David from CanadaOur company import the bronze gleitlager from viiplus china,viiplus professional team makes sure customs clearance is always smooth. They provide an accurate bronze bushing classification, handle all the paperwork,We have received the self-lubricating bronze bushings. They look well done and the high quality.
Valerie from CaliforniaWe import the bronze gleitlager from China to under the incoterm FOB shanghai, sometimes by Air. viiplus is a very good bronze gleitlager supplier, they are very professional and patient, after we inform the new order, they will manufacturer bronze gleitlager in time and give us the schedule , and then we just need to receive the bronze parts
Daisy From GermanyThe best surface finishes for Sleeve Bearing, tighter concentricity, and bronze bushings material uniformity. The good supplier of standard inch and metric sleeve bearings and bushings from china.

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 .
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
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.

Bearing forms available in standard dimensions
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
DU-B 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.
