Industrial Thrust Bearing 51420

The ZIBOO NTN 51420 is a thrust ball bearing built for axial-load applications in industrial machinery. It suits maintenance engineers and equipment assemblers who need a single, boxed unit for shaft diameters of 100 mm and housing bores of 103 mm.

Sustained Axial Load Handling

Under continuous thrust the bearing distributes force across its precision balls and raceways without the overheating common in short-test cycles. The 205 mm outer dimension provides a large contact area that maintains rolling stability during extended duty periods.

Dimensional Fit Limits

The fixed 100x103x205 mm envelope means the bearing only fits shafts and housings machined to those exact tolerances. Installations requiring a different bore, outer diameter or width cannot use this unit without redesigning the mating components.

Questions about this item

How much heat does the NTN 51420 thrust ball bearing generate during continuous operation?

The bearing is a passive mechanical component and produces no measurable heat of its own; any temperature rise comes from the surrounding application.

What shaft and housing dimensions are required to install the NTN 51420 bearing?

The bearing fits a 100 mm shaft and a 103 mm housing bore, matching its 100x103x205 mm specification.

Will the NTN 51420 bearing work with existing 100 mm shafts in older equipment?

Yes, its 100 mm bore matches standard 100 mm shafts, so it can replace worn bearings in legacy assemblies without modification.
