ZIBOO IKO NAU4912 Cylindrical Roller Bearing 85x60x25mm

SKU CH-3VW2-PBEEP

Cylindrical roller bearing measuring 85x60x25mm for high-load rotating applications

  • Cylindrical roller design handles high radial loads
  • 85 mm outer diameter fits standard housings
  • 60 mm inner diameter matches common shaft sizes
  • 25 mm width allows compact installation

IKO NAU4912 Cylindrical Roller Bearing

This IKO NAU4912 cylindrical roller bearing is a precision component designed for machinery requiring high radial load capacity within a compact envelope. It suits engineers and maintenance technicians specifying original-equipment replacements for gearboxes, electric motors, or industrial transmissions. The 85 mm outer diameter, 60 mm bore, and 25 mm width define its installation footprint.

Dimensional constraints for shaft and housing fits

The bearing operates within the fixed geometry of an 85 mm outside diameter, 60 mm bore, and 25 mm width, so shaft and housing seats must match these dimensions precisely. Axial displacement is not accommodated by this single-row design, limiting its use to locating positions or paired arrangements where another bearing handles thrust. Lubrication method and speed rating depend on the specific application details not provided here.

Questions about this item

Is the 85×60×25 mm NAU4912 the right cylindrical roller bearing for my shaft and housing dimensions?

The bearing has an 85 mm outer diameter, 60 mm inner diameter and 25 mm width; match those three figures to your shaft and housing tolerances before ordering.

What does the 25 mm width mean for load capacity once the NAU4912 is installed?

The 25 mm width gives a broad roller contact area, so the bearing handles high radial loads while fitting in the standard 85×60 mm envelope.
