5.3 - Painting
5.4 - Protections and packing
Overhanging free shaft ends and hollow shafts are treated with protective anti-rust long life oil and
protected with a plastic (polyethyl ene) cap (for A, E, G and H series only up to D
48 mm for overhanging
shafts, D
110 mm for hollow shafts). All internal parts are protected with protective anti-rust oil.
Unless otherwise agreed in the order, products are adequately packed as follows: on pallets, protected
with a polyethylene film, wound with adhesive tape and strap (bigger sizes); in carton pallets, wound
with adhesive tape and strap (smaller sizes); in carton boxes wound with tape (for small dimensions and
quantities). If necessary, motors are conveniently separated by means of anti-shock foam cells or of filling
cardboard.
Generally the packing is suitable for the normal road/rail transport. For sea transport it is necessary to
foresee a special packing, when ordering.
Do not stock packed products on top of each other.
In order not to affect the protection coat of external paint, avoid damages to it both from a mechanical (ex.
scratch), chemical (ex. aggressive acids) a thermal point of view (ex. sparks).
For typology, specifications, resistance to paint chemical agents, see Tab. 5.3.1.

Before adding further coats of paint, properly protect the seal rings and carefully degrease and sand the
gear reducer surfaces (as alternative to sandblasting it is possible to apply a water soluble primer coat).
In the event of overcoating, use
only conductive paint with surface resistivity values
< 10
