The KB05 Profile is used in pneumatic sealing systems where low friction and high sealing performance are critical. The low footprint, radiused sealing lip gathers fluid film and the undercut on the outside diameter locks in initial lubrication. These features are unique in pneumatic rod seal design and help to considerably lower frictional values.
The seal is manufactured with an interference fit along the inside diameter which provides it with excellent stability in the groove while it reciprocates against the cylinder bore.
The KB05 profile is available in a variety of our high-performance materials, but our lubricated polyurethane s are most common due to the extra lubrication and abrasion resistance provided.
