32040X2/DB Tapered Roller Bearing

32040X2/DB is a DB back-to-back matched tapered roller bearing set consisting of two precision matched 32040 bearings. The bearing pair is factory matched to achieve the specified internal clearance and preload condition, providing high rigidity and reliable support for combined radial and axial loads.

The 32040X2/DB matched bearing set features a 200 mm bore diameter and is designed to accommodate axial loads in both directions while maintaining high radial load capacity. The DB arrangement increases the effective distance between load centers, resulting in improved shaft stiffness and enhanced resistance to overturning moments.

Compared with DF face-to-face matched bearing arrangements, the DB back-to-back configuration provides higher moment stiffness and superior resistance to shaft tilting. This makes 32040X2/DB particularly suitable for applications with overhung loads and demanding shaft positioning requirements.

Typical applications include heavy-duty gearboxes, rolling mills, mining machinery, crushers, industrial drive systems and other power transmission equipment operating under high load conditions.
