Needle Roller Bearing 100x120x35mm
The NTN RNA4917R is a needle roller bearing with a 100 mm bore, 120 mm outer diameter and 35 mm width. It suits maintenance engineers and electricians who need a compact rolling element for radial load support in tight housings. The unit is supplied new in a single box from ZIBOO.
Upgrade from worn plain bushes
This bearing replaces worn plain bushes or failed roller units in motor shafts, gearboxes and linear guides. The jump is worth it when existing clearance allows the 100x120x35 mm envelope and the application demands lower friction and higher load capacity than a sleeve can deliver.
Sustained load behaviour
Under continuous rotation the needle rollers distribute stress across a long contact line, limiting peak pressure and heat buildup. The steel cage retains roller alignment at constant speed, while the red finish aids visual inspection for lubricant condition during scheduled downtime.

Questions about this item
What shaft and housing diameters does the 100x120x35mm RNA4917R bearing fit?
The RNA4917R is a needle roller bearing with a 100 mm bore, 120 mm outside diameter and 35 mm width, so it mounts on a 100 mm shaft inside a 120 mm housing bore.
How do I press the RNA4917R onto the shaft without damaging the needle rollers?
Use a sleeve that contacts only the inner ring face, apply even pressure, and never hammer directly on the outer ring or the red finish — misalignment during press-fit is the common error.
When should I plan to replace the RNA4917R bearing in service?
NTN rates the parts coverage at three years; inspect for noise, heat or radial play at that interval and replace if any wear exceeds the original 35 mm width tolerance.
