NTN NA6917 R Needle Roller Bearing

The ZIBOO NTN NA6917 R is a precision needle roller bearing designed for machinery requiring high load capacity within a compact radial space. It suits maintenance engineers and industrial assemblers who need reliable rolling-element performance in gearboxes, pumps, or automotive transmissions. The bearing arrives new in a single retail box.

Sustained-load behaviour

Under continuous operation the bearing distributes stress across its long cylindrical rollers, reducing peak contact pressure compared with ball alternatives. The 100 mm width provides extended raceway contact that helps maintain film thickness during prolonged duty cycles. Heat generation remains proportional to speed and lubrication quality rather than spiking under steady torque.

Installation notes

The 85 mm bore and 120 mm outside diameter require accurate shaft and housing fits; interference that is too tight will collapse the thin-walled outer ring. Press force must be applied only to the ring being mounted — never transmitted through the rollers. Misalignment exceeding the manufacturer's angular tolerance will cause rapid edge loading and premature wear.

Questions about this item

How much heat does the NA6917 R generate when running continuously under load?

The NTN NA6917 R is a needle roller bearing, not a powered component, so it produces no heat of its own; any temperature rise comes from the application it supports.

What shaft and housing dimensions must I already have for this bearing to install correctly?

It requires a shaft of 85 mm and a housing bore of 120 mm to match the 85x120x100 mm size.

Can the 100 mm wide NA6917 R share a shaft with a narrower bearing I currently use?

Its 100 mm width determines the axial space needed; an adjacent bearing must fit within the remaining shaft length without interference.
