  elasticityCouplingIt is usually cut from metal round rods, and commonly used materials are aluminum alloy, stainless steel, and engineering plastics.Flexible couplingParallel or spiral grooving system is used to adapt to various deviations and transmit torque accurately.Elastic couplings usually have good performance and have a potential for price. In many practical applications of stepping and servo systems, elastic couplings are products.The one-piece design enables the elastic coupling to transmit torque with zero clearance and without maintenance.The elastic coupling mainly has the following two basic series: spiral groove type and parallel groove type.

  Flexible couplingFeatures:

  (1) One-piece metal elastomer;

  (2) Zero backlash, can run synchronously;

  (3) Elastic action compensates radial, angular and axial deviations;

  (4) High torque rigidity and sensitivity;

  (5) The characteristics of clockwise and counterclockwise rotation are exactly the same;

  (6) Maintenance-free, oil and corrosion resistance;

  (7) There are aluminum alloy and stainless steel materials for selection;

  (8) There are two main fixing methods: top wire and clamping.
