New SKF Explorer angular contact ball bearings benefit from advanced design, material, and manufacturing-process innovations, the company says. SKF Explorer angular contact ball bearings are available in both single- and double-row, and 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.
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. The ball bearings are manufactured from steel with low oxygen content using state-of-the-art techniques, which extends the life and reduces fatigue failure by preventing formation of fatigue-causing oxide inclusions in the steel, the company says.
Upgraded bearings offer improved running accuracy to ISO P6 (ABEC 3) as standard and a unique heat-treating process stabilizes rings at 150° C for minimal dimensional changes (accuracy to ISO P6), the company says. 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.
