A wide variety of hub oil seal options are available to you, such as mechanical seal, oil, and hydraulic. You can also choose from rubber, silicone, and metal. As well as from standard, nonstandard. And whether hub oil seal is free samples, or paid samples.
There are 14,200 hub oil seal suppliers, mainly located in Asia. The top supplying countries are China (Mainland), Thailand, and South Korea, which supply 99%, 1%, and 1% of hub oil seal respectively.
Rod and buffer seals maintain sealing contact in sliding motion between the cylinder head and the piston rod. Depending on the application, a rod sealing system can consist of a rod seal and a buffer seal (fig. 1) or a rod seal only (fig. 2). Rod sealing systems for heavy duty applications typically consist of a combination of both seal types, whereas the buffer seal is arranged between the rod seal and the piston in the cylinder head. Rod seals determine the tolerance for the rod diameter d.
In addition to the sealing function, rod seals also provide a thin lubrication film on the piston rod that lubricates themselves and the wiper seals. The lubricant also inhibits corrosion of the piston rod surface. However, the lubrication film must be thin enough so that it returns to the cylinder during the return stroke.
Selecting profiles and materials for a rod sealing system is a complex task, considering all possible cylinder designs and application criteria. SKF supplies rod and buffer seals in many different profiles and in a wide range of materials, series and sizes, which make them appropriate for a wide variety of operating conditions and applications.
