DF310

Design Introduction

Kintowe DF310 swivel pressure seal is designed specifically for use in hydraulic swivel joints. The seal assembly consists of a carbon filled PTFE seal ring energized 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 roating counterfaceand 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 roating relative to each other.

Advantages

●High temperature capability
●Low friction, minimal stick-slip
●Low counterface wear
●Good extrusion resistance
