Stamped outer ring needle roller bearing

Leveraging its century-old precision manufacturing expertise, SKF specializes in two major series of stamped outer ring needle roller bearings: HK open type and BK sealed type. These products feature a quenched and deep-drawn thin-walled outer ring integrated structure, with a small radial cross-section, excellent radial load capacity and rigidity, and are equipped with sealed versions pre-filled with long-lasting grease. Direct interference fit simplifies the housing machining and assembly process, making them widely applicable to rotating support scenarios with narrow installation spaces, such as automotive components, power tools, automation equipment, hydraulic components, construction machinery, and small gearboxes.
