Precision Needle Roller Bearings for Industrial
The ZIBOO IKO NA4915 needle roller bearings measure 75x105x30mm and suit machinery requiring compact radial support. Engineers and maintenance teams use them in gearboxes, pumps and automated equipment where space is limited. The new condition ensures full service life from installation.
Consistent Load Handling Across Extended Duty Cycles
Needle rollers distribute force over a long contact area, so the bearing resists brinelling during continuous rotation. Heat buildup remains moderate because the thin rollers reduce internal friction compared with wider rolling elements. The design maintains radial stiffness without the axial growth seen in some ball-bearing alternatives. Builders needing angular-contact capacity or integrated seals should select a different bearing type.

Questions about this item
How much heat does the IKO NA4915 generate under continuous load?
Needle roller bearings do not produce measurable heat themselves; temperature rise depends on the surrounding assembly, lubrication and shaft speed.
What shaft diameter must I already have for the 75 mm bore to fit?
The bearing requires a 75 mm shaft; verify your shaft tolerance matches the bearing's internal diameter before installation.
