hydraulic gear pump seals

1. Pressure Resistance One of the primary attributes of high pressure rotary shaft seals is their ability to withstand significant pressure differentials. This feature is particularly important in hydraulic systems where the pressure can exceed several thousand psi.

Wheel bearing grease seals, often referred to simply as grease seals, are fitted between the stationary and rotating parts of a wheel bearing assembly. They create a barrier that prevents grease from leaking out while simultaneously keeping dirt, dust, moisture, and other contaminants at bay. Typically made from durable materials such as rubber or synthetic compounds, these seals are engineered to withstand high temperatures and pressures, which can occur during operation.

Oil seals are typically made of rubber or synthetic materials that are resistant to oil, heat, and pressure. They are designed to withstand the harsh conditions within an engine or machinery, such as high temperatures and varying levels of pressure. The seal is usually placed in a housing or a groove in order to effectively seal the gap between two moving parts.

In various mechanical and industrial applications, seals play a crucial role in ensuring the longevity and efficiency of equipment. Among the many types of seals available, dust seals and oil seals are two predominant types that serve critical functions. While they may appear similar at first glance, their purposes, designs, and applications differ significantly. This article aims to explore these differences, helping you understand when and why to use each type.
