The applications for the 42000Z series bearing:

The 42000Z series bearings are suitable for all types of hull material. This bearing is the perfect solution as top bearing for cruising an cruising/racing yachts as it combines a horizontal roller bearing with a vertical roller bearing and a deck cover. Due to the vertical roller bearing arrangement, the rotation of the rudder shaft is extremely smooth. The bearing is ideal as a deck or cockpit floor bearing as it doesn't extend beyond the deck level, especially when the deck flange is let into the teak deck. In combination with emergency tiller arrangement type 1 a quick and save access to the emergency steering is achieved. The bearing is available in three sizes, so one should take notice of this when designing the rudder stock.
