SKF has extended the growing family of the SKF Explorer performance class bearings product line to encompass the range of newly upgraded self-aligning roller bearings (spherical roller bearings, CARB toroidal roller bearings, and spherical roller thrust bearings). The bearings also benefit from innovative steel processing technology offering higher performance.

The upgraded steel now used for SKF Explorer self-aligning bearings strikes a balance between hardness and toughness to significantly improve wear resistance.  This enables the bearings to run longer, particularly under difficult operating conditions.  Compared with previous versions, the upgraded Explorer bearings can provide up to twice the service life under harsh conditions where poor lubrication or high contamination levels exist.

All SKF Explorer bearings feature optimized internal geometry to reduce friction, wear, and heat generation and withstand heavier axial and/or radial loads. The rolling elements, which are manufactured to close tolerances, deliver suitable load distribution and run more smoothly with less vibration.  Enhanced cages improve guidance of the rolling elements and maximize the effects of the lubricant to help reduce operating temperatures and extend lubricant life.

Among other features, SKF Explorer bearings incorporate an advanced surface finish to reduce friction and enhance formation of a hydrodynamic film, which promotes effective lubricant performance and reduces heat generation and wear.  A unique heat treatment process reinforces bearing hardness, toughness, and dimensional stability.
