Breganze Laverda Lower Steering Head Bearing.

Zane Laverda Upper and Lower Steering Head Bearings

This bearing is also fitted to some Laverda SFC750 and RGS models in the upper position in place of the Caged Ball Bearing 22104251 used on previous models. 

You may also require the 2 x Washer under the Bearing in the frame, the Lower Washer on the triple clamp, and the Upper Bearing Cover

Taper roller bearings have tapered inner and outer ring raceways between which tapered rollers are arranged. The projection lines of all the tapered surfaces meet at a common point on the bearing axis. This design makes taper roller bearings particularly suitable for the accommodation of combined (radial and axial) loads.

Taper roller bearings are generally separable, i.e. the cone, consisting of the inner ring with roller and cage assembly, can be mounted separately from the cup (outer ring).

SKF taper roller bearings have the logarithmic contact profile that provides optimum stress distribution over the roller/raceway contacts. The special design of the sliding surfaces of the guide flange and large roller ends considerably promote lubricant film formation in the roller end/flange contacts. The resulting benefits include increased operational reliability and reduced sensitivity to misalignment.
