Floating seals are developed as a seal for track rollers of construction machines and mining machinery. As its name suggests, the floating seat is installed not to contact with the shaft and keeps sealing performance by the tightening force and elastic distortion of the O-ring. Therefore, floating seal is most appropriate to seal sand and dirt, and is widely used for axles, drill heads, final drives, idlers, mobile track systems, mining equipment, pumps, rollers, tunnel boring cutters and undercarriages.

Floating seal is a special form of mechanical seals. This seal consists of the O-ring or Elastomer Packing and the floating seat, made of special cast steel or other wear resistant materials.
