Radial shaft seals are used between rotating and stationary machine components or between two components in relative motion and consist of two main parts:A cylindrical outer covering of sheet steel (case) or an elastomer that has the requisite interference fit to seal statically against the housing bore.
Mechanical Shaft Seals. The term Shaft Seals is used often and often misused. Technically anything that is sealing a shaft, be it an O-ring, a lip seal, braided packing, or a mechanical face seal can all be called a shaft seal.
Dec 17, 2020 · Shaft seals are a common component in machines and industrial equipment. Like all types of seals, they are designed to prevent substances — typically oil or other fluids — from leaking. A shaft seal will create a secure mating surface … Read More
Rotary shaft seals provide sealing and wiping functionality for rotating and swiveling movements under low pressure and high velocity. They perform two essential functions. The primary function is to retain the bearing or system lubricant in the system to avoid leakage. The secondary function of a rotary shaft seal is to preclude any contamination of the system by external particles or other ...
This article will explain what a mechanical seal is and the key design features that make them work. Basics of fluid pump sealing. A mechanical seal is simply a method of containing fluid within a vessel (typically pumps, mixers, etc.) where a rotating shaft passes through a stationary housing or occasionally, where the housing rotates around the shaft.
Choosing the Right Shaft Seal. When selecting a shaft seal, consider the following factors: Material: Shaft seals are available in a range of materials, including rubber, plastic and metal. Consider the operating environment, fluid compatibility and temperature range when selecting the right material for your application.
Jul 2, 2021 · Table of contents. Shaft seal design; Shaft seal types; Materials; Selection criteria; Shaft seal design. In Figure 2 shows the basic design of a shaft seal differs greatly from regular o-rings.It consists of two parts: a metal ring (Figure 2 labeled B) on the inside that provides stability and strength and the second, a sealing lip (Figure 2 labeled E), which creates a seal against the shaft.

Radial shaft seal of Romo washing machine pump. Radial shaft seals, also known as lip seals, are used to seal rotary elements, such as a shaft or rotating bore.Common examples include strut seals, hydraulic pump seals, axle seals, power steering seals, and valve stem seals. Early radial shaft seals utilized rawhide as the sealing element, and many present-day elastomeric seal companies were ...
Rotary Profiles. Rotary shaft seals are available in many variations of profile (styles), the most common being the TC style. Most profiles feature a sealing lip pre-energised by a helical garter spring and all are available with or without a secondary non-spring loaded dust lip.
