Needle roller bearing dimensions
This INA RNA4915 needle roller bearing measures 85x105x30mm and is supplied as a single unit in a box. It is manufactured by INA and branded ZIBOO for industrial and automotive maintenance tasks. The bearing provides low-friction rotational support in compact machinery.
Suits precision shaft fits.
Mechanics who need a slim-profile bearing for tight shaft clearances will find this size appropriate. The needle roller design handles moderate radial forces where space is limited. Buyers requiring higher load capacity or integrated seals should consider alternative bearing types.
85x105x30mm envelope
The 85mm inner diameter, 105mm outer diameter and 30mm width define the only envelope that fits the target shaft and housing. Confirm these three dimensions against your assembly drawings before ordering.

Questions about this item
How do I press the RNA4915 bearing onto an 85 mm shaft without damaging the needle rollers?
Apply force only to the inner ring using a sleeve that matches the 85 mm bore; never hammer the outer ring or the cage.
What replacement interval should I plan for the RNA4915 needle rollers under normal electrician-tool duty?
Inspect at each scheduled tool service; replace if rollers show pitting, flat spots or if radial play exceeds the maker’s limit.
Which limit appears first when the RNA4915 runs continuously at high speed?
The 30 mm width constrains lubricant volume, so temperature rise from churning becomes the first sustained-use limit.
