Explorer angular contact ball bearings feature ground transition raceways/shoulders and modified polyamide/brass cage geometry. They are manufactured from steel with low oxygen content to prevent formation of fatigue-causing oxide inclusions in steel. Upgraded balls offer running accuracy to ISO P6 and heat-treating process stabilizes rings at 150ºC for minimal dimensional changes. Sealed and shielded units contain high temperature urea base grease.
New SKF® Explorer angular contact ball bearings benefit from advanced design, material, and manufacturing-process innovations. SKF Explorer angular contact ball bearings available in both single- and double-row offer a new performance class for users compared with previous designs. The high-performance single-row angular ball bearings as standard can be universally matched in sets for proper clearance or preload to effect proper load sharing, extend service life, enable easier and safer handling and mounting, and reduce inventory.
Applications for angular contact bearings include electric motors, pumps, compressors, air handling equipment, gearboxes, and other equipment utilized in the packaging, food and beverage, medical, general manufacturing, and construction industries.
Among features and benefits for both the single- and double-row bearings are 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. 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.
Upgraded balls offer improved running accuracy to ISO P6 (ABEC 3) as standard and a unique heat-treating process stabilizes rings at 150ºC for minimal dimensional changes (accuracy to ISO P6). Newly developed shields in double-rows can prevent contamination, enhance grease retention, and minimize maintenance. Sealed and shielded bearings contain a high temperature/long life urea base grease compatible with most common industrial greases.
SKF Explorer angular contact ball bearings are available in a wide range of bore sizes and dimensions. Customized bearings can be developed to satisfy particular end-user requirements.
