Detailed Product Description

SF-1T(SF-1TW,without lead Pb) is proved from SF-1 and special designed for hydraulic pressure gear pumps. It is wrapped bearing made of triple layer composites:
low-carbon steel as base, porous bronze interlayer and PTFE surface layer.

The products are widely used in machinery industry, such as medium and high pressure gear oil pumps, vane pumps, ram pumps, etc.

Features:

1. Low friction coefficient,

2. Anti-wear and anti-corrosion

3. Able to be used without oil
4. Low vibration, low noise. compact and light

5. Working temperature range: -195^oC~+280^oC

6. Size from 0606 to 150100
