Swivel Seals

Swivel Seals

Swivel seals are designed for slow rotary applications, such as the hydraulic swivels, which allow the transmission of pressurized services between the chassis and body of mobile hydraulic equipment.

    The Hallite 80 rotary pressure seal is a seal designed specifically for use in hydraulic swivel joints.

    The Hallite 80 is manufactured in Hallite’s high specification polyurethane, Hythane 181, to provide ease of installation and excellent sealing characteristics.

    Please call your local Hallite sales office for further details.

    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.

    NB: Part numbers suffixed by “‡” indicate housing sizes to meet ISO7425-2.

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

    A patented seal designed specifically for hydraulic swivels. Manufactured in the high grade Hythane® 181, Hallite’s Ro800 is engineered as a one piece seal. No relative motion between the seal and the energiser can effect the lifetime of this seal, which is often mainly the problem of two piece swivel seals.

    The special design of the Ro800 is minimizing the friction.

    Optional anti-extrusion rings made from acetal are allowing larger extrusion gaps. The seal without anti-extrusion rings are made for applications with a very good guidance or low working pressure. Therefore please contact our technical service.

    Ro800 is designed for double acting conditions. Designs are available for piston or rod applications.

    The seal is easy to install in one piece housings.
