Needle roller andcage assemblies

Product tables …………………………………………………………………………… page 40 âž” fig )anddouble row ( SKF needle roller and cage assemblies areready-to-mount, self-contained, bearing arrangement components. They enable bearing arrangements to be produced whichhave high load carrying capacity and stiff-ness and require a minimum of radial space if the shaft and housing bore can serve asraceways and have the same hardness andsurface finish as bearing rings. If the race-ways are made with increased accuracy, bearing arrangements with high running accuracy can be achieved. SKF needle roller and cage assembliesare available in single row ( âž” fig )designs. They are characterised by •simple and rugged design,•accurate guidance of the rollers in thecage pockets, and •good running properties.The needle rollers are slightly relievedtowards their ends. The modified line con-tact thus achieved between rollers and race-ways means that damaging edge stresses are avoided.
