Types of Seals

There are many types of seals, which can be selected according to different usage requirements and working environments. Here are several common types of seals..

VType Seal: This is an axially acting elastic rubber seal used for pressure-free sealing of rotating shafts. The sealing lip has good mobility and adaptability, can compensate for large tolerances and angular deviations, prevents internal grease or oil from leaking out, and also prevents external splashes or dust from entering.

UType Seal: Commonly used for reciprocating seals in hydraulic systems. Widely used in the sealing of hydraulic cylinders in engineering machinery.

OType Seal: Mainly used for static seals and reciprocating motion seals. When used for rotating motion seals, it is limited to low-speed rotating sealing devices.

Rectangular Seal: Generally installed in grooves with a rectangular cross-section on the outer or inner circle to serve as a seal.

YType Seal: Widely used in reciprocating motion sealing devices. In addition, there are spring tension (spring energy storage) seals, which are made by adding a spring to thePTFEseal material, withOtype springs,Vtype springs,Utype springs.
