Tapered roller bearing SKF 47487/47420 A/Q, Outer diameter: 120 mm | Inner diameter: 69.85 mm | Width: 34.635 mm

Tapered roller bearings have inner and outer rings with tapered raceways and tapered rollers. They are suitable for bearing combined loads, that is, acting simultaneously in radial and axial directions. The projection lines of the raceways converge at a single point on the bearing axis to ensure excellent rotational properties and, consequently, low frictional moments in operation. The axial load carrying capacity of tapered roller bearings increases as the contact angle α increases. The size of this angle, which is usually between 10° and 30°, is related to the calculation factor e: the greater the value of e, the greater the contact angle.
