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