Jefa Stainless Steering Wheels

Single spoke wheels
The standard Jefa steering wheels are produced in stainless steel 316 and cover a range from 600 mm to 1200 mm overall diameter in steps of 100 mm. The standard wheels up to 1000 mm contain 5 tapered spokes, above 1000 mm diameter the wheels contain 7 tapered spokes. The hub is made in one part and constructed in an ingenious way, so no welding of the spokes is visible on the outside. Jefa steering has chosen to use as standard a thicker diameter rim of 25 mm in stead of the industry standard of 22 mm. The standard wheels are available in a polished version or covered with leather. All standard wheels are CE approved. Please click on the picture for a larger view. Click for larger view

The Jefa tandem wheel disengagement unit
The tandem wheels can be fitted with a unit to prevent the wheel from rotating while under autopilot cruise. This steering wheel disengagement unit is only available for tandem wheels as the wheel hub of these type wheels is big enough to accommodate the mechanism. By rotating the black knob, the wheel is pulled backwards and 5 off pins disengage from a flange which is attached to the steering shaft. The wheel disengagement unit is a part of the steering wheel and not of the steering system. This means it can be fitted on existing steering systems. Please click on the picture for a larger view.
