14. Magnetic bridges and metrical scale 
Magnetic bridges are designed for fixing the guides (rigid, flexible, or orbital) to 
ferromagnetic materials. The basic version of the magnetic bridge consists of 
an aluminum body, two magnetic blocks with permanent magnets, and levers for 
fixing to the surface (when in position ‘1’). Thanks to its modular structure, the bridge 
can be easily extended to a version with the fixing mechanism using two M6x20 
screws.  
The fixing range is 58 mm, while using the distance block further extends the range 
by 40 mm. 
The maximum holding force of one magnetic bridge is 1500 N. 
 
 
 
 
 
 
The fixing mechanism is designed for moving the magnetic/screw feet bridges 
radially inside the pipe for mounting or dismounting. Use 5 mm hex wrench to rotate 
the M12x3 feed screw which will move the nut along the pins to the distance of 0–58 
mm. Fasten the mechanism to the magnetic bridge using two M6x20 screws to 
enable adjustment and clamping onto the pipe.
