NTN NA4919R Needle Roller Bearing
The ZIBOO NTN NA4919R is a precision needle roller bearing designed for mechanical assemblies that require high load capacity within a compact radial space. It serves technicians and engineers working on automotive, industrial or power-transmission maintenance where reliable rotational performance is essential.
Fits 95 mm shaft and 130 mm housing
This bearing installs directly onto a 95 mm diameter shaft and seats inside a 130 mm bore, occupying 110 mm of axial length. Its needle roller design minimises radial profile, freeing valuable space in gearboxes, pumps or electric motor housings while still supporting heavy combined loads. The red finish aids visual identification during inspection or inventory checks.
Replaces worn NA4919R units in existing equipment
When an original NA4919R bearing shows excess play, noise or heat, this unit restores factory clearance without redesigning the surrounding components. The upgrade is justified when downtime costs exceed the part cost and when the application demands the same 95x130x110 mm envelope. It is not suited for applications requiring integrated seals, alternative cage materials or different radial internal clearances.

Questions about this item
What are the inner and outer diameter limits that define the 95x130 mm NA4919R bearing?
The bearing has a 95 mm inner diameter and a 130 mm outer diameter, giving the radial space the rollers occupy under load.
How much heat does the NA4919R generate when it runs continuously at rated speed?
Heat rise depends on applied load, lubrication and shaft speed; the bearing itself has no built-in cooling and relies on the surrounding housing to dissipate temperature.
Which shaft and housing tolerances must the installer already provide for the 95x130x110 mm NA4919R?
A 95 mm shaft with the correct fit class and a 130 mm housing bore with the matching tolerance are required so the bearing seats without excess play or interference.
