Germany MERKEL pneumatic compression type seal seal -KDN

1. Material
    Hardness: 72 Shore A NBR
    Grade: Simrit 72NBR708

2. Operating conditions
    Media: treated and dried, compressed air without lubricant (grease-coated after assembly).
    Working pressure: ≤1MPa (10bar)
    Temperature: -20 ℃ ~ + 100 ℃
    Line Speed: ≤1m / s

3. Features
     Bidirectional Clamp pressure seal side grooved.
     Compact so that it can be used for small section of the piston (such as short-stroke cylinder).
     Circular sealing surface and a soft middle portion provides low friction and maintain an effective lubricant film a good seal.

4. trenches and machine processing standards
    Cylinder: Rmax≤4μm, Rp / Rz <0.5
    tp (25% Rmax) = 50% ~ 75%
    Trench floor: R max≤10μm, Rp / Rz <0.5

5. Install
    Careful installation is to ensure a good seal function prerequisites.
    Clamp seal KDN removing burrs from the edge of the piston into the cavity withhold groove.
