In our recent story, “Basics of static sealing,” Thomas Braun and Christoph Meissner with the Prädifa Technology Div. of Parker Hannifin's Engineered Materials Group discussed the fundamentals of O-rings and back-up rings. And while rubber O-rings are probably the most common type of static seal, they indicated there are numerous other options … [Read more...] about Alternatives to O-rings for static sealing

Reservoir breather adapter kits for oil draining and filling applications
Schroeder Industries introduces a new way to protect oil from airborne contamination while filling and draining it — the Reservoir Breather Adapter Kits. Contamination is the leading cause of premature system failures. While most operations already use an inline or in-tank filtration solution, others want additional protection to extend the … [Read more...] about Reservoir breather adapter kits for oil draining and filling applications
Basics of static sealing
Static sealing elements are used practically everywhere in daily life, although they typically go unseen. And while sealing technology expertise is limited to a relatively small group of specialists, mechanical and fluid-power engineers must be able to apply the fundamentals to ensure successful designs. In a recent webinar, “Sealing … [Read more...] about Basics of static sealing
How does water impact hydraulic fluid?
By Josh Cosford, Contributing Editor Most hydraulic fluid is oil-based, so we cannot forget the adage that oil and water do not mix well. However, when it comes to the hydraulic oil transferring energy around your hydraulic system, much more is at stake. Whether free or in saturation, the potential harm from water is more detrimental than merely … [Read more...] about How does water impact hydraulic fluid?
Nanoscale surface treatments reduce friction on seals
Seal-Glide from Trelleborg Sealing Solutions is a specially formulated surface treatment to improve assembly processes and application performance by virtually eliminating friction and sticking. Surface treatments are extensively used to improve sealing performance and impart additional properties that the base materials do not have. Finishing … [Read more...] about Nanoscale surface treatments reduce friction on seals
Laws are infallible
By Josh Cosford, Contributing Editor Physical laws, unlike governmental laws, are perfect. The heavy hand of the (physical) law keeps our fluid power realm in check, dictating liquids and gases' behaviours at every location. I'd like to say very few alternate engineering fields so heavily rely on these laws and principles as fluid power, but a … [Read more...] about Laws are infallible
Oil sensor offers real-time, 24-hour monitoring oil degradation
The OQS 2 new and improved Oil Quality Sensor puts users in control with real-time, 24/7 monitoring of oil degradation, oil condition and water ingress and is now available for purchase. The sensor is a live, highly flexible and cost effective condition-based monitoring solution, designed to be permanently mounted within any lubrication system … [Read more...] about Oil sensor offers real-time, 24-hour monitoring oil degradation
What are ionic hydraulic fluids?
Hydraulic development engineers and tribology specialists still expend substantial time, effort and resources in the search for an ideal hydraulic fluid. Novel Ionic Liquids may offer the solution. In a presentation at IFK 2020 titled “Basic aspects when using ionic liquids as a hydraulic fluid,” authors Darko Lovrec and Vito Tič of the … [Read more...] about What are ionic hydraulic fluids?
Material simulation, testing improve lifespan of offshore wind turbines
Freudenberg Sealing Technologies has developed an advanced testing procedure and simulation methodology that, in combination with the company’s Ventoguard portfolio of elastomeric materials, offers performance improvements and better longevity in offshore wind energy component applications. The material simulation process helps to identify optimal … [Read more...] about Material simulation, testing improve lifespan of offshore wind turbines
How can you detect leaks in hydraulic systems?
By Josh Cosford, Contributing Editor Clean, dry and cool hydraulic oil should last you an indefinite period. As long as you properly condition your fluid, there is no reason to change it or add more. If you're in a position to add hydraulic fluid to your system, something has gone wrong. Either you've had to replace a worn component, taking with … [Read more...] about How can you detect leaks in hydraulic systems?
