When to Use a PTFE Rotary Shaft Seal - Advanced EMC

PTFE rotary shaft seals perform extremely well in high-speed applications with shaft surface speeds up to 35 m/s. PTFE also has the lowest coefficient of friction of both polymers and elastomers, making it perfect for seals that must have an extremely low coefficient of friction. This can be a critical factor in high-speed rotary shaft seal

Skf rotary seals -

SKF rotary machined seals further extend the options you can choose from. For highly contaminated environments, you can use the SKF three-barrier solution ( fig. 11 ). The first barrier is the external housing seal, the second barrier is the grease fill in the housing, and the third barrier is the integral bearing seal.

What Are Rotary Shaft Seals? - CinchSeal

Rotary shaft seals prevent leaks by creating a seal around the rotating shaft of screw conveyors, ribbon blenders, mixers, bulk handling equipment and more.
