NTN NA4917R Needle Roller Bearing
The ZIBOO NTN NA4917R is a precision needle roller bearing measuring 85x120x100mm. It serves electricians and maintenance technicians who require reliable rotational support in power tool assemblies or test equipment setups. The component arrives new in a single pack box with a red finish.
Replaces worn bearings in electrician tools
This bearing replaces damaged or worn needle roller units in compatible electrician tools and test equipment. The upgrade is worth it when existing bearings show excessive play, noise, or heat during operation. A three-year parts and one-year labor coverage period applies to the component.
Sustained load performance in tool applications
Under continuous operation in power tool environments, the bearing maintains consistent rotational accuracy and load distribution. The needle roller design handles radial forces efficiently during extended use cycles. Heat buildup remains controlled within the 85x120x100mm form factor during prolonged duty.

Questions about this item
What shaft diameter does the 85 mm bore of the NTN NA4917R needle roller bearing fit?
The bearing has an 85 mm inner diameter, so it mounts directly on an 85 mm shaft with the appropriate tolerance for a needle roller bearing of this size.
How do you press the NTN NA4917R bearing into its housing without damaging the rollers?
Apply even pressure to the outer ring only, using a press tool that contacts the 120 mm outer diameter face, and never hammer the inner ring or the red cage.
When should the NTN NA4917R bearing be replaced based on the supplier’s parts coverage?
The supplier lists a 3-year parts period, so plan inspection or replacement around that interval if the bearing shows noise, play or overheating.
