Poor lubrication or hydraulic cylinder aperture processing tolerance. When the hydraulic cylinder piston cylinder Gansu prices, friction will be when the big, small, slip or crawl. Pre-ground approach is to exclude the cylinder, then with the requirements formulated in the piston cylinder, grinding rod, configuration guide sleeve. Seal of quality and sliding or crawling are directly related. O-rings when used at low pressure, with the U-shaped ring relatively Henan 200 t hydraulic cylinder, due to the high surface pressure, the larger the difference between static and dynamic friction Shandong 300 tons hydraulic cylinders, prone to slip or crawl; U-type seal surface pressure increases with increasing pressure, although the sealing effect have been increased, but the difference between static and dynamic friction also increases the internal pressure increases, the impact of rubber elasticity, the contact resistance increases lip seal ring will rollover and lip elongation, it tends to cause slippage or crawl, to prevent its tipping support ring can maintain its stability. Jiangsu hydraulic cylinder manufacturers, hydraulic cylinders, hydraulic pressure is provided by the Texas Aerospace Dezhou City aerospace hydraulic machinery plant.
