Elastomeric bellow seals with market price factory in China

The utilization of an elastomeric bellow as an auxiliary seal to the shaft has a few advantages for the design of a mechanical seal. In this manner the bellow acts as a complex central component part, which also performs different undertakings other than its sealing function. One of these assignments is the transmission of the friction torque from the sliding surface to the shaft as well as the retaining and sealing of the seal ring inserts. A lot amounts in production allow low manufacturing cost at a high technical quality. What's more, automatic adjustment compensates for abnormal shaft-end play and run-out, essential ring wear and equipment tolerances. Axial and radial shaft movement is compensated for with uniform spring pressure.
