Schaeffler deep groove ball bearingsSchaeffler claims its CoRX and Twin-Ax deep groove ball bearings (for passenger car drive shafts) feature two sealing rings that are interconnected, effectively protecting the inside of the bearing from contamination.

The company says the CoRX bearings use axial and radial seals, while the Twin-Ax units feature two axial lips made from stainless steel. Both bearings have a third sealing lip with designed for minimal interference to ensure that the lubricant stays inside the bearing and improved wear protection. The company claims these bearings are suitable for high-speed drive shafts.
