- LUBRICATION - PAINTING
All, gearboxes and variators are supplied, CHA type excluded, complete with lubricant.
The gearboxes maintenance free are lubricated with synthetic oil the others with mineral oil.
It is very important to verify the mounting position because sometimes adding some oil is
enough, in other case to lubricate bearings with special grease would be necessary. Use only
recommended oils.
Warning in case of heavy work itis better to install, where possible, breather plug.
All the gearboxes and electrical motors are painted Grey RAL 9022 with epoxy resins powder.
Big gearboxes and motors are cast iron made, aluminium all the others.
The radial loads is proportional to the requested torque and inversely proportional to the
transmission member diameter following this formula.

When the radial loads is not applied on the centre line of the shaft it is necessary to use the
following formula.
