Germany MERKEL pneumatic piston ring seal -AIRZET PK
1. Features
Able to work under pressure, the pressure side with a two-way Clamp ring groove. Compact piston can be used to make short axial dimension (eg short-stroke cylinders). Rounded sealing surface and a soft center portion provides low friction and maintain an effective lubricant film a good seal.
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
Nitrile rubber (NBR)
Hardness: 80 Shore A
Grade: 80NBR 245001 (MB219)
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 ring AIRZET PK removing burrs from (edge rounding) of the piston into the cavity edge withhold groove.
