Problem
When building the Seascape 24, the engineers focussed, among other things, on single-handed offshore racers with easy handling. The steering system has double oars, which allow full control even at high speeds. For the steering to work precisely, a reliable connection between the tiller, drive shafts and oars is required. The connecting parts should each allow 3D movement, with minimal friction, a long service life and zero clearance. Spherical bearings were out of the question for the engineers. The problem here: they corrode when in contact with salt water, seize up, increase the load and wear out the connection pins, which leads to more clearance in the system. Furthermore, rust dripping out might permanently stain the white cockpit floor.
Solution
At igus, the engineers found the technically best and most cost-effective solution: igubal spherical bearings from the KARM series. They consist entirely of high-performance plastics, are corrosion-free and ideal for use in wet environments, with salt water, weak acids and bases. The housing is made of a particularly robust long-fibre-reinforced polymer. The spherical ball made of iglidur W300 is characterised by lowest coefficient of friction and an extremely low stick-slip tendency.The bearing works reliably, with very little clearance and without additional lubrication. This can save you time and effort for maintenance.
