>Product Features and Applications

It is a fully integrated metal coupling with two spiral slits on a cylindrical material, which significantly increases the torsional stiffness compared to the HELI-CAL A model with one spiral slit. As it is an integrated structure, there is no zero backlash, and an eccentricity of 0.15mm and a deviation angle of 3 ° are allowed. High strength aluminum alloy is used, and the surface treatment is aluminum oxidation treatment, which has good corrosion resistance. Regarding the installation method on the shaft, two options are available: the positioning screw method (DSR model) or the friction based clamping plate method (DSCR model).

Common torque	0.8Nm~19.5Nm
Finished products with hole processing	4mm~16mm
backlash	zero
