Cone-and-Cup Separable Construction
The 9285 (cone) and 9220 (cup) are manufactured as a matched set but can be mounted and dismounted independently. This is a practical advantage in gearbox and axle servicing: the cup can be pressed into the housing while the cone assembly remains on the shaft, or one component can be replaced if the other is still serviceable.
Combined Radial and Unidirectional Axial Capacity
Tapered roller geometry allows the bearing to support radial loads and axial loads in one direction simultaneously. In a typical shaft arrangement, two 9285/9220 bearings are mounted in opposition (back-to-back or face-to-face) so that the pair handles axial thrust in both directions. The 271 kN dynamic / 330 kN static ratings place it in a load class suited to gear reducers, axle pinion supports, and heavy industrial drive shafts.
Defined Axial Load Factors for Engineering Verification
The catalog publishes the full set of ISO load factors (e = 0.71, Y₂ = 0.85, K = 0.82). An engineer can calculate the equivalent dynamic bearing load (P = XFᵣ + YFₐ) directly from the application’s radial and axial forces, then verify L₁₀ life against the rated C = 271 kN before specifying the bearing.
