Description

Product description

3D printer Stepper Motor Flexible Coupling Coupler /Shaft Couplings 5 mm*8mm*25 mm (2Pcs)

Our Precision made, High Quality, Aluminium Helical Shaft coupling is commonly used in 3D Printers, CNC machines and other DIY projects to couple Stepper motors and 8MM rods / threaded rods / precision trapezoidal rods. The coupler takes care of small misalignments, deviations and twists in the system. Our coupling comes with 4 grub screws installed. One package consists of 2 couplers. Please note that the bore diameter of this product is 5MM and 8MM. See specifications below for more details.

Specifications:
Material: Aluminium
Bore Diameter d1: 5MM
Bore Diameter d2: 8MM
Length: 25MM
M: M3 Set Screws 4Nos per coupler.
Outer Diameter Od: 19MM
Qty: 2 Flexible couplers per package
Also known as: Beam coupling, helical coupling, Flexible coupling.

Note: A beam coupling, also known as helical coupling, is a flexible coupling for transmitting torque between two shafts while allowing for angular misalignment, parallel offset and even axial motion, of one shaft relative to the other. This design utilizes a single piece of material and becomes flexible by removal of material along a spiral path resulting in a curved flexible beam of helical shape. Since it is made from a single piece of material, the Beam Style coupling does not exhibit the backlash found in some multi-piece couplings. Another advantage of being an all machined coupling is the possibility to incorporate features into the final product while still keep the single piece integrity. Changes to the lead of the helical beam provide changes to misalignment capabilities as well as other performance characteristics such as torque capacity and torsional stiffness. It is even possible to have multiple starts within the same helix.
