New cylindrical roller bearings from SKF offer exceptional performance in large, heavy-duty applications

The new SKF bearings are designed for use in the most demanding of applications including wind turbine gearboxes, large slurry pumps, high torque industrial gearboxes and mining and construction equipment. The new 22 and 23 dimension series bearings are available in measurements up to 420mm outside diameter.

The bearings are designed to accommodate higher speeds by delivering significant reductions in friction and heat generated by the bearing. This has been achieved by an optimised internal geometry and SKF’s unique manufacturing and finishing processes. Combined, these improve wear-resistance and increase service life, which is further extended by a 15% higher load carrying capacity when compared to standard cylindrical roller bearings.

The surface finish of the SKF Explorer cylindrical roller bearings also promotes the efficient formation of a lubricant film across all internal load bearing surfaces. This is especially important in applications where equipment frequently starts and stops, and where conventional bearings can be slow to form a lubricant film leading to increased wear.

In addition, the new SKF Explorer bearings with a PEX designation suffix undergo a specialised heat treatment. This makes the bearings more durable and resistant to shock loads by improving the microstructure of the steel. Through improvements to the surface structure and contact properties, they offer higher axial load carrying capacity, reduced frictional moment and reduced risk of roller-flange smearing.

The enhancements to the SKF Explorer cylindrical roller bearings offer improved reliability and increased service life even in the most demanding of applications, resulting in a lower overall cost of ownership.
