Germany MERKEL seal -AIRZET PR type pneumatic rod seal
1. Features
For driving pressure side bidirectional compression type seal with the trench. Its compact dimensions of the cylinder head can be reduced (such as short-stroke cylinder; also be used for the valve).
Rounded lip and soft central portion of the seal ring with low friction and maintain an effective lubricant film a good sealing function.
2. Operating conditions
Media: treated and dried, compressed air without lubricant (grease-coated after assembly).
Working pressure: ≤1.2MPa (12bar)
Temperature: -20 ℃ ~ + 100 ℃
Line Speed: ≤1m / s
3. Material
Hardness: 80 Shore A of NBR rubber.
Grade: 80NBR 24500 (MB219).
4. trenches and machine processing standards
Piston rod: Rmax≤4μm, Rp / Rz <0.5
tp (25% Rmax) = 50% ~ 75%
Trench floor: R max≤10μm, Rp / Rz <0.5
5 Installation
Careful installation is to ensure a good seal function prerequisites. Clamp ring AIRZET PR from the rounded edge of the cavity into the cavity withhold groove.
For less than 15mm diameter rod, it requires the use of up to the axial direction of the cavity. (Open trenches)
