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.
