Facilitates connection to other guide systems.
Floating Bracket Operating Precautions
Caution
When connecting to a load which has an external guide mechanism, use a discrepancy absorption mechanism.
Mount the external guide mounting brackets and floating brackets in a place where the required degree of freedom for the floating Y and Z axes can be secured.
The thrust transmission area of the floating bracket must be fixed so that it does not partially contact with the body.
∗ Consult with SMC for details of floating Y and Z axes.
Mounting dimension
One set of brackets can be mounted in two directions for
compact combinations.
