J Hydraulic Seals – Dust seals

Description

Dust proof for rod in air cylinder under reciprocating movements or exposed valve rod.J wiper is a sealing element which used in hydraulic applications to obstruct all kinds of negative foreign particles to go into the cylinders. Standardized with the material of high performance PU 90±2 Shore A.

And it is can be = made of rubber material with good elasticity, and the sealing lip of the oil seal is also assisted by external forces such as springs. Its sealing mechanism is the same as that of lip seals, and it is installed in the sealing groove. Due to design requirements and manufacturing errors, etc. The formed interference forces the dust-proof ring to deform so that the dust-proof sealing lip is always close to the sealing surface, and produces a suitable initial contact stress on the sealing surface to prevent external impurities from invading the hydraulic transmission system.

Wiper Seals, also known as Scraper Seals or Dust Seals are primarily designed to prevent contaminants from getting into a hydraulic system.
This is usually achieved by the seal having a wiping lip that essentially cleans away any dust, dirt or moisture from the rod of a cylinder on each cycle. This type of sealing is crucial, as contaminants can potentially cause damage to the other components of the hydraulic system, and cause the system to fail.
