Metal-cased single fluoropolymer lip rotary shaft seal

MCB10


Metal-cased single fluoropolymer lip rotary shaft seal

This high-performance seal design incorporates a formed seal lip, mechanically locked into a metal body.  This design creates very low parasitic friction under load and adds much lower heat generation than most seal designs.  This allows the seal to be used successful at higher peripheral speeds, where heat generation is the primary mode of failure for most seals.  The seal is resistant to a very wide range of chemicals allowing it to be used where elastomeric seals cannot be.  Selection of the correct lip and body material will allow use in food and pharmaceutical applications requiring FDA compliance.
