Overview:

The UN type seal is a unidirectional acting sealing element, mainly used for piston rod sealing in hydraulic cylinders. It has excellent characteristics in many applications, especially in construction machinery, automobiles, forestry and mining machinery, in harsh working conditions. In heavy load applications, it has very good effects when used with the RS type stern seal.

In addition to the above-mentioned advantages, such as good sealing effect and easy installation, this sealing element also has the advantage of low friction the low pressure range. When used for rotating shaft, it is a rotating shaft lip seal.

It is suitable for piston rod sealing and has a wide range of applications, in hydraulic equipment such as construction machinery, automobiles, forestry and mining machinery.
