Race-Tec is able to offer a bespoke solution for the more demanding applications where catalogue seals restrict your design. In most circumstances catalogue seals have been designed to suit a wide range of applications resulting in a product that is larger, heavier, and has higher frictional losses preventing you from optimising your products performance and/or size. Catalogue elastomer seals are typically produced using Fluorocarbon (FKM), Nitrile (NBR), Hydrogenation Nitrile (HNBR) each compound has varying performance limits in terms of temperature, surface speeds and fluid compatibility. Elastomer seals typically run with higher friction resulting in increased temperature, higher shaft wear and subsequent oil degradation.
