They may also need to be able to resist changes in media and high pressure. In these situations, a high-quality FFKM seal … [Read more...] about High-tech FFKM seal compounds from COG
How can exclusion seals extend hydraulic motor life?
Few people think of the motor’s exclusion seals as key components in a piece of equipment, but these unsung heroes can make all the difference, particularly in harsh environments. When a motor’s pressure seal is compromised, the machine starts leaking oil into the environment, which immediately impacts your bottom line. Lost productivity and … [Read more...] about How can exclusion seals extend hydraulic motor life?

Freudenberg experts weigh in on the future of mobile machinery sealing
If you evaluate seals by cost, they are C-parts. But if you look at the role sealing plays in machine reliability, seals quickly turn into A-parts. And as requirements and environments progress, sealing designs and technologies must as well. Given the latest trends, sealing of the future has the potential to dramatically improve the overall … [Read more...] about Freudenberg experts weigh in on the future of mobile machinery sealing
Why do seals fail?
It’s a fact of life that regardless of how well a hydraulic seal is engineered or how durable the compound, all hydraulic seals will fail at some point. Seals are by nature much softer and less durable than the metal components that they contact. Kenneth James, Mechanical Engineer at MFP Engineering reminds all design engineers that a seal can … [Read more...] about Why do seals fail?
