Bushings Material Steel bronze sinter & POM with lubrication indents | Orange POM Slit Greasing Hole Bushings
Metal-polymer marginal lubricating bearings
Metal-polymer marginal lubricating composite materials consist of metal backing sintered porous bronze with POM or PEEK
polymer as working layer. Steel backing provides exceptionally high load carrying capacity, excellent heat dissipation. Sintered
bronze powder provides thermal conductivity away from the bearing surface, also serves as a reservoir for the resin mixture.
And the POM or PEEK polymer layer provides high wear resistance and low friction even with only minute volume of lubricant
are supplied, this bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the
According to the different working conditions and environmental protection, the POM or PEEK layer with different polymer
filler, Surface tin or copper plating.
Our bushings product range includes POM Bushing colour yellow,POM Bushings colour orange,POM Bushings colour blue,POM Bushings colour black,PEEK.
Steel + Bronze Powder + POM (orange)
Recommended for applications involving intermittent operation or boundary lubrication...
Automotive: Pedal assembly, Balance shaft sleeve, Steering king pin shaft sleeve...
Logistics machine: carrier, chain block, Car crane, packaging machine....And hydraulic motor,Hydraulic cylinders, pneumatic
element, agricultural machine...
It has been
widely applied to winding engines, printing and dyeing machinery, coalcutters,
punch, winch truck, traveling crane etc.
It is similar with DS bushing in foreign countries,it can work even if it is without lubricant or under atrace of oil.It is of low fritction,anti-corrosion and is of long life. It can be used in machines under oscillating motion and in open field or in corrosive environment such as windlass,buldozer, tower eranes and printing or dyeing machines for textiles industry.
VSB-20 Boundary lubrication bearing High Quality DX Bushing POM Bush China Manufacturer
· marginally lubricated bushings for grease or oil lubricated applications
· Standard parts contain grease indents in the sliding layer; plain sliding layer available by request
· Optimum performance under relatively high loads and low speeds
· Suitable for linear, oscillating and rotating movements
· Wide range of parts available from stock
Suitable for rotating and oscillating movement, less maintenance requirements due to the long re-lubrication intervals, lower wear, lower susceptibility to edge loading, no absorption of water and therefore no swelling, good damping behaviours, good resistance to shock loads.
Marginal Pb-free self-lubricating bearing based on steel backing,
sintered porous bronze as its interlayer, surface rolled by acetal resin and
polymer material constaining oleophylicity fiber and perform well on low friction
factor, well wear performance and oil free condition lubrication.
STRUCTURE AND COMPOSITION
· Metal-Polymer Composite Bushing Material
· Steel Back + Porous Bronze Sinter +POM with Lubrication Indents
1. POM thickness 0.30~0.50 mm. It provides high wearresistance and low friction even with only minute volume oflubricant are supplied, this bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing.
2. Sintered bronze powder thickness 0.20-0.35mm. A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the PTFE layer and conducts the thermal build up away from the bearing surfaces.
3. Low-carbon steel.Setting the foundation of the bushings, the steel back provides exceptional stability,load carrying and heat dissipation characteristics.
