Three-part BGM precision roller bearing for the main shaft bearing on the control box side of Vespa VNA, VNB, VBB, Super, Sprint, GT, GTR

All 125/150cc Vespa engines with horizontal cylinder (from approx. 1957 onwards), starting with the still direct intake VNA models, have a multi-part main shaft bearing on the control box side. It was not until the late years of the Vespa Sprint models that a modern, closed needle cage with different dimensions was used (B188).

For a long time the old bearing type was only available from Indian production, finally in a completely unacceptable quality. These have a bearing clearance of over 6/10mm. Thus the main shaft has an enormous amount of play and would be noticed negatively by the TÜV at the latest.

The BGM bearings are manufactured by a well-known Italian company and have a closed bearing cage. Thanks to the precise production and the high-quality material, the main and auxiliary shaft are guided safely and permanently.

Thanks to the closed bearing cage, the rollers are inserted here before the bearing ring is installed.

  • One-piece cage
  • Made in Italy
  • Precise dimensional accuracy
  • Highest quality material

Rodamiento
Después de muchos años sin tener un rodamiento decente como recambio, por fin BGM nos trae éste. Llevo años montándolo en los motores Motovespa con cero incidencias.
