Mar 1, 2001 · Machines require rotating shaft seals to retain lubricants and prevent foreign particles from entering sealed cavities, which damage machinery and lead to premature failure. Application conditions can vary considerably, and many seal designs have evolved to satisfy these conditions.
SKF industrial shaft seals and accessories are divided into three main groups: Radial shaft seals Axial shaft seals and Wear sleeves. Different seal types within these groups are described with their respective design, materials and applications. Product descriptions are followed by product tables. It should be noted, however, that
Jul 2, 2021 · Rotary shaft seals, also called oil seals or just shaft seals, are used to close and seal the gap between stationary and rotating components. They prevent oil leakage and make sure no contaminants go through the clearance.
Choose from our selection of metal-rubber shaft seals, including rotary shaft seals for grease, shaft-mounted rotary seals, and more. In stock and ready to ship.
Designed to provide an optimized radial load, SKF radial shaft seals are manufactured with a specifically engineered elastomeric compound to offer better oil compatibility. Together, these features provide the improved sealing performance across the entire range.
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. So let's discuss just how each of these is used. Let's start with the simplest first.
Shaft seals, also known as oil seals, are devices that prevent fluids from leaking out of machinery. They're typically made from a rubber or plastic material and are designed to fit around the shaft to create a barrier that keeps oil, grease and other fluids contained.

Parker’s high misalignment rotary shaft Clipper® oil seal profiles are designed to accommodate rotating shaft applications with conditions of shaft to bore misalignment (STBM) and dynamic run out (TIR).
Rotary shaft seals sit between rotating and stationary parts on a shaft to retain oil. They consist of a metal case that fits into a bore housing and a sealing lip made of an elastomer or rubber material which presses against the surface of the shaft to create a seal.
Dec 17, 2020 · Also known as lip seals, shaft seals are mechanical devices that are designed to protect against leakage around a rotating shaft. Machines and industrial equipment, of course, often have one or more rotating shafts. Some of these rotating shafts may contain oil- or lubricant-filled passages.
This guide is designed to help you understand some of the more common and complex Mechanical Shaft Seals technologies on the market. This guide addresses the following topics: Packing. Mechanical Seals. Improving Seal Reliability. Innovative Solutions for Shaft Sealing.
Shaft seals are used in rotary applications, such as a shaft or rotating bore. For more than 40 years ERIKS has supplied oil seals in all possible applications. Rotary shaft seals primary function is to retain system lubricant and exclude external contaminants.
Spring-Loaded Rotary Shaft Seals. Also known as oil seals, use these to retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. A spring secures the lip against the shaft, preventing messy leaks. Press-fit seals into the bore around the shaft.
Mar 7, 2023 · Rotating shaft seals can be found in virtually every facet of daily lives—household appliances, cars and trucks and across industries. Though often treated as a commodity product, their failure can result in costly downtime and lost productivity.
Also known as V-rings and flingers, these seals protect shaft bearings by blocking dust and other contaminants while retaining lubricant. They’re Buna-N for excellent resistance to oil and grease. To install, stretch the seal over your shaft and press it firmly against the face plate.
Sep 27, 2016 · Mechanical seals touch nearly every aspect of industrialized society. Wherever a rotating shaft moves fluid, mechanical seals play a key role in sealing process fluids in, keeping contaminants out, or both. A few basic components and principles in mechanical seal design contribute to a working seal at the interface of the rotating shaft and ...
