The externally sealing double-acting OQ rotor sealing set featuring a Slipper Seal® design consists of a PTFE rotor sealing ring and an an elastomer O-ring as a preloading element.
It is particularly suitable for alternating sealing of rotary transmissions for slewing rings, swivel drives, hose reels, and in machine tool hydraulics. If the sealing set is used as an end seal, it is recommended to install a double wiper ring at the end of the components. Due to the special operating conditions of rotary transmissions, the OQ rotor sealing sets are provided with one or two circumferential lubrication grooves.
Due to the material combination of the slide ring (PTFE) and O-ring (elastomer), this product is suitable for a wide range of applications, especially for aggressive media and/or high temperatures. Alternatively, several compounds can be selected, depending on the specific applications profile.
From the perspective of application engineering, internally sealing rotor seals (see RS, OR, KA product series) are the preferred choices.

• 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.
