Shaft Seals

With internally protected sealing lip. With O‑ring for sealing in the groove base. For high peripheral speed and increased chemical resistance

High pressures at relatively low speed. For fluids over a wide viscosity range and for gases. Rotary unions at high pressure. Robot axes

High termat or chemical specifications. Medium pressure and low speed. Suitable for almost all fluids. Robat axes, Rotary unions.

Types 231 to 238 are used for lubricating fluids and to a limited degree also for dry running and purely rotary or oscillating motion. They are only partly suitable for helical motion.
