Characteristics and performance

The Hallite 652 is a rod seal designed designed to provide a dry sealing solution specifically for heavy-duty longwall mining applications using water-based fluids. The design is also suitable for standard hydraulic oil applications.

The seal is manufactured in a polyurethane shell energised by a high quality O-ring, or in some cases a profiled NBR energiser as used in the Hallite 621 twin lip rod seal. The Hallite 652 also incorporates an acetal anti-extrusion ring to withstand side loads and extreme pressure peaks even with the extrusion gaps, which are the result of using remote plastic bearing strips like the Hallite 506 or 708.
