One of the primary functions of a dust wiper seal is to protect the internal components of a system from abrasive particles that can cause wear and tear. For example, in a hydraulic cylinder, dust wiper seals help prevent dirt and debris from entering the system, which can cause damage to the piston rod and cylinder wall. By creating a barrier between the internal components and external contaminants, dust wiper seals help maintain optimal performance and efficiency.

Additionally, using OEM (Original Equipment Manufacturer) seal kits ensures compatibility with your specific excavator model. While aftermarket options may be tempting due to lower prices, they often come with risks such as improper fit or subpar material quality that can lead to premature 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.
