Bearings are made to exceed ISO tolerance specifications.
October 25, 2005 -
Dimensionally interchangeable with standard products, SKF® Explorer bearings are manufactured from low-oxygen steel and feature ground transition raceways/shoulders. Modified polyamide/brass cage geometry lends to speed ratings and acceleration, lower heat generation, and reduced vibration and noise, while heat-treating process minimizes dimensional changes. Products come in multiple roller, ball, and thrust bearing configurations.

SKF® Explorer Bearings Launch New Performance Class
SKF® Explorer bearings introduce a new performance class of rolling bearings benefiting from advanced design, material, and manufacturing-process innovations. This next generation of bearings has been engineered to exceed performance normally expected with bearings designed to ISO tolerance specifications. Depending on bearing type, dramatic improvements in service life, load-carrying capacity, friction, noise and vibration, wear resistance, and speed capabilities can be realized.
Extensive SKF testing has documented that Explorer bearings can last in applications up to 300% longer than standard bearing products.
Types include spherical roller bearings, angular contact ball bearings, cylindrical roller bearings, spherical roller thrust bearings, tapered roller bearings, deep groove ball bearings, and four-point contact ball bearings. All Explorer bearings are dimensionally interchangeable with standard products.
Some design features and benefits include ground transition raceways/shoulders to deliver higher thrust load capability, lower overall contact stresses, and reduced edge stresses for increased power density, load rating, and safety. Modified polyamide/brass cage geometry promotes higher speed ratings and acceleration, lower heat generation, and reduced vibration and noise.
Upgraded balls offer improved running accuracy and a unique heat-treating process minimizes dimensional changes. Their manufacture from steel with low oxygen content using state-of-the-art techniques serves to extend life and reduce fatigue failure by preventing formation of fatigue-causing oxide inclusions in the steel.
Newly developed shields can prevent contamination, enhance grease retention, and minimize maintenance for increased machine uptime.
