To meet the extreme demands of the evolving windpower industry, one company has expanded line of nitrile butadiene rubber (NBR) sealing materials. Simrit’s two NBR developments are part of its Ventoguard line of materials specifically designed to offer grease and ozone resistance, low compression set, and low-temperature capability.
“The windpower industry is growing and evolving at a rapid pace,” says Reddy Tudi, sales director, renewable energy, Simrit. “To meet the needs of this developing industry, Simrit engineers are continually driving the development of materials and seals that will extend the performance of windpower applications.”
Ventoguard 453 and Ventoguard 454 are the next-generation of the company’s line of NBR materials. Primarily used in slewing bearing profile seals in wind turbines, both materials were developed for long-term reliability and superior resistance to environmental and chemical concerns.
Additionally, each material was designed to address a specific windpower-related challenge with the ultimate goal of helping prolong the maintenance cycle of the sealing application. The company says Ventoguard 453 is a premium material that offers excellent cold flexibility, very good compression set and demonstrates superior aging in several greases, including Kluber, Fuchs and Mobil. Simrit’s Ventoguard 454, also a new premium material, provides superior compression set and is optimized for use in Shell Rhodina BBZ greases.
