One of the primary functions of the dust seal is to protect the internal components of the hydraulic cylinder from abrasive particles that can cause wear and tear. When these contaminants enter the system, they can cause damage to the piston rod, cylinder barrel, seals, and other critical components. This can result in leaks, reduced performance, and ultimately, system failure.

Shaft oil seals typically consist of a flexible sealing lip made from elastomeric materials such as rubber, polyurethane, or silicone, encased in a sturdy outer shell. The sealing lip makes contact with the rotating shaft, creating a barrier that effectively retains lubricants while blocking unwanted particles. The design may include additional features such as garter springs to maintain contact with the shaft and improve sealing effectiveness over time.
