Windpower Engineering highlights “The big impacts of small components”

General, Markets, Renewable Energy, Specialty Sealing Products, Wind Energy,

No component should be overlooked in the quest to increase energy captured by wind turbines. For example, if the seal for a blade pitch bearing—which many consider a commodity—is unreliable, designed improperly, or made with poor material, it will leak grease and eventually prevent the blades from pitching. The whole turbine will under-perform. Hence, small components can have a big impact when not properly designed or tested.

Simrit Advances Piston Sealing Systems to Reduce Friction and Energy Consumption

General, Markets, Press Release,

Simrit, the industrial sealing division of Freudenberg-NOK Sealing Technologies, has developed three new piston seals that reduce friction and lower energy consumption in applications like mechanical transmissions and pneumatic cylinders. The company will showcase its Torque Control Seal (TCS), D-ring with polytetrafluoroethylene (PTFE) enhancement and Friction Piston Seal T-ring (TR) 200 during MDA India (booth #D402 Hall 1) on Dec. 6 to 9 at the Bangalore International Exhibition Centre in India.

“After recognizing the need for advanced piston sealing solutions, we began a comprehensive benchmark of current products which focused on frictional behavior, assembly, shifting time, efficiency, service life and cost,” said Joel Johnson, global vice president of technology, Simrit. “Based on the data gained from this effort, we were able to develop three new seal designs that exceeded current industry offerings.”

With the Low Friction Piston Seal TR 200, Simrit presents an innovative sealing geometry for the smooth operation of pneumatic cylinders with significantly increased efficiency. Reducing friction by up to 50 percent compared to conventional systems, the Low Friction Piston Seal TR 200 shows minimal wear after 15 million cycles. The dynamic sealing function of the Low Friction Piston Seal TR 200 is achieved by a sealing area with a large radius. The required radial force is created by the design interface and eliminates the radial compression of the seal cross section, which minimizes friction and wear while also eliminating stick-slip effects.

Simrit combined the unique advantages of elastomer and PTFE materials to develop two low-energy seals that reduce initial friction, non-linear behavior and hysteresis in piston sealing systems. The TCS is a friction-optimized bonded piston that was specially developed for translatory motion as a transmission shift piston. This seal combines the superior frictional characteristics of PTFE with the rigidity, centering and lip shape (similar to that of a channel gasket) of the bonded transmission piston seal with the metal carrier that was previously used. The TCS is resistant to high temperatures, allows for the mounting of a single part, has an integral piston and offers excellent centering.

The D-ring was developed as a groove seal with PTFE foil enhancement as a friction-optimized piston seal and also employs the dual-layer enhancement procedure. Developed for use in a reciprocating application, the D-ring with PTFE enhancement is a general-purpose piston seal solution that offers very low coefficient of friction and high heat resistance. Offering a range of designs with different diameters, the seal does not twist, is resistant to gap extrusion and offers simple installation.

Simrit Announces New Radial Shaft Seal Material for Industrial Gears

General, Markets, Press Release,

To address the compatibility requirements of increasingly popular synthetic lubricants used in industrial gears, Simrit has created an advanced fluoroelastomer material (75 FKM 260466 ). The new material, a wear-resistant FKM, was developed for use in radial shaft seals that interact with aggressive oils in various industrial gearbox sealing applications. 

FKM material blends are commonly used in applications containing synthetic oils, as they offer superior high-temperature and chemical resistance compared to other material blends. However, when previous blends encounter synthetic oils they can demonstrate wear and material degradation which reduces the service life of the entire application.

“In order to make full use of the advantages of high-performance polyglycol-based lubricants in industrial gears, we had to develop a solution that could withstand the aggressive nature of these oils,” said Joel Johnson, global vice president of technology, Simrit. “Our Simrit material experts developed a tailor-made polymer structure that extended previous FKM material limits, focusing on the wear behavior and tightness of a sealing material.”

Simrit’s Wear-Resistant FKM material provides a high level of wear resistance when in contact with synthetic oils and excellent resistance properties over the service life of radial shaft seals across many temperature and load ranges. Developed and tested according to Six Sigma quality principles, Simrit’s new FKM material has the potential to extend the service life – lifetimes of 20,000 hours or more are now possible – and decrease the down time of industrial gear applications. Finally, due to a new mixing method, the material can be processed in existing injection molding process equipment.

Simrit’s new Wear Resistant FKM material will be on display at MDA India on Dec. 6 to 9 at the Bangalore International Exhibition Centre in India. Visit the Simrit booth (D402) in Hall 1 for additional product information or to speak with a Simrit expert.

Simrit Develops New FKM Compound to Withstand Extreme Temperatures and Fluids in Turbocharger Applications

General, Markets, Press Release,

Simrit, the industrial sealing division of  Freudenberg-NOK Sealing Technologies, has developed an advanced fluoroelastomer material – FKM (80 FKM 233877) – to withstand high temperature coolant and lubricant used in engines of industrial drive technologies. This FKM is the first material that is resistant to coolant reaching temperatures of 180°C, while also withstanding state-of-the-art motor oils with aggressive additives.  

“Increasingly high temperatures and simultaneous contact with coolant and lubricant are the growing demands that have to be met when sealing wet cylinder liners in and around turbochargers,” said Joel Johnson, global vice president of technology, Simrit. “Standard FKM O-rings can only be used in cooling water at temperatures of up to 125°C. Simrit’s Coolant FKM O-rings can be used permanently at temperatures of up to 150°C, as well as for short periods at temperatures reaching 180°C.”

Developed specifically to meet the strict requirements of internal combustion engines, this FKM’s long-term compression set in coolant reaching 150°C is superior and has been successfully tested against a competitive material in a period lasting 1,000 hours. Manufactured entirely without lead, the new O-ring material is also safe for the environment throughout its entire lifecycle, from compounding and processing to the finished product and, ultimately, to safe recycling.

Simrit’s new Coolant FKM O-rings will be on display at MDA India on Dec. 6 to 9 at the Bangalore International Exhibition Centre in India. Visit the Simrit booth (D402) in Hall 1 for additional product information or to speak with a Simrit expert.
