Rotary Seals
Rotary seal
Rotary seals are active sealing components that can be used in hydraulic and pneumatic applications. These types of seals are produced in different variants and are predominantly used in dynamic and rotary movement applications. The sealing function is supported by the acting system pressure.
Tortef TK
The Tortef TK is an external, double-acting sealing element which consists of a PTFE seal and an elastomer O-ring as preload element. The Tortef TK is suitable for swiveling movements with high pressures and relative slow rotating movements. Particularly suitable for tooling machines, swivel motors, axis and shafts with rotating and swiveling movements.
The PTFE compound is filled with bronze or carbon graphite to improve the compressive strength. Further materials upon request. O-rings are available in a variety of different materials.
