3. Application
ROHS Straight & Flange Carbonsteel PTFE Sleeve Bearings Lead Free are widely used in aerospace,petroleum machinery,military enterprise etc.
4. Advantages
This products offer very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions & have good mending,low-noise,non-pollution, low coefficient of friction long operating life.Sintered layers are of special copper alloy containing uniformly dispersed solid lubricants,the lubricant is more lubricated because it is dispersed on the working surface.Suitable for hostile environments,for high load application which lubrication is difficult.
