KDSA PISTON SEAL
DESCRIPTION
In the compact seals two profiles are available: KDSA and KDSB. KDSA Piston Seal is composed of a central unit made of nitrilic rubber working as a seal, two side supports, working as anti-extrusion rings, and two external guide rings, keeping the piston position in the cylinder aligned.
TECHNICAL DATA
Pressure: from 0 to 300 bar with peak still 400 bar at 60°C
Speed: <0.5 m/s
Temperature: from -30°C to +100°C
Fluids: Mineral oils
MATERIAL
The compounds used to manufacture this seal type are the following:
– the centralun it is made of NBR , the hardness is 70 Sh A ± 3
– the side supports are made of thermo plastic elastomer (TPE)
-the external wearrings are made of polyacetalic resin (POM) Compound reference: CX
ASSEMBLY
The assembly of this seal can be carried out in either closed groove, on a monobloc piston, or in open groove, on a two-part piston. The assembly order is as follows:
- rubber element;
- supports;
- wear rings.
The piston must not have machining scores which might damage the rubber unit during the installation.
