Jefa RP100 rack and pinion steering pedestals

• All pedestal parts are machined from seawater resistant solid Aluminium 6082. As this material is also used for rudder shafts, it will not corrode, even when it's exposed by a surface damage. No casted aluminium parts are used in this pedestal.
• The robust powder coated aluminium base has no mounting holes for pedestal bolts as these are integrated in the pedestal deck flange. This avoids multiple weak points for damage with the accompanying corrosion and possible leaking.
• The input socket has no exterior mounting bolts for a stylish look and avoiding multiple potential corrosion and damage points.
• The robust guardrail is mounted directly to the pedestal head avoiding a top plate with mounting bolts with potential corrosion points.
• The compass binnacle is integrated in the pedestal design avoiding a set of mounting bolts with potential corrosion.
• The steering shaft is sealed by the Jefa developed PUR seal. Normal industry seals use steel reinforcement rings in the rubber housing. As the standard industry rubber will start to crack due to the UV in the sunlight, the steel rings will corrode and destroy the seal letting water in the steering shaft bearings with disastrous effects. The PUR seal will guarantee an life long sealing. 

The 100 series pedestal is available as WP100 for wire steering, RP100 for rack and pinion steering and TS100 for transmission steering. All pedestals are CE approved.

• The input pinion has no exterior mounting bolts for a stylish look and less chance of damage and corrosion. The input assembly can be easy removed from the inside of the pedestal.
• The nickel aluminium bronze gearwheel is not casted but made from solid extruded nickel aluminium bronze, making it extremely strong and homogeneous and free from any porosity.
• The gearwheel is bolted to the vertical driving shaft with 4 off M12 bolts allowing the gearwheel to be easy removable for service, inspection and if necessary future replacement.
• The vertical driving shaft is made of high strength aluminium (proof stress of 280 N/mm² compared to 200 N/mm² for stainless steel) with a large outside diameter of 70 mm and a wall thickness of 5 mm making it indestructible and enormously stiff, so the gears will never run out of mesh.
• The vertical driving shaft bottom bearing is a 70 mm Jefa rudder bearing guarantying a strong and non-corrosive solution.
• The output lever isn't welded to the vertical driving shaft but secured with a double key. This provides the most flexible solution as the position of the lever depends on the variable deck thickness and can be adjusted during the installation. The distance between the bottom of the deck flange and the top of the lever is adjustable from 41 to 120 mm. Another advantage of this solution is the fact that the steering geometry can be swapped from starboard geometry (standard) to port geometry during the installation.
• The draglink between the pedestal and the rudder is made of anodised high strength aluminium, which provides a stronger and lighter solution than a stainless steel variant.
• The 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.)
