Hydraulic cylinder oil seal is a sealing device used to control the flow of oil inside the hydraulic cylinder. It mainly plays a role in preventing oil leakage and preventing dust from entering the hydraulic cylinder. The hydraulic cylinder oil seal is composed of a piston (piston oil seal), a piston rod (piston rod oil seal), a piston guide sleeve (guide ring), and an end cap. Its working principle is to prevent oil leakage in the hydraulic system through the interaction force between the sealing contact pairs.

Hydraulic cylinder oil seals play an important role in mechanical equipment, effectively preventing liquid oil or liquid from leaking from the inside of the equipment to the outside, reducing equipment wear and tear, and avoiding safety accidents caused by oil leakage. In addition, oil seals can prevent external dust and impurities from entering the interior of the equipment, protecting its normal operation. At the same time, oil seals can also reduce equipment vibration and noise, improve equipment efficiency and operational stability.

In short, hydraulic cylinder oil seals are an important component of hydraulic systems, which are of great significance for ensuring the normal operation of hydraulic systems and extending equipment life.

A hydraulic cylinder, also known as an oil cylinder, is a hydraulic system that drives a load through hydraulic pressure to achieve linear motion. It consists of a cylinder barrel, cylinder head, piston, piston rod, and sealing device. In order for the piston to move inside the cylinder, a path for oil to flow into and out of the cylinder body needs to be provided. In order to ensure a constant flow rate of the hydraulic cylinder, a sealing ring needs to be installed. The hydraulic cylinder has a simple structure and reliable operation. When used to achieve reciprocating motion, it not only eliminates the need for a deceleration device, but also has no transmission clearance and moves very smoothly. Therefore, it is widely used in various mechanical hydraulic systems
