Product Description

Bronze bushing with good abrasion and corrosion resist bimetal sliding bushing





Features of Bushing


No lubrication required (PTFE composite)

Minimum wall thickness, minimum space requirements

Accommodation of heavy loads

Wide range of temperatures

Good sliding properties

High wear resistance




Oilless bearing (bushing) takes steel plate as a substrate and is a kind of wrapped sliding bearing by


agglutinating spherical bronze powder inside the middle part and rolling the mixture of PTFE (PTEE) and


lead on the surface. It has the characteristics of small friction coefficient, wear-resisting, corrosion


resistance and oil-free lubrication. Using this product can reduce costs, reduce mechanical volume, avoid


bearing seizure phenomenon and reduce mechanical noise. The product has been widely applied in the


sliding parts of various machinery, such as printing machine, elevator, spinner, tobacco machine, body-


building, instrument, hydraulic pressure van, micro electrical machinery, solenoid valve, automobile,


motorcycle and farm & forestry machinery and so on.


1, Non-oil lubrication or less lubrication


2, Low maintenance, with better abrasion resistance


3, Low friction index and anti-aging.


Roughly introduction:




1. PTFE with mixture 0.01~0.03mm


2. Porous bronze 0.2~0.3mm


3. Steel backing 0.7~2.3mm


4. Tin-plating 0.005mm or copper plating 0.008mm

SF-4 Advantages


1. Saving copper material, saving labor hours of turning


2. Low weight and low cost


3. Re-oiling period is prolonged usually to 5 times


4. High load capacity and particularly fitted for relatively rough wear, mating surface


5. Ready for change, available from stock
