Product Introduction

The 807046/807010 is a heavy-duty imperial tapered roller bearing sharing the same outer cup profile as the 807010 series (104.775 mm OD, 36.513 mm width) but equipped with a 50.8 mm (exactly 2.000 inch) inner bore cone (807046). This structural configuration provides thicker inner ring walls for extra strength under severe shaft deflection. Crafted from high-purity GCr15 chrome steel with precision-ground raceways, this bearing effortlessly handles extreme dynamic radial loads and unidirectional thrust. It is a critical replacement item for heavy vehicle fleet maintenance and industrial drive repair.

Applications

Commercial truck drive axles, rear differentials, and transmission shafts.
Heavy agricultural harvesters, tractors, and tillage equipment.
Mining equipment, industrial crushers, and reduction gear units.

FAQ

Q: What is the main difference between 807046/807010 and 807049/807010?
A: Both use the same outer cup (807010, 104.775mm OD), but the 807046 has a 50.8mm (2.000 in) bore, while the 807049 has a 53.975mm (2.125 in) bore.
Q: Can this model handle heavy reversing impact loads?
A: Yes, its case-hardened alloy structure is specifically built to withstand high torque spikes and shock loads in drive systems.
