The Jefa 100 series aluminium draglink
With the 100 series draglink Jefa Steering introduces a new style of draglink design. The use of high strength aluminium AlMgSi1 creates a lighter and stronger solution over the common stainless steel solutions (proof stress of 280 N/mm compared to 200 N/mm for stainless steel).
The fully articulated rose joints on the draglink aren't industry joints, but a special design by Jefa Steering and made from high strength anodised aluminium with an easy removable delrin ball inside. This solution finally solves the electrically disconnection of the rudder from the rest of the steering system and boat. (See our electrolysis page for further information.)
Due to the long threaded part of the rose joint a total adjustment of 110 mm is created. This high adjustment eliminates the necessity to weld the draglink to length, one merely has to choose the correct draglink for the length required.
The delrin ball can easily be removed by rotating it 90 and pulling it out of the housing. As a rose joint is one of the wearing parts of a rack and pinion system, this solution provides a simple and cheap service exchange in the future. Conventional rose joints need to be completely exchanged when worn.
The Jefa rose joints standard have a 16 mm hole, but they are also available in imperial sizes for replacement on other steering systems.
The Jefa draglinks up until 600 mm centres have 25 mm thick wall tubing, from 600 mm to 1400 mm centres 30 mm thick wall tubing is used. Both tubes have an inside diameter of 18 mm.
