Product Description

The DU composite bushing/rolling bushing is a sliding bearing made of a steel plate as a base, sintered spherical bronze powder in the middle, and a mixture of polytetrafluoroethylene (PTFE) and lead rolled on the surface. It has the characteristics of small friction coefficient, good wear resistance, good corrosion resistance and no oil lubrication. The use of this product can reduce costs, reduce mechanical volume, avoid biting the shaft and reduce mechanical noise.


It has been widely applied to various mechanical sliding postions, such as texitile machinery, printing machinery, hydraulic pressure transit vehicle, tobacco machinery, gymnastic instrument and agricultural machinery etc.

Product Advantage

1. Dry or only a trace amount of grease or ill will be required. Maintenance free.


2. Good wear and friction performance over a wide range of loads, speeds and temperature without oil also perform well with lubrication.


3. Load spreads over a wider area due to the elastic nature of the bearing materials, resulting in a higher loading capacity.


4. The small differences between static and dynamic coefficient of friction enhance the accuracy of machines operating at low speeds.


5. Low vibration, low noise and reduced-pollution during operation.


6. and lead can form transfer films onto the mating surface to improve performance and prevent bushing binding.


Product Application

With the advantages of light weight, low noise and self-lubricating features, Steel bushings are widely used in the automotive industrial and the applications are still under fast developing. Currently, there are over 50 bushings being used in each of the passenger cars and more and more traditional needle bearing, sintered bearings are been replacing by the self-lubricating bushings.​

In addition to the bushing, the self-lubricating materials are applied to the other non-bearing parts such as the new resin coated air conditioner swash plate and other structure parts had already developed. Steel self-lubricating materials provide not only functional parts to the automotive industry but also provide a solution to this industry for environment protection with the materials conform with RoHS and REACH regulations.

Besides DU bearing is widely used in Lifting equipment, Hydraulics and valves, pneumatic equipment, medical equipment, textile machinery, agricultural equipment, construction equipment, meterial handing equipment, packaging equipment, automotive field, scientific equipment, drying ovens, office equipment, etc.


Competitive Advantage
