Ball bearing with additional O-ring -MB DEVELOPMENTS- Rear wheel Lambretta Series 1-3 - standard size 52.01–52.02 mm

MB Race-Tour rear wheel bearing in standard size (52.01–52.02 mm), suitable for all Lambretta Series 1, 2, and 3 models.

A high-quality bearing for stock and tuned scooters.

It now features improvements not found in the standard bearing: 

1) It includes 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 fitting 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.

The shaft seal has the same dimensions as the standard Lambretta shaft seal: 32x45x6 mm.

If a standard-size bearing fits into the bearing seat of the engine housing, the MB rear wheel bearing is also available in larger sizes. 

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