ZIBOO NTN 51256 Thrust Ball Bearing 280x284x375mm

SKU CH-8SXE-73RKS

A thrust ball bearing measuring 280 by 284 by 375 millimetres for axial load support

  • Thrust ball bearing handles axial loads in one direction
  • NTN 51256 model designed for precision engineering applications
  • 280 mm bore fits shafts of that exact diameter
  • 375 mm outside diameter matches housing specifications

ZIBOO NTN 51256 Thrust Ball Bearing

The ZIBOO NTN 51256 is a thrust ball bearing designed to support axial loads in rotating assemblies. It suits engineers and maintenance technicians who need a replacement component with the exact 280x284x375mm envelope. Buyers who require radial load capacity or a different bore size should select an alternative bearing type.

Thermals noise and power draw in normal use

As a purely mechanical component, the bearing generates no electrical power draw and produces no audible noise on its own. Operating temperature depends entirely on the surrounding machinery, lubrication condition and applied axial load. Proper installation and regular lubrication are essential to maintain low friction and prevent premature wear.

Questions about this item

How is the NTN 51256 thrust ball bearing installed and what step is often missed?

Press the 280 mm bore evenly onto the shaft using a sleeve that contacts only the inner ring. The step often missed is keeping the 375 mm outer ring free so it can float axially.

What maintenance or replacement will the NTN 51256 thrust ball bearing need later?

Re-grease at intervals suited to the load and speed. Replace the unit if axial play exceeds the application limit or if the 284 mm raceway surfaces show pitting or wear.
