What are Wiper Oil Seals?

Structure and Design

A rotary lip seal typically consists of two main parts the elastomeric sealing lip and the metal or plastic casing. The sealing lip is made from materials such as rubber, polyurethane, or silicone, chosen for their resistance to wear, temperature fluctuations, and chemical exposure. The metal casing provides structural support and is designed to fit snugly onto a rotating shaft.

5. Backup Rings These rings are used in conjunction with O-rings to prevent extrusion under high pressure, providing additional protection to the sealing system.

Cylinder gland seals are prevalent in various industries, including construction, manufacturing, aerospace, and automotive. Their primary function is to maintain system efficiency by reducing fluid loss, thereby minimizing energy usage and operational costs. Furthermore, effective seals contribute to the safety and reliability of machinery, reducing the risk of failure that could lead to accidents or costly downtime.

2. Static Seals These seals are designed for applications where there is no relative motion between the sealing surfaces. They are often used in hydraulic cylinders and various types of machinery where oil containment is critical.

2. Material Composition Oil seals are typically made from various elastomers like nitrile rubber (NBR), fluoroelastomer (FKM), or silicone, depending on the application requirements. The percentages could also hint at the ratio of different materials used in the seal to enhance its performance in specific environments, such as high temperatures or chemical exposure.
