The CNC process allows Jefa to deliver high quality close tolerance for new systems and precision replacement and service part for existing systems. Jefa's Transmission Steering System "TSS" is mechanical system for any Sailing vessel with high steering loads or a complex path from the steering wheel to the rudder.
Jefa Steering pedestals are finished with electrostatic powder coating for durable glossy finish that will withstand years of exposure in harsh marine environment. Wire Sheave assemblies are available with sheaves machined from delrin or aluminum alloy.
Today Jefa Rudder is steered with the second generation at its helm, by Jan’s daughter Louise. Jefa rudder bearings offer the utmost in feel and durability.
Starting in 2001, Jefa Steering Systems quickly evolved to become a world leader in sailboat steering systems. Chain & Cable steering systems are the traditional favorite of builder and sailors.
All Jefa rudder bearings are produces with precision machined rollers and close tolerances to provide smooth operation under load. The close tolerance allows Jefa to eliminate the roller cage needed with sloppy bearings and keep the design simple for long term reliability.
The final connection to the rudder is with a solid drag link and tiller arm. The "TSS" is similar to the geared Rack & Pinion system, placing the reduction gearbox close the rudder. This gearbox placement allows the torque tubes to run through the boat with same low loads that will be on the steering wheel shaft.
