Dust Seal

Dust seals are used in critical areas of excavators such as hydraulic cylinders, bearings, and transmission systems to prevent dust, dirt, moisture, and other contaminants from entering the interior of the system. In hydraulic systems, dust seals are usually installed between the piston rod and cylinder barrel of a hydraulic cylinder to prevent external dust and impurities from entering the inside of the cylinder.

Dust Seal Material

Dust seals are typically made from durable, wear-resistant materials designed to withstand harsh environmental conditions. Common materials include rubber, polyurethane, and sometimes thermoplastic elastomers. Rubber dust seals, often made from nitrile or silicone rubber, offer excellent flexibility and resistance to abrasion, making them suitable for a wide range of temperatures and pressures. Polyurethane dust seals are known for their superior mechanical properties, including high tensile strength and excellent resistance to wear and tear. These materials are chosen for their ability to create a tight seal, preventing contaminants like dust, dirt, and moisture from entering the hydraulic system. The material’s resilience ensures that the dust seal maintains its integrity and functionality over extended periods, even in demanding applications.

Replacing Wiper Seal on Hydraulic Cylinder

Understanding hydraulic cylinders is essential; these vital components in hydraulic machinery require regular seal replacement.
When it comes to hydraulic cylinders, many people are relatively unfamiliar with them. It is a kind of conversion equipment, mainly used in hydraulic machinery. However, in use, the seals in hydraulic cylinders need to be replaced due to aging damage. Firstly, dismantle the upper mould and the cylinder rod of the hydraulic cylinder to make it leave; secondly, dismantle the rear cover of the hydraulic cylinder and withdraw the piston rod, etc.; then dismantle the front cover, you can see the damaged seal; finally, according to the size of the grooves of the hydraulic cylinder, choose the appropriate dust ring replacement and installation will be fine.
