Type A (non-dry running), applicable in the case of coolant. It is essential to ensure that the coolant continuously flows through and the rotating shaft is at a high speed.

The A08 series has a maximum pressure of 100 kilograms and a maximum rotational speed of 15,000 revolutions per minute.

The A10 series has a maximum pressure of 70 kilograms and a maximum rotational speed of 10,000 revolutions per minute.

This series allows air to pass through when the main shaft is not rotating.

The small-sized contact form reduces the friction force during the rotation of the balancing sealing ring to the minimum, enabling it to withstand the coolant.

The tungsten carbide seal can still achieve a very long service life even when using cooling fluids with lower filtration accuracy, but it is essential to ensure that the cooling fluid continuously flows through.

The spring is used to prevent turbulence and vibration caused by the fluid.

The selected high-speed and high-precision bearings can operate for a long time at high speeds.

All the components are made of anti-oxidation materials and pure water can be used during operation.
