NTN 4T-48286/48220 Tapered roller bearings 123.825 × 182.562 × 38.1 mm

Overview

NTN 4T-48286/48220 Tapered Roller Bearing uses tapered rollers and raceways to handle combined radial and axial loads. It is commonly used in wheel hubs, gearboxes, industrial axles, and heavy equipment where shock load capacity and rigidity are required.

The inner ring, outer ring, tapered rollers, and cage are designed so their cone lines converge at a common point. A single-row bearing supports axial load in one direction, while paired mounting supports bidirectional axial load and preload settings.

Selection guidance

Consider load ratio, mounting direction, preload/endplay, lubrication, and the paired bearing arrangement.
