ROD SEAL KO1

STANDARD SEAL DIMENSIONS

DESCRIPTION

The KO1 seal type has been developed to replace or work jointly with stepseals in PTFE, because of the same groove dimension. Internally it has a round groove where an O-ring, can be inserted and housed. The O-Ring acts as energizer for the static and dynamic sealing lips even without pressure. This profile has also excellent results at very low speed and pressure, because of the low friction. The machining of the groove is easier thanks to the reduced axial dimension.

TECHNICAL DATA

Pressure: < 250 bar at a temperature of 60° C Speed: < 0.5 m/s Temperature: from - 35° C to + 100° C, with peaks till 110° C Fluids: mineral oils (see TABLE I, pages 12-13)

MATERIAL

The proposed material is polyurethane, with high elasticity modulus, low compression-set and high abrasion resistance. The hardness is 93 Shore A ± 2, energized with
O-ring in NBR 70.

ASSEMBLING

As for all seal housings, remove any flash or cutting edges.
