Product Description

High quality KDAS hydraulic oil seal for mechanical Engine seal

Description-Hydraulic Oil Seal:

Hydraulic seals are generally made from elastomers, natural and synthetic polymers, which possess weak molecular attraction and highly elastic properties. Two major sources for hydraulic seals are rubber and plastics (including PTFE and polyurethane). Other elastomer materials used to fabricate seals include butadiene, nitrile, butyl, and silicone. Seals made with these and other elastomeric materials are usually fabricated through extrusion, although hydraulic seals are sintered in an oven from a powder form.

Seals may also be made from non-elastic materials such as felt and leather. Some particular types of hydraulic seals (e.g. bonded seals) are made from metallic materials (including brass, bronze, aluminum, carbon steel, and stainless steel). All of the metal materials used to create seals may be plated or galvanized for added oxidation protection and strength. The adhesion between the rubber material and metal of a bonded seal is created via chemical bonding.

Major Types and Operations:
Hydraulic seals are most often found in hydraulic cylinders, the mechanical actuators that convert hydraulic pressure (from oil, water, or another pressurized fluid) into unidirectional force for agriculture and forestry vehicles, construction equipment, and similar mechanisms.
Usually, hydraulic seals are located on the cylinder head, on the rod shaft, or in the piston. In these positions, seals keep fluid from leaking past the interface between the rod and head, from leaking to the outside of the cylinder, and from flowing across the piston.

Hydraulic seals are divided into two main groupings: static and dynamic.

Major Types	Operations
Static seals	Static seals are typically located in grooves and other confined spaces, where they act as gaskets. In this context, the term gasket refers to a mechanical seal that fills the space between two or more mating surfaces that do not have any motion between them and is held in place by pressure applied by the tightening of bolts. Although static seals vary by number and exact location depending on the specific cylinder structure, all of them serve the purpose of closing gaps between immobile surfaces. Static seals can be further broken down into groups of axial static seals and radial static seals. To achieve a secure seal, axial static seals must be squeezed between their upper and lower surfaces. Radial static seals, on the other hand, accomplish the same thing when they are compressed between their inner and outer surfaces.
Dynamic seals	Dynamic seals are also known as shaft seals, seal gaps between two surfaces that do share relative motion. Types of motion they work in between include reciprocation, oscillation, and rotation.
Reciprocating dynamic seals	Reciprocating dynamic seals are seated within glands that hold relative motion. Here they move along an axis in between inner and outer surfaces. Most often, they're used to power linear actuators, hydraulic cylinders, and pistons in internal combustion engines.
Oscillating seals	Oscillating seals operate with shafts that rotate using a limited number of turns around its axis. Because of the frequency with which these shafts rotate, oscillating seals are usually made of a relatively hard material and have self-lubricating capabilities.
Rotary seals	Rotary seals are placed where a hydraulic device experiences rotational motion from a housing and a shaft.
