Semi-rigid shafts


AR semi-rigid
shafts provide an economical and practical solution to trasnfer the rotary movement between two aligned elements ensuring an optimal and long-lasting efficiency of motion transmission in case of slight misalignments due to construction or installation.
➤ Rigid protection cover made of aluminium.

• Terminals made of stainless steel AISI 303, available models (see section "Accessories"):

- cylindrical solid CL  - cylindrical female CF 
cylindrical male CM          - 2 piece cylindrical male CMB

2 pieces connection bushings with screws to couple gearboxes and shafts.

Support units (with square flange) with o.ring, and ball-bearings.

• Available shafts Ø6, Ø8, Ø10, Ø14, Ø20.
• On request threaded bores or drillbores for screws.
• They can be used severally on screws, female screws, shafts or can be combined with our flexible shafts, and our position indicators type “OP”.
• Particularly the combination with flexible shafts an position indicators offers a simple and complete solution for handling and display of motion

FLEXIBILITY AND BENDING RADIUS


Flexibility and minimum bending radius are important factors especially if the shaft is exposed to severe bending during its use.
It is necessary to make sure that the lowest bending radius applied to the transmission is greater than its minimum radius of curvature. If during use the shaft reaches a bending radius which is below the minimum bending radius, the unit can be crushed, or deformed or excessivley stressed, and thus reduce its strength and / or durability or even cause it to fail. 

Up to this radius it is possible to bend the transmission during operation without damaging or excessive reduction in its lifetime.
