ERMB

Function and application
A toothed belt transfers the rotary movement of a motor to a hollow shaft.
The shafts have ball bearings. The reference position of the hollow shaft can
be scanned with the aid of an inductive proximity switch in the threaded hole 6.
The rotary module type ERMB is intended for turning work loads (e. g. with
grippers). The ERMB is not permitted for application conditions in which vegetable
and water−soluble greases or oils can penetrate into the axis. Vegetable greases or
oils can reduce the capacity of the toothed belt.
Note
The ERMB is not fitted with a brake. When the input torque is not applied,
the rotary module can be moved freely. Generally self−locking of the complete
system can be achieved with motors with integrated holding brake or with high
self−braking torque.
Use the motors specified in the Festo (è catalogue.

You will then be operating two devices which are especially matched to each
other.
When using other motors:

Transport and storage
Take into account the weight of the rotary module. Depending on the design
S
the ERMB can weigh up to 3.3 kg.
Ensure storage conditions as follows:
