Range of seals

Other seals

For non-standardized products, we offer a diverse range of alternative solutions. Whether for products which have been turned, punched or cut with a water jet, we have a solution for almost every problem;  i.e. the right seal. If you provide us with the corresponding quantity and material requirements, we would be glad to make you an offer. It would also be extremely helpful if you could send us a drawing of the required product.

Sheet material in a diverse range of geometries, cords, radial shaft seals, rubberized metal parts and metal O-rings, as well as special custom solutions according to drawings provided are as much a part of our daily work as working with special materials in highly specialized areas of application (e.g. Kalrez, FEP – coated rings, synthetic products made of PTFE, PA, PE, POM or PEEK).

Do you require O-rings in custom sizes? We have just the right solutions for you. Sizes up to 1300 mm are possible with tool or segment processes. We also offer larger dimensions as RSTV variants.

Piston seal ADAD-4-30/+100Download PDF

Scraper rings serve to prevent the ingress of dust, dirt, grains of sand and metal filings into axially-driven rods and plungers. This allows them to prevent the formation of grooves to a large extent, protect the guide components and seals, and thus extend the service life of the seal system.

Profile AD consists of a PTFE ring that carries out the scraping and an elastomer O-ring as a preloading element. It unites two functions: Scraping to counteract external dirt and a sealing function that reduces the residual oil film.

Due to the combination of materials used in the sliding ring (PTFE) and the O-ring (elastomer), this product is suitable for a wide range of applications, in particular for aggressive media and/or high temperatures. A comprehensive selection of materials is available for individual application profiles.

Piston seal OROR3001-30/+100Download PDF

Manufacturers of swiveling bushings often request that the seal design be simplified. This can be done with the use of internally-sealing OR rotor seal kits.
The seal kit OR consists of a low-wearing sliding ring characterized by its low friction, and an elastomer O-ring as a preloading element.

It is especially suited to the two-way sealing of swivel bushings for rotating assemblies, pivot drives and hose reels, and for applications in machine tool hydraulics. If the seal kit is used as a final seal, it is recommended that the construction be closed off with a scraper ring.

In order to meet the demands of the special operating conditions of swiveling bushings, the rotor seal kits OR are equipped with one or two circumferential lubrication grooves.

Piston seal OQOQ3001-30/+100Download PDF

Currently only available in English

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 and 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 should the profile OQ be considered.

Depending on the special working conditions, the rotary sealing set OR is equipped with one or two circumferential lubricating grooves.
