Hydraulic And Pneumatic Seals

Hydraulic sealsare essential components used in hydraulic systems to prevent fluid leakage and maintain system integrity. They are designed to create a tight seal between moving parts, such as pistons and cylinders, within hydraulic machinery. There are several types of hydraulic seals, each designed for specific applications and operating conditions.

Some common types include:

O-rings O-shaped seals that are widely used due to their simplicity and effectiveness. They fit into grooves and provide a reliable seal between two surfaces.

Piston Seals:

RThese seals are specifically designed for dynamic reciprocating motion, such as in hydraulic cylinders. They are positioned on the piston head and prevent fluid from bypassing the piston as it moves.

Rod Seals:

Rod seals are installed on the outer circumference of the piston rod and prevent fluid from leaking between the rod and the cylinder wall during reciprocating motion.

Wiper Seals:

Wiper seals are used to clean the piston rod surface and prevent dirt, debris, and contaminants from entering the hydraulic system. They are usually installed in conjunction with rod seals.

Guide Rings/Bearing Rings:

These seals provide support and guidance to the piston rod, ensuring smooth movement and preventing metal-to-metal contact.
