SKF has extended its explorer range with a four-row cylindrical roller bearing 4rCRB, aimed at demanding applications in long product rolling mills.

It offers up to 50 per cent longer service life than the previous generation 4rCRB, and it helps overcome challenges caused by contamination, high loads, varying speeds and reversing torques.

Explorer bearings feature reduced friction, increased hardness and improved steel quality that gives them the ability to withstand heavier radial, and axial loads and allows them to run longer than standard bearings.

“Our new SKF explorer line is more robust, resulting in higher reliability and increased service life,”said Gustavo  Guerrero, Director of Product Management for CRBs, SKF. “This improves uptime and productivity for customers, which in turn reduces total cost of ownership and raises overall equipment effectiveness.”
