Transmission steering boxes


Jefa BG12 and BG15 steering gearbox
The Jefa BG12 steering box is used when a steering position is required without the use of a standard pedestal. The mounting is done from the inside of the pedestal. When mounting from the inside isn't possible, one should use the "quick mount" version described below.
The BG12 steering box has a 1:1 gear ratio, when more turns of the wheels are required, one should use the step ratio gearbox BG15 with a reduction of 1,2:1. The BG12 & BG15 are standard equipped with a high efficiency friction brake.
