NTN 51220 Thrust Ball Bearing

This ZIBOO thrust ball bearing carries model number NTN 51220 and is supplied as a single unit in a box. It is intended for technicians and engineers who need a replacement or service part for axial-load applications. The red finish provides visual identification during assembly or inspection. Buyers requiring radial-load bearings or different bore dimensions will need an alternative part.

Thermals noise and power draw

As a purely mechanical component the bearing generates no electrical noise and draws no power during operation. Heat arises only from friction under load and speed conditions determined by the host machine. Lubrication quality and alignment dictate the thermal behaviour in normal use. No active cooling or power supply is required for the bearing itself.

Build fit and clearances

The bearing measures 100 by 103 by 150 millimetres and must match the shaft and housing tolerances specified for the NTN 51220 designation. Correct fit frees the assembly from excessive axial play and prevents premature wear. Installers should verify that the surrounding structure accommodates these dimensions without interference. Applications needing a different envelope or load rating cannot use this unit.

Questions about this item

How do I press the NTN 51220 thrust ball bearing onto a 100 mm shaft without damaging the 103 mm inner race?

Use a sleeve that contacts only the inner ring face, press slowly with a hydraulic press or arbor press, and stop when the inner ring seats squarely against the shaft shoulder.

When should I plan to replace the NTN 51220 thrust ball bearing in continuous service?

Replace at the first sign of axial play, rumble, or overheating; the three-year parts coverage period is a practical benchmark for scheduled inspection.

What operating limit appears first when the NTN 51220 thrust ball bearing runs under sustained axial load?

Temperature rise in the ball-race contact zone is the first limit; if the housing feels hot to the touch, reduce load or improve lubrication immediately.
