Design

The Hallite 310 rotary pressure seal is designed specifically for use in hydraulic swivel joints.

The seal assembly consists of a carbon filled PTFE seal ring energised by an NBR O ring.

For aggressive media an FKM O ring can be substituted. The face material and design provides high abrasion resistance and low friction to allow running at low rotational speeds with minimal stick-slip.

The low friction is helped by the groove in the sliding face, which provides an oil reservoir.

The groove also reduces the contact area with the rotating counterface and allows a higher contact pressure.

The circular recess in the outer diameter increases the contact of the face with the O ring and minimises the possibility of the sealing components rotating relative to each other.

Features

  • Minimal stick-slip
  • Very low friction
  • Can be mounted into one piece housings (over
  • 30mm rod diameter)
  • High temperature capability
  • Low counter face wear
  • Good extrusion resistance
  • Compact housings- small installation space

Note :

When the Hallite 310 is used as an end seal,it is recommended that it is protected with a wiper.
