CR Seals has one of the longest histories in the seal industry. For the last 110+ years, CR Seals has been setting performance and service life standards for industrial and automotive shaft seals. CR Seals has also been part of SKF since 1990, a span during which they have developed new materials, manufacturing processes and designs to create some of the most robust seals on the market. CR Seals is represented as Power Transmission Seals in SKF.
Radial Shaft Seals
Radial shaft seals sit between rotating and stationary components, or two components in relative motion. They have two main parts. One is a cylindrical outer covering with an interference fit that seals statically against the housing bore. The second, a sealing lip, seals dynamically and statically against the shaft. Its sealing edge presses against the counter face surface of the shaft with a defined radial load.
V-ring seals are axial shaft seals, available in a wide range of stock sizes and customized solutions for sizes above 2 000 mm or special requirements
This thin-walled sleeve [0,28 mm (0.011 in.)], developed by SKF, is simply pushed in position over the worn area, providing a counter face surface that is optimized for radial shaft seals.
