The designation 20x35x7 refers to the dimensions of the oil seal. The numbers represent the inner diameter (20 mm), outer diameter (35 mm), and the thickness (7 mm) of the seal. The design of an oil seal is critical, as it must fit precisely to ensure a proper seal and prevent the ingress of dirt, dust, or moisture. The choice of material used for these seals often includes rubber compounds that enhance flexibility and resilience. Common materials include nitrile rubber (NBR), fluorocarbon rubber (FKM), and silicone, each chosen based on the specific application and operating conditions.

2. U-Cups U-cups are designed to provide a reliable sealing surface on the rod and piston. The unique shape allows them to hold fluid under pressure while preventing leakage.

2. Low Maintenance These pumps have few moving parts, which translates to lower maintenance costs and a higher lifespan. Regular maintenance may only include checking for clogs or replacing worn-out parts, making them an ideal solution for remote areas.

1. O-Rings These are one of the most common types of seals, offering simplicity and effectiveness. They can be used in static applications, but with proper design, they can also function well in dynamic environments.

One common type of oil seal is the lip seal, which features a flexible lip that makes contact with the rotating shaft to create a tight seal. Lip seals are often used in automotive engines, gearboxes, and industrial pumps due to their effectiveness in preventing oil leaks. Another popular option is the mechanical seal, which uses a rotating element to maintain constant contact with the shaft, ensuring a reliable seal even at high speeds and pressures.

3. Disassemble the Cylinder Carefully remove the cylinder from the machinery. Using appropriate tools, disassemble the cylinder, taking care to note the arrangement of components.

A rotary shaft seal, also known as a lip seal or radial seal, is a device that creates a barrier between two environments the area where the rotating shaft operates and the external atmosphere. In high-pressure applications, these seals are engineered to withstand significant operational pressures, often exceeding several thousand psi. They are utilized in applications such as hydraulic pumps, turbines, and engines, where preventing fluid loss is critical.
