Explorer bearings are 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 testing has documented that these bearings can last in applications up to 300 percent 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.
