Floating seal 1:Floating seal is high efficiency mechanical dust seal which owns several characters, such as good stain resistance, high wearing resistance, shock-proof, long durability, easy installment, reliable performance and auto compensation etc. It can apply for the special machinery which work in the hard condition, such as construction machinery, coal mining machinery, mining machinery, auto car etc. 2:Technical parameter: 1. Working time: 3000H. 2. Rigidity of working area: HRC60-72. 3. Precision of working area: ≤ RAO.1μm. 4. Plainness of working area: ≤ 0.002μm. 3:Production skill and Performance: Reasonable quench processing and good performance for high anti-wearable and anti- tiredness, which make the more longer in life-span so that obtain the favorable cost- efficiency, including save the oil for 3%.Even if suffer from the cautery, dramatically change In temperature (From -20 to +110 ), meeting the pressure reaching 4kg/cm2 and high contacting-speed function, they can maintain the stability.
