RS91B

Function
Rod seals are designed to seal the pressurized hydraulic fluid against the atmosphere,
preventing leakage and pollution of the environment.
Features

• Asymmetrical, single acting rod seal, designed with interference of the preload

• High pressure force because of a machined rubber preload element.
• Less relative movement of the rubber part compared to an O-Ring giving the seal

• Excellent sealing performance in low and high speeds.
• Suitable for positioning functions.
• Negligible tendency to “stick-slip” effect, good sliding properties.
• Low break-away load after long standstills.
• Excellent gap extrusion resistance due to the free space on the trailing side.
• Can be used in grooves where no O-Ring is possible.
