Ball bearing with additional O-ring -MB DEVELOPMENTS- Rear wheel Lambretta Series 1-3 - 2nd oversize 52.08 - 52.10 mm

MB Race-Tour rear wheel bearing in the first oversize (52.08–52.10 mm), suitable for all Lambretta Series 1, 2, and 3 models. But only if the bearing seat no longer matches the original dimensions. 

A high-quality bearing for stock and tuned scooters.

It now features improvements not found in the standard bearing: 

1) It features an additional, large O-ring that is compressed inside the housing after installation, providing an extra seal.

2) The inner bearing surface is chamfered to facilitate the installation of the shaft seal.

The package includes the MBD shaft seal and the special O-ring. Naturally, the bearing now features a recess to accommodate the O-ring.

Like the standard Lambretta shaft seal, this shaft seal measures 32x45x6 mm.

TOP TIP: Apply a small amount of sealant to the O-ring groove and then slide the O-ring over the bearing.
