Hydraulic piston rod seals

PN 02 9275.1
 

Material: PU 80
Application: hydraulic seal
Operating pressure: ≤ 160 bar
Radial clearance: ≤ 0.2 mm
Operating temperature: -30 °C to +80 °C
Feed rate: ≤ 0.5 m/s
Design: Single-acting piston rod

Piston-type sealing sleeve for hydraulics. Asymmetrical shape
with a pre-set outer cutting edge optimizes the tigh fit in the groove and ensures durability even under severe conditions. PU guarantees a long service life.

Design: Single-acting piston rod

Piston-type sealing sleeve for hydraulics. Asymmetrical shape with pre-set
outer cutting edge optimises a tight fit in the cylinder head groove.  Second cutting edge,
oriented towards the sliding surface, ensures minimal play even at zero pressures.
and the durability of the cuff even under extreme conditions.  The PU material guarantees
long service life.
