Engineers, mechanics, and serious DIYers working on motors, gearboxes, automotive drivetrains, and industrial machinery rely on drawn cup needle roller bearings to handle heavy radial loads where space is at a premium. These HK-series bearings are designed for exactly that challenge.\u003c\/p\u003e\n    \u003cp\u003eEach bearing in this range features a thin-walled drawn steel outer cup with a full complement of needle rollers retained inside. Inner diameters (d) span 14–25 mm (0.55–0.98 in), outer diameters (D) span 20–32 mm (0.79–1.26 in), and widths (B) range from 12–22 mm (0.47–0.87 in). Available sizes include HK1412, HK1416, HK1512, HK1516, HK1520, HK2216, HK2220, HK2512, HK2516, HK2518, HK2520, and HK2522.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include replacement bearings for small electric motor end caps, gearbox shaft support in power tools, cam follower applications in automation equipment, and needle bearing replacement in automotive rocker arms — all scenarios where a drawn cup needle roller bearing for tight-clearance shaft support is the correct engineering choice.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e🔩\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits standard HK-series bearing housings.
