The OQ rotary sealing set consists of a wear-resistant, low-friction PTFE slipper sealing ring and an elastomer o-ring as a preloading element.
It is suitable mainly for applications where the pressure alternates from one side of the seal to the other, such as pivots for rotating track rings, swivel joints, hose reels, and in machine tool hydraulics. If the sealing set is used as an end seal, it is recommended to install a wiper ring at the end of the components. Based on friction conditions during rotating movements in the application, the sealing set profile OR should generally be preferred. Only if housing limitations are given the profile OQ should be considered.
Depending on the special working conditions, the rotary sealing set OR is equipped with one or two circumferential lubricating grooves.

• Excellent wear resistance.
• Minimal break-away and dynamic friction and no stick-slip tendency ensures uniform motion even at low speeds.
• Good energy efficiency due to low friction.
• High temperature resistance assured by suitable O-ring compound selection.
• Adaptable to nearly all media thanks to high chemical resistance of the sealing ring and large O-ring compound selection.
• Dimensions according to DIN ISO 6195, Type D.
• Installation in closed and undercut housings.
• Available in diameters from 4 to 3000 mm.
• Machined small-volume series and samples available with short lead times.
