TYPE 1 BEARINGS

Designed to be fitted to boats up to 45 feet in length the TYPE 1 bearings feature a spherical Ertalyte® knuckle fitted within a precision machined aluminium housing. This results in a bearing that is simple, light and strong.

The spherical knuckle allows the bearing to self-align while the rudderstock rotates within the bearing.
Bearings can be used with both metallic and composite rudderstocks.
Bearings are available in any size for 20mm to 110mm in 10mm increments. Knuckles can be bored any size to suit the rudderstock.
Bearings are available in three housing styles to suit all installation details.
Aluminium bodies are anodised in our in-house anodisation plant to ensure quality and prevent corrosive action.
The bearing is non-watertight and is to be installed with either a full between the upper and lower bearing or half rudder tube between the lower bearing and a seal carrier located partway up the rudder stock above the waterline. See installation for further details.
Type 1 Bearings are BUREAU VERITAS and CE approved.
