NTN 51148 Thrust Ball Bearing

The ZIBOO NTN 51148 is a thrust ball bearing built to handle axial loads in industrial machinery and heavy equipment. Its construction suits maintenance teams and engineers who need reliable rotational support for shafts and assemblies. The unit arrives new and ready for installation in compatible housings.

Sustained axial load capacity

Under continuous thrust forces the bearing distributes load evenly across its rolling elements to limit localised stress. Heat generation remains controlled during extended runs, helping preserve lubricant life and dimensional stability. The design resists deformation when subjected to steady directional pressure over long periods. Buyers needing radial load capacity or high-speed radial rotation should select a different bearing type.

Questions about this item

How much heat does the NTN 51148 thrust ball bearing generate during continuous all-day operation?

As a passive mechanical component, the NTN 51148 thrust ball bearing generates negligible heat during continuous operation; any temperature rise comes from the application's load and speed, not the bearing itself.

What shaft and housing dimensions must already be in place for the NTN 51148 bearing to install correctly?

The NTN 51148 requires a 240 mm shaft diameter, a 297 mm housing bore, and 243 mm of axial space to seat properly.
