IBC tapered roller bearings
The shape of the rolling elements of tapered roller bearings resembles a truncated cone. At the large cone diameter the inner ring has a high, specially shaped flange that must also transfer a proportion of the axial forces. Together with the cage, the retaining flange at the small cone diameter prevents the rollers from falling out. The outer ring has no flange and is therefore easily removable for installation.
IBC tapered roller bearings are designed for high radial and axial loadings in one direction and for medium speeds. They are manufactured in the series 30...A, 31...A, 32...A. If arranged in pairs axial loads in both directions are possible. In a tapered roller bearing the contact angle produces a force acting in the axial direction that must be balanced out by a corresponding counter-force. For that reason a second bearing must be provided for counter-guidance.
Matched bearing sets in X-, O- or tandem arrangements are possible.
