MECHANICAL OR ELECTROMAGNETIC COUPLINGS

MECHANICAL COUPLINGS SERIES 30100 - 30300 - 30500
They are unidirectional and bidirectional.
When coupling with hydraulic pumps we recommend to engage and disengage the pump when the directional valve is in exhaust position at a speed not over 1800 R.P.M.
In the reversible position the max engagement and disengagement speed is 1000 R.P.M.

LUBRICATION
Oil type SAE 90.
Change oil every 12 months.
Max working temperature + 80°C
Mm working temperature —10°C

ELECTROMAGNETIC COUPLINGS SERIES 30900
Running-in is required to obtain the desired rated torque values of electromagnetic couplings. Running-in is required to obtain the desired rated torque values of electromagnetic couplings. Running-in is carried out by engaging and disengaging clutch at high speed several times with the pump in exhaust position.
During assembly, make sure that there are no oil or grease traces on pulley surfaces whith must be completely clean.
When assembling electric clutches with front driving flange, check for proper coupling alignment, but do not exceed rated torque because this would cause slippage of contact surface. This stage must not last more than 5 seconds since coils could burn.
