The design of the RAO series gearbox utilizes a fully machined and bored case, enabling totally universal assembly.

The compact design combined with the use of high quality materials makes this series highly suitable for arounds applications.

These groups are manufactured with 2 reductions( a set of bevel gears and a set of parallel gears) and with 3 reductions, with a set of ground helical-toothed parallel gears placed before the bevel gear.

For size 70-90-110-130 the structure in the same as corresponding RAP; the only variation is the assembly of the front bevel gear set.

the units with 3 reduction stages have the motor directly coupling.
