The new “CoRX” and “Twin-Ax” deep groove ball bearings for passenger car drive shafts from Schaeffler deliver durability even under extreme conditions. They are equipped with a labyrinth sealing system that keeps contamination out of the inside of the bearing. The special feature of this system is a pair of specially formed sealing rings.



Outstanding sealing action with low frictional torque

Unlike the existing “Seal-Slinger+Ax” deep groove ball bearings, the “CoRX” and “Twin-Ax” bearings feature cassette seals. While “CoRX” bearings are equipped with axial and radial seals, “Twin-Ax” bearings feature two axial lips made from corrosion-free stainless steel. The outer sealing ring is water and dust-repellent. Both bearings have a third sealing lip with minimal interference to ensure that the lubricating grease stays inside the bearing, and it also provides improved wear protection. What is more, the frictional torque inside the bearings is minimised thanks to the optimised sealing lip contact, which means they are ideal components for high-speed drive shafts. “CoRX” and “Twin-Ax” bearings are suitable for a wide range of applications: they can be installed as both prop shaft and side shaft bearings and require no additional seals to be fitted.

Customised components from a single source

Schaeffler has been delivering customised solutions for the entire drive train for decades. Deep groove ball bearings are the perfect answer to the need for low frictional torques, outstanding sealing action, and maximum resistance to tilting. This is further exemplified by the already-established “Single Contact” bearing. This bearing runs with particularly low friction thanks to the optimised contact between its inner and outer ring, and is ideal for integration into the drive train as a semi-locating prop shaft or side shaft bearing. An alternative to this is the “2-Point Contact” bearing, which was developed by Schaeffler’s engineers with a view to providing maximum protection against tilting. Schaeffler’s product portfolio also includes the “Seal-Slinger” bearing, which is equipped with two sealing rings and thus delivers significantly better sealing action.
