Hebei Hankai hydraulic seal

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.

In addition to preventing leaks, the oil seal also plays a role in protecting the hydraulic system from contaminants. Dust, dirt, and debris can easily enter the hydraulic system without a proper seal, leading to wear and tear on the components and potentially causing the system to malfunction. The oil seal creates a barrier between the internal components of the cylinder and the external environment, ensuring that the hydraulic system remains clean and efficient.

Durability is a key factor, as machinery often operates in harsh conditions. High-quality oil seals can handle extreme temperatures and pressures, further enhancing their lifespan and reliability. Regular maintenance and inspections can extend their service life, ensuring that machinery operates smoothly.

High Pressure Rotary Seals An Overview

Hydraulic cylinders work by converting hydraulic energy into mechanical energy. As hydraulic fluid is pressurized within the cylinder, it pushes against a piston to create motion. The seals in the cylinder seal kits play a vital role in this process. They ensure that the hydraulic fluid does not escape the cylinder and that outside contaminants do not enter, which could lead to wear and tear.
