SKF Needle Bushings, HK 3026 30x37x26

Type HK needle bushings are needle bearings with a thin-walled outer ring made through a chipless manufacturing process. Their key features include a very low cross-section height and high load capacity. They are primarily used where the housing bores cannot be designed as raceways for needle cages, and where space-saving and cost-effective bearings are desired. The needle bushings are pressed into the housing bore and fit securely. This allows for simple and cost-effective manufacturing of the housing bores when no shoulders or retaining rings are needed for axial retention. The outer ring made of hardened steel sheet and the cage-guided needle cage form a self-retaining unit.
