Product details
SKF Needle Bushings, HK 0408 4x 8x8
Needle bushings of type HK are needle bearings with a thin-walled outer ring manufactured 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 be designed as raceways for needle cages, and particularly where space-saving and economical bearings are desired. They are pressed into the housing bore and sit firmly. This allows for simple and cost-effective manufacturing of the housing bores when no shoulders or retaining rings are needed for axial fixation. The outer ring made of hardened steel sheet and the cage-guided needle cage form a self-holding unit. Main dimensions: ISO 3245:2007 / DIN 618-1:1993 / DIN 618-2:1993, as far as standardized.
Additional markings:
RS Grinding end seals (NBR) on one side
2RS Steel sheet reinforced contact seals made of acrylonitrile-butadiene rubber (NBR) on both sides
TN Glass fiber reinforced cage made of polyamide 66.
