The SKF Explorer performance class of ball bearings is in response to the ever-demanding performance requirements of modern machinery. SKF Explorer ball bearings realized this substantial improvement in performance by optimizing the internal geometry and surface finish of all contact surfaces, redesigning the cage, combining the extremely clean and homogenous steel with a unique heat treatment and improving the quality and consistency of the balls.

SKF Energy Efficient (E2) bearings ukp210d1 are ideal for light-to-normal load applications, where there is a need to improve reliability, decrease lubricant consumption and reduce energy consumption. Ball bearings within this performance class are characterized by a frictional moment in the bearing that is at least 30% lower when compared to a same-sized SKF Explorer bearing. The bearings realized the substantial reduction of the frictional moment by optimizing the internal geometry of the bearing, redesigning the cage and applying a new, low-friction grease.

SKF super-precision bearings are used in high-speed, precision applications like machine tools, centrifuges, and printing presses, where high speeds, running accuracy and long service life are critical operational parameters.
