Product Introduction

The 806649/806610 is a versatile inch-series single-row tapered roller bearing engineered for space-constrained applications requiring reliable radial and axial load capacity. Featuring a 55.975 mm (2.2037 in) inner bore, 88.9 mm (3.500 in) outer diameter, and a slim 19.05 mm (0.750 in) width, this set (Cone: 806649, Cup: 806610) delivers a highly efficient strength-to-weight ratio. Manufactured from vacuum-degassed GCr15 chrome steel, it features super-finished raceways that minimize operational friction, reduce operating heat, and extend lubrication life in automotive and general machinery drives.

Applications

Automotive wheel hubs, light commercial vehicle axles, and differentials.
Agricultural machinery drive shafts and implement wheels.
Electric motors, pumps, gear reducers, and conveyer assemblies.
