Carbon Steel self-lubricating bearings used high quality low-carbon steel plate as base, sintered porous bronze as its interlayer and the compound of PTFE and Lead as its surface. It offers the property of good self-lubrication, low wear, low friction, good sliding characteristics, low noise. It has been widely applied to various mechanical sliding positions, such as textile machinery, printing machinery, hydraulic pressure transit vehicle, tobacco machinery, gymnastic instrument and agricultural machinery etc.
1).Working under ollies or minim oil state, maintenance free or just need a litter maintenance
2).Resist Abrasion, low coefficient of friction long operation life.
3).Operation in -195°C~+280°C.
4).Good mending, low-noise, non-pollution.
5).Thin-walled structure, light in weight, which can reduce the machine to small size.
6).Forming a transferred film during operation to protect, safe and trouble free.
7).Low demands to the safe even no surface hardness treatment, which lower the cost of the mating components.
8).No absorption to water/oil, small coefficient of thermal emption, good thermal conductivity and size stability
9).The back of the steel strip can be plated with various metals, anti-corrosion
It is a dry sliding bearing with PTFE sliding layer. Lubrication is therefore not necessary, but basically possible.

SF-1W is a new type bushing without lead composition which is developed aiming at increasing demands on environmental protection. Besides its wide application on general machines, SF-1 is particularly suitable for food machine, Pharmaceutical machine, tobacco, machine etc.
SF-1P is developed according to reciprocating motion of shock absorber and high pressure in flank, it can offer low friction coefficient and good anti-abrasion, be used in semi-dry condition. The product is applied to shock absorber of automobiles, motorcycles and pneumatic.
