ADVANTAGES:
Can be used where no oil can be applied or oil is difficult to be applied.
Low wear, low friction and with long life. Load will spread over a wider area due to the bearing material’s elastic nature.
Low stick slip properties ensuring accuracy of machine operation under low sliding speeds.
Low vibration, low noise and non-pollution in operation.
PTFE is transferred to the mating shaft to improve running properties.
Can be used in low hardness of mating shaft, so the shafts processing is easy.
The machine will be compact because of the thin thickness and low weight of the bush.
Electro plating is possible to prevent corrosion.
TYPICAL APPLICATIONS: Bronze based Pb-free oiles dry bearing TSB-1B is widely applied in Metallurgical industry, continuous casting and rolling mill, concrete machinery and spiral conveyers etc.
