NTN NA4916R Needle Roller Bearing
The ZIBOO NTN NA4916R is a precision needle roller bearing designed for applications requiring high load capacity within a compact radial space. It suits maintenance engineers and technicians replacing worn bearings in automotive, industrial machinery, or power transmission systems where the 80x110x90mm envelope matches the housing bore and shaft dimensions.
Installation and common issues
The bearing installs by press-fitting the outer race into the housing bore and the inner race onto the shaft using appropriate arbor press tooling or a bearing heater to avoid brinelling the rollers. Misalignment during fitting, contamination from debris, or excessive force on the cage are the typical causes of premature noise or failure.
Behaviour under sustained load
Under continuous operation the needle rollers distribute stress across a long contact line, maintaining stiffness and reducing elastic deformation compared with ball types of similar cross-section. The steel cage retains roller guidance at speed, while the red finish on the supplied unit aids visual inspection for lubricant condition or corrosion during scheduled downtime checks.

Questions about this item
How do I verify the NTN NA4916R needle roller bearing is functioning correctly after installation?
After fitting the bearing, rotate the shaft by hand; it should turn smoothly without binding or excessive play, and the 80 mm bore must seat fully on the journal while the 110 mm outer race sits flush in the housing.
What components are included in the box and what must be purchased separately for the NTN NA4916R?
The box contains one NTN NA4916R needle roller bearing measuring 80x110x90 mm; mounting hardware, lubricant, seals and any required tooling are not included and must be sourced separately.
Which NTN NA4916R version should I choose for my application?
The NTN NA4916R is offered in a single 80x110x90 mm size with a red finish; select this version when your design calls for those exact bore, outer diameter and width dimensions.
