HELI-CAL metal slit coupling 

 [Specifications] 
 Open spiral slit in the cylindrical material integral-structured metal coupling with backlash. A and DS models are available with high-strength aluminum alloy. 
 Stainless steel 3000 model (1441 model), the optional use of the environment. Model A and 3000 (1441) model is the one with the maximum angular misalignment of 5 ° 
 Slit model, flexibility is excellent, the DS model to adapt to the high torsional rigidity of the two-slit model. Information about installed on the shaft, the model can be selected for screw 
 Or the use of friction clamp method in two ways. 

 [Details] see below 
 HELI-CAL (Metal slit coupling) 


 HELI-CAL A Model 
 Open a single spiral slit in the material of the cylindrical integral-structured metal coupling with {backlash} zero allowable offset 0.25mm and angle 5 °. 
 High-strength aluminum alloy, the surface treatment of aluminum oxide treatment, good corrosion resistance. Installed on the shaft, you can choose the set screw method (ARM model) 
 And clamp (ACRM models) in two ways. 
 Commonly used torque 0.3Nm ~ 2.3Nm 
 Bores product 2mm ~ 12mm 
 Backlash zero 

 HELI-CAL 3000 (1441) Model 
 Open a single spiral slit in the material of the cylindrical integral-structured metal coupling with {backlash} zero allowable offset 0.25mm and angle 5 °. 
 Made of stainless steel, are not subject to the restrictions of the working atmosphere gas. For installation on the shaft of the way, you can choose screw method (3002M, 1441 models) 
 And clamp (3005M model) in two ways. 
 Commonly used torque 0.4Nm ~ 2.5 Nm 
 Bores product 2mm ~ 12mm 
 Backlash zero 

 HELI-CAL the DS model 
 Open two spiral slit in the material of the cylindrical integral-structured metal coupling with a spiral slit in the HELI-CAL A model, a significant increase in torsional stiffness. Integrated structure, of course, there is no {backlash} zero, can be allowed to offset 0.15mm and angle 3 °. High-strength aluminum alloy, the surface treatment of aluminum oxide treatment, good corrosion resistance. For installed on the shaft, you can select the screw method (DSR model) or the use of friction clamp method (DSCR-type) of these two methods. 
 Commonly used torque 0.8Nm ~ 19.5Nm 
 Bores products 4mm ~ 16mm 
 Backlash zero
