HK Drawn Cup Needle Roller Bearings — Sizes & Specifications

The HK series is a drawn cup needle roller bearing: the rollers run in a thin pressed-steel cup that press-fits into the housing, giving the lightest, most economical needle bearing for its bore. The model encodes bore and width — HK1012 is 10 mm bore, 12 mm wide. HK bearings are standard in small gearboxes, starters, pumps and power tools. BPK supplies the HK range listed here, factory-direct from Yandian, Shandong, for importers, distributors and OEM buyers.
