ZIBOO NTN 30217 Tapered Roller Bearing 85x150x24mm electrician tool

NTN 30217 tapered roller bearing

The NTN 30217 is a tapered roller bearing measuring 85x150x24mm and supplied in a red finish. It is sold as a single unit in a box and classified as test equipment for electrician use. The component carries a three-year parts and one-year labor coverage period. Electricians and maintenance technicians use it to support combined radial and axial loads in rotating assemblies.

Replaces worn or damaged tapered roller bearings

This bearing serves as a direct replacement when an existing 30217 unit shows pitting, excessive play or noise. The upgrade is worthwhile when the original bearing has reached the end of its service life or when a scheduled overhaul calls for fresh rolling elements. It is not suited for applications that require a different bore, outside diameter or width than the 85x150x24mm envelope.

Limited to the 30217 dimensional standard

The bearing conforms to the 30217 series geometry, so it only fits housings and shafts machined to those exact dimensions. It cannot accommodate misalignment beyond the design limits of a standard tapered roller bearing. Installations needing higher speed ratings, different load angles or sealed variants fall outside this part's scope.
