Engineers, machinists, and serious DIYers working on motors, gearboxes, automotive drivetrains, and industrial machinery need a bearing that fits where others won't. The HK series drawn cup needle roller bearings are purpose-built for exactly these demanding, space-constrained applications.\u003c\/p\u003e\n    \u003cp\u003eEach bearing in this series features a thin-walled drawn steel outer cup with a full complement of needle rollers retained inside, delivering an exceptional load-to-size ratio. Inner diameters range from 8 mm to 12 mm (approx. 0.31\"–0.47\"), outer diameters from 12 mm to 18 mm (approx. 0.47\"–0.71\"), and thicknesses from 10 mm to 15 mm (approx. 0.39\"–0.59\"). Available sizes include HK0810, HK1010, HK1012, HK1015, and HK1212.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include replacement bearings for small electric motor shafts, needle roller bearings for gearbox countershafts, and compact drawn cup bearings for pneumatic tool internals — all scenarios where radial space is at a premium and reliable performance is non-negotiable.\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 housing bores.
