DanaGlide R01

The DanaGlide rod seal is designed for double-acting applications with small groove dimensions and provides extremely high form stability against extrusion throughout its service life. In dynamic applications, the seal rides on a lubricating media film, which extends the service life. The media film moves from the low-pressure side to the high-pressure side. This is not a leakage as such.

With Dana-Seals low-friction materials and good lubrication, extremely favourable friction values can be achieved. To ensure that the profile ring is pressure activated even in conditions with rapid pressure changes, the seal can be delivered with notches.

O-rings may limit the temperature range and need to be compatible with the media.

The performance of the seal will always depend on the overall picture of the working conditions.

Verification can only be done by testing the seal in the actual working conditions.

Max radial clearance is based on DanaFlon 24 and 100 °C
For other hi-filled Danaflon compounds the clearance should be reduced with 10%
Clearance: At Pressure > 40 MPa use diameter tolerance H7/f7 (Bore/Rod)
