Low-friction seal reduces CO2

A new range of low friction seals manufactured by SKF can lower CO2 emissions and improve fuel economy. Designed to fit on rotating engine and transmission shafts, the new seals can reduce levels of friction by up to 55%, compared with conventional shaft seals.

The devices feature a low friction elastomer lip design based on the wafer technology used for PTFE shaft seals. They also use a specially formulated FKM material with improved compression set and relaxation properties to compensate for the lack of a spring, normally found in shaft seals. The result is a seal design that provides extremely low friction, outstanding sealing security and long service life. The SKF Low Friction Seal ensures robust sealing and high durability, even at high speed. The seals are also designed to provide improved capability on eccentricity and dynamic run-out compared with PTFE seals, as well as good dry-running ability. According to SKF, they provide minimal shaft wear and have excellent dirt exclusion. The SKF Low Friction Seal is also simple to install because no additional sealants or lubricants are necessary.
