The current global electric motor market is valued at more than 100 billion dollars and is slated for continued growth in the decades to come.
It’s estimated that more than 30 million electric motors are produced every year. The increased development of robotics and automation in many industrial processes as well as demand for numerous consumer applications continues to fuel growth.
The recent push and increased adoption of electric vehicles, including everything

GFS Wiper Seals (also known as Scrapers or Excluders) operate to exclude contaminants from entering the sealing system. These contaminants include dirt, mud, dust and moisture. The presence of these contaminants will have a negative impact on the performance of the equipment, and the life of the seals. Poor Wiper Seal performance is amongst the most common causes of premature sealing system failure. Wiper seals function in both a static environment when the equipment is stationary, and dynamically

The oil and gas industry poses some of the most challenging seal applications for any seal designer. This is largely due to the varying chemical compatibility of fluids, and extremely high temperatures. The fluids often contain solids, which tend to be extremely abrasive. And applications are usually at high rotary speeds with extreme pressures.
This combination creates PV values (pressure x velocity) often reaching the limits of the seal materials. On top of these extremes, as seal designers

A component’s reliability and service life are top priorities for wind turbine manufacturers. This is especially true for main shaft seals, which are exposed to powerful forces. In addition, larger shaft diameters have prompted adoption of new, more stringent operating requirements. Freudenberg Sealing Technologies has succeeded in developing a new seal that reliably prevents leaks from the grease-lubricated main bearings used in conjunction with these shafts while tolerating strong shaft runout.

Sealing large joints or multiple grooves can pose cost and timing issues within product development. Extruded cord is often used to work within the program budgets and time constraints. However, that can create issues with splicing, RTV application, and inventory management.
To address these challenges, Parker has developed a new “Jigsaw” extruded seal design. The differentiating feature of this unique cross-section is the precise interlock when the cut-to-length seal ends are overlapped. When

Machining plastics is as much a skill as it is an art form. It takes understanding that whenever you cut a part, it will probably have some motion or energy still within the material.
This is largely because a lot of parts have more rebound than steel in the cutting process. And while plastics are mostly thermally stable, they’re not dimensionally, thermally stable.
Changes in temperature from the time the part is machined, inventoried, and put into service show that typically parts are

Fastener Seals consist of an inner rubber component used in conjunction with an outer metal washer that supports the sealing function of a fastener such as a screw or bolt. The rubber and metal combination create an ideal fit to eliminate any clearance gaps between the housing components and protects against potential leaks in many static applications.
Fastener seals are intended to take the place of an o-ring in certain assemblies. By using a fastener seal, there is no need to have an

As the operating parameters of industrial technologies and manufacturing processes get more extreme, the need for optimal sealing solutions become that much more important.
Elevated temperatures and pressures, higher speeds, extreme environments, faster gas decompression, and aggressive medias all make sealing more critical. This extends right across static, reciprocating, rotary, and oscillating applications.
This challenge has been met very effectively

What is a Speedi-Sleeve?
A thin-walled sleeve [0,28 mm (0.011 in.)], developed by our friends at SKF, is simply pushed in position over the worn area, fit tightly, providing a counterface surface that is optimized for radial shaft seals and typically harder than that of a new shaft.
There is no shaft disassembly or machining involved and costly downtime is minimized. Since the same sized seal as the original can be used, there is no need to search for other seals, or

For the sealing expert, the world of sealing terminology comes naturally.
But for those who don't live and breathe seals every day, the list of terms can quickly become quite daunting.
