Description:

STEEL PLATE SELF-LUBRICATING BUSHING

It's made of high quality low-carbon steel plate, sintered porous bronze as its interlayer and the

compound of PTFE material and Pb as its surface. It can offer the properties of good self-lubricating anti-

abrasion, low-friction and fully develop the advantages of metal and multi-element polymer. It's used in

steel metallurgical industry, such as those used in roller grooves of successive casting machines, cement

grout pump and spiral conveyers for cement etc.

Sleeve Bushing with PTFE

Application Feature:

1). Working under oilless 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.

4).Thin-walled structure, light in weight, which can reduce the machine to small size.

5). Forming a transferred film during operation to protect, safe and trouble free.

6). Low demand to the shape even no surface hardness treatment, which lower the cost of the mating

components.

7).No absorption to water/oil, small coefficient of thermal emption, good thermal conductivity and size

stability

8).The back of the steel strip can be plated with various metals, anti-corrosion

Maintenance

It is a bushing with PTFE sliding layer. Lubrication is therefore not necessary, but basically possible.

Applications:

1, DYB101 (DU-SF-1), widely used in hydraulic vehicle, tobacco machines, forests machines and so on

2, DYB 201(DX-SF-2), Widely used in vehicle chassis, forming machine tools, rolling steel industry and so

on.

3, DYB 104(Lead Free), widely used in food machine, pharmaceutical machine

4, DYB 106, widely used in auto mobile, motor damper and oil pumps

5, DYB 500, widely used in consecutive casting and rolling machines, mine-exploiting equipments, ships,

steam engine
