In the field of sealing components, Glyd rings and step seals are commonly - used combined sealing elements, widely applied in equipment such as hydraulic cylinders. Mascot, focusing on sealing solutions, provides an analysis of the differences and applications between the two.
Composed of a rubber O - ring and a polytetrafluoroethylene (PTFE) ring. The O - ring exerts force and acts as a double - acting piston seal, featuring low friction, no stick - slip, small starting force, and high pressure resistance. It is divided into bore - used and shaft - used types. Relying on its own deformation, it generates an initial contact stress to prevent the leakage of non - pressure liquid. When the hydraulic cylinder is in operation, the pressure liquid squeezes the O - ring, making the square sealing ring closely adhere to the sealing surface. The additional contact stress and the initial stress jointly prevent leakage. It needs to be used with a guide support ring, and a split groove is suitable when the cylinder diameter is less than 40.
Also composed of a rubber O - ring and a PTFE sealing ring. The O - ring serves as a force - exerting element and also has a compensation function. It is suitable for the sealing of piston rods of hydraulic cylinders and is a single - acting seal. It is divided into piston - used and piston rod - used types, and the applicable media include hydraulic oil, gas, etc.
Glyd rings can achieve two - way sealing and perform well in high - pressure scenarios. Step seals are single - acting, with low dynamic sealing friction, good chemical resistance, and compatibility with various media. They have characteristics such as low deformation rate and no stick - slip movement tendency, and their structure saves space.
For high - pressure, high - speed, and high - temperature hydraulic systems, Glyd rings have a high degree of adaptability. For occasions requiring corrosion resistance, high - temperature resistance, and self - lubrication, step seals have significant advantages. Mascot provides Glyd rings and step seals in various specifications and materials, suitable for different customer needs, and helps you with the selection for sealing applications.
