The Metal-Polymer Bronze Backed Plain Bearing is a specialized type of bearing designed for applications requiring high load capacity, durability, and low friction. It combines the strength and rigidity of a metal backing, typically bronze, with the non-stick, low-friction properties of Polytetrafluoroethylene () or ptfe.
The bronze backing provides the bearing with excellent load-bearing capacity and dimensional stability, while the lining ensures smooth, wear-resistant operation. The combination of these two materials allows the bearing to handle both radial and axial loads effectively, with minimal friction and wear.
This type of bearing is often used in applications such as machine tools, automotive components, aerospace equipment, and other precision machinery where smooth, reliable operation is critical. The bronze backing also allows for easy installation and removal, as it can be pressed or screwed into place using standard bearing installation methods.
In summary, the Metal-Polymer Bronze Backed Plain Bearing offers a robust and reliable bearing solution for applications requiring high load capacity, low friction, and smooth operation.
A wide variety of ina bushings options are available to you, bushes, maintenance-free, with bronze backing.
bushing bearing, self lubricating bushing Material Features It is a new type bushing without lead composition which is developed aiming at increasing demands on environmental protection.welcome to ask a quote.
Plain bearing and rod end designs that require maintenance with steel/steel and steel/bronze material pairs are easy to maintain, cost effective, and excellently suited to alternating loads. Plain bushes, washers, and strips employ the low-maintenance metal-polymer composite E50. The sliding layer features lubricant pockets, which means that an initial lubrication is sufficient in most cases.
Bushing is of high safety factor,it is particularly suit for the working condition of high temperature and where no oil can be added or wherethe machine must work successively for long time.The bushing is widely used in steel metallurgy industry including sliding ways of successive casting machines,cement grouting pumps and spiraling conveyers for cement.It can also be pressed into a steel housing and work as an assembly;it can also be made as flange type which can move both in radial and axial directions.
Wear plate made from bushing material can be used in sliding part of bridge underprop.It can stand pressure of 130N/mm2 if we use a thicker wear layer and can be substitute of pure plate.
DUB Coated Bronze Bushing DIN1494(ISO 3547) the size is like Bushing, PAP bushing MU-B series.
1. /Pb composition, anti-abrasion material, which will form a lubricating film during operation.
2. Bronze powder layer, which further strengthen the combination of the bronze plate and layer and transfer the heat more quickly.
3. Bronze plate, bear high load and transfer heat, anti-corrosion.

Bearing forms made to order: standard forms in special dimensions, thrust washers, flanged thrust washers, half-bearings, special shapes obtained by stamping or deep drawing, customized bearing designs
Bushings offer very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions
Bushing material suitable for lubricated applications
Anti-friction bearing suitable for linear, oscillating and rotating movements.
This bearing bushing material meets the demanding criteria for long life and trouble-free performance with or without lubricant, of high safety factor even.
The bronze backing provides a high corrosion resistance, anti magnetic properties and a good thermal conductivity, The bearings are particularly appropriate for high temperature environment where no oil is efficient and the machine must be under successive long period working condition. The typical applications covered steel metallurgy industry such as bushes for roller grooves of successive casting machines, cement grouting pumps and screw conveyers for cement and so on.
