SKF Drawn cup needle roller bearing

SKF needle sleeves, HK 1712, 17x23x12

HK type needle sleeves are needle bearings with a thin-walled outer ring made without cutting. Their key features include a very low cross-section height and high load capacity. They are primarily used where the housing bores cannot serve as raceways for needle cages and where space-saving and economical bearings are desired. They are pressed into the housing bore and fit securely. This allows for simple and cost-effective manufacturing of housing bores when no shoulders or retaining rings are needed for axial positioning. The outer ring is made of hardened steel sheet, and the cage-guided needle cage forms a self-supporting unit. Main dimensions: ISO 3245:2007 / DIN 618-1:1993 / DIN 618-2:1993, as far as standardized.

Suffixes:
