K17
K 17 is a two piece double acting piston seal which consists of one special mixture PTFE profile ring and an o-ring as energizing element.
-
Low friction , free of stick-slip
-
Simple groove design and low axial housing heights
-
Long service life
-
High sliding speed
-
Wide range of temperature and chemicals depending
on the o-ring material -
Minimum static and dynamic friction coefficient for a
minimum energy loss and operating temperature -
Wide range of dimensions
Injection moulding machines, fork-lift trucks, loading platforms, cranes, agricultural machinery and valves for hydraulic and pneumatic systems
We recommend using special assembly tool and to have open groove design for dimensions that are smaller than Ø 40 mm. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.
note: It is recommended to have 50% to 90% of the working surface material contact area value
