steel layer, play a good bearing and heat dissipation role

 

It is made of carbon steel substrate, bronze powder, PEEK/PTFE and fiber and other materials through special technology, which has the characteristics of environmental protection. It can be applied to the sliding and rotating, swinging and linear reciprocating motion parts of various machinery, and is suitable for difficult maintenance that cannot be refueled or difficult to refuel, no oil lubrication and less oil lubrication

 

 

Steel + bronze powder + POM

Boundary lubricated bearings

 

 

·Anti-wear layer, surface rolled modified POM, can significantly reduce the coefficient of friction and protect the anti-grinding part.

·Bronze powder layer, as an attachment to the self-lubricating layer.

·Low carbon steel layer, which plays a good bearing and heat dissipation role.

·Copper/tin plating with good corrosion resistance

 

The surface is rolled modified Polyoxymethylene (POM) and contains an oil storage pit. It can be applied to rotating, rocking motion under various low-speed heavy loads, and is usually used in intermittent operation and boundary lubrication environments. It has the characteristics of low friction coefficient, good walking performance and wear resistance during work
 

 

Copper + bronze powder + PTFE
Bronze-based oilless bearings

 

 

·Self-lubricating layer, transfer film can be formed during operation to protect the grinding shaft.

·Bronze powder layer, improve the bonding strength of PTFE and copper plate layer, high thermal conductivity can quickly transfer the heat generated during operation.

·The copper substrate layer plays a good bearing and heat transfer role, and has better corrosion resistance.

 

Better corrosion resistance than SF-1. Widely used in weak acid and strong alkali occasions, port machinery, ship machinery, metallurgical steel industry, continuous casting machine billet raceway, high temperature furnace steel ring part, cement grout pump and screw conveyor.
