Fuld produktbeskrivelse

The Ultrathan® piston sealing set KR complements the product range of double-acting piston seals (OE, OK) for grooves according to ISO 7425-1 by a product which is preferably used in the medium-duty pressure range up to a maximum of 300 bar. The sealing set stands out by its extreme wear resistance and exceptionally high static and dynamic sealing performance and can also be used for piston accumulators.
The KR sealing set consists of a polyurethane slide ring with improved sliding properties and particularly high modulus and an energizer with rectangular cross-section made of an NBR elastomer.

• Exceptionally high static and dynamic sealing performance.
• Good sealing performance in extremely small assembly conditions.
• Can also be used for single-acting applications.
• Robust seal profile for harshest operating conditions.
• Extreme wear resistance.
• Long service life thanks to application-optimized compounds.
• Constantly low dynamic friction throughout the part's service life.
• Easy snap assembly on a single-part piston.
• Insensitive to pressure peaks.
• Functional reliability at critical temperatures.
• High extrusion resistance.
• Dimensions according to ISO ­7425-1.
• Short axial assembly length.
• Installation in closed and undercut housings.

Range of application:
The KR piston sealing set is suitable for use in all standard industrial cylinders, farming equipment, light construction machinery and mobile devices. Due to its exceptionally high dynamic sealing performance, it is particularly well suited for leakage-critical applications.
