FAQ

What does the 'S11' suffix in the part number 23240CE4S11 signify?

The 'S11' suffix indicates a special heat treatment applied to the bearing rings. This stabilization process allows the bearing to operate reliably at temperatures up to 200 degrees Celsius without significant dimensional changes.

Is this bearing suitable for applications with high misalignment?

Yes, absolutely. As a spherical roller bearing, its internal design with two rows of symmetrical rollers and a common sphered raceway in the outer ring allows it to accommodate both static and dynamic misalignment.

What type of lubrication is recommended for this bearing, especially at higher operating temperatures?

For high-temperature operation near its 200 deg C limit, a high-quality synthetic oil or grease with a high viscosity index and excellent thermal stability is required. Always consult the machinery manufacturer's guide and NSK's lubrication specifications for the specific application to ensure optimal performance and service life.
