Réducteurs à vis sans fin avec brides NEMA

The worm gearboxes CM series are built with a completely closed aluminum die-cast housing, and supplied complete with synthetic oil for permanent lubrication. Thanks to its design, conceived for the modularity and the coupling versatility of different types of input flanges, this allows to couple IEC or NEMA motors.
Designed to work with an input speed of 3.000 rpm, they can therefore be used with brushless motors, or stepper, with different flange and shaft dimensions, even without a key.

Caractéristiques

Lubrication

Permanent synthetic oil long-life lubrication (viscosity grade 320) makes it possible to use the CM worm gearmotors in all mounting positions; for this reason they can be installed in any assembly position and do not require maintenance.

Ambient temperature 0 ÷ 40 °C (in the absence of freezing and condensation).
For temperature outside this range please contact our technical dept.
