Product catalog summary
Overview: The document describes the AI-D double wiper, an elastomer wiper designed for hydraulic cylinders. It is compatible with the standard AI wiper housing and features an inner diameter wiping lip to retain minimal oil films and prevent dust and dirt adhesion on piston rods.
Specifications: The AI-D wiper is recommended for use with rod sealing systems of the slide and O-ring type but can also be used with lip seals. It is suitable for a temperature range of -45°C to +120°C and a sliding speed of up to 1 m/s.
Materials and Design: The document lists materials such as RUP and pure-EFTP as alternatives upon request. Design hints include bending the wiper into a kidney shape for fitting into grooves.
Surface Finish: Sliding surfaces should have a surface roughness (Ra) between 0.1 to 0.3 µm and a maximum Rt of 1.5 µm. Groove base and sides have specific roughness requirements as well.
Dimensions and Ordering: The document provides a comprehensive table of dimensions for the AI-D wiper, ranging from diameters of 14 mm to 500 mm. Each entry includes reference numbers for ordering. Further dimensions are available upon request.

Doppelabstreifer, innenabstreifend Double Wiper, inside wiping AI-D Doppelabstreifer, innenabstreifend Double Wiper, inside wiping Der Doppelabstreifer AI-D ist ein Elastomerabstreifelement, das einbaugleich zum Standardabstreifer AI verwendet werden kann. Durch die am Innendurchmesser angeordnete dichtungsseitige Abstreiflippe wird gewährleistet, daß selbst minimalste Schleppölfilme im System verbleiben, und die ausfahrende Kolbenstange Staub und Schmutzpartikeln keine Möglichkeit mehr zur Anhaftung bietet. The double wiper AI-D is an elastomer wiper that can be used in the same housing as the standard AI wiper. The wiping lip at the inner diameter of the seal so ensures that minimum leakage oil films remain in the system, and prevents dust and dirt particles from sticking to the extending piston rod. Der Doppelabstreifer AI-D empfiehlt sich besonders in Verbindung mit Stangendichtsystemen der GleitringO-Ring-Bauform. Er kann auch problemlos mit Nutringen eingesetzt werden. The double wiper AI-D should generally be used in combination with rod sealing systems of the slide and O-ring type. However, they may also be used with lip seals without any problem. 195
