This type of rotary joint is applied in situations with low rotational speed and high pressure.

This is achieved through the combination of a radial ring-shaped sliding seat and an O-ring seal. The O-ring provides static sealing, while the ring-shaped sliding seat provides dynamic sealing.

This combination form results in a smaller friction force and less sealing and wear. Moreover, it is necessary to prevent the supply of fluid in a non-rotating condition, which could cause damage to the sealing components.

The rotor is made of surface-hardened and ground stainless steel, capable of withstanding slight friction.

Can be used with air, maximum pressure 10 kilograms, maximum rotational speed 300 revolutions per minute.

It can use hydraulic oil. The maximum pressure is 300 kilograms and the maximum rotational speed is 300 revolutions.
