LW170-LW190
The latter is identified by a coded eight digit number,
allowing a complete description of the item.
Example:
I / a b c d e / f g
I - Standard index digit
It is always represented by the digit 1. This number
indicates that the item can be fabricated in a number
of versions differing for material and coating.
a - b - c - d - e - Standard base digits
It is a number always composed of five digits
identifying dimensional specifications of the item.
f - Material index digit
This digit indicates the material used for a defined
item. Its meaning is indicated in the table that follows.
g - Coating index digit
It indicates the coating applied to a defined item.
Note
- For current service use, the following
equivalences can be considered to be valid:
kg = daN; kg/cm
2
= bar; kgm = daNm.
Note
- In case, in the different sections, the tightening
torque is not listed, refer to the table “TIGHTE-
NING TORQUES”, only after identifying exactly the
component.
UNITS OF MEASURE
Units of measure used in this manual are those
adopted by the International System which replace
the units previously used by the M.K.S. system.
Force
:
decanewton (daN) replaces kilogram
(kg)
Pressure
:
bar, replaces kg/cm

Torque
:
decanewton x meter (daNm) replaces
kgm
