A wide variety of ina bushings options are available to you, bushes, maintenance-free, with bronze backing.

PTFE 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.

Steel and Steel/Bronze Plain Bearings

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.

We stand behind the quality of our Cylindrical Bushes in Metal-Polymer Composite Material Bronze Back + Porous Bronze Sinter +PTFE + Lead products .

DU 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 DU 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 PTFE plate.

Characteristics

• Very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions

• Suitable for lubricated applications

• Suitable for linear, oscillating and rotating movements

• Bronze back offers improved corrosion resistance in humid/saline environments

• Approved to standard EN 1337-2 for structural bearings for civil engineering

Material Structure

DUB PTFE Coated Bronze Bushing DIN1494(ISO 3547) the size is like DU-B Bushing, PAP bushing MU-B series.

1. PTFE/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 PTFE layer and transfer the heat more quickly.

3. Bronze plate, bear high load and transfer heat, anti-corrosion.

Typical Applications

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.
