Jefa Cable Steering

The Jefa Chain and Cable system has many advantages over competing brands in the market. Jefa's quadrants and sheaves are not made from cast-aluminium like most other quadrants available. As most quadrants will also function as rudder stop, quadrants can have very high impact loads. Cast-aluminium is very brittle and could easily break under these circumstances. All Jefa quadrants and sheaves are fabricated from high strength Aluminium 6082. This material is enormously strong, while retaining high ductility (Jefa Marine produces rudder shafts from the same material), resulting in an extremely strong quadrant arrangement. The quadrants always have twin high precision CNC milled tracks with deep groove depths and large guide bend radii ensuring a reliable and long lifetime of the cable. The twin track arrangement offers flexibility while installing and adds the possibility of crossing the cable between the helm station and quadrant instead of crossing the cables inside the pedestal.
