NTN NA6918 R needle roller bearing
The NTN NA6918 R needle roller bearing is a precision component designed for applications requiring high load capacity within a compact radial space. It suits engineers and maintenance technicians who need reliable rolling-element performance in gearboxes, pumps or automotive transmissions.
Dimensions and operating envelope
The bearing measures 90 mm inner diameter, 125 mm outer diameter and 105 mm width, fixing the shaft and housing seats to those exact figures. Radial clearance and speed ratings are bound by the NA6918 series geometry, so the assembly must respect the 90/125/105 mm envelope without additional machining.
Installation guidance
The bearing arrives new in a single box and should be pressed onto the shaft or into the housing using uniform force on the appropriate ring — never hammer directly on the rollers. Misalignment during mounting or contamination from debris are the most common causes of premature noise and reduced service life.
