Parallel-groove flexible couplings usually have 3-5 slots to cope with the problem of low-torque rigidity.The parallel groove type takes into account the shortening of the groove without reducing the ability to withstand deviations.

Parallel-groove flexible couplings usually have 3-5 slots to cope with the problem of low torque rigidity.Parallel grooves take into account that the cutting grooves can be shortened without reducing the ability to withstand deviations. Short cutting grooves can increase the torque rigidity of the coupling and overlap together, enabling it to withstand considerable torque.This performance makes it suitable for light load applications.For example, the connection of a servo motor and a ball screw.However, this kind of performance will increase the bearing load as the slot size increases, but in most cases, it can effectively protect the bearing.Increasing size means increasing the ability to withstand eccentricity.   

      Nowadays, most of the flexible couplings are made of aluminum alloy. Of course, there are also stainless steel flexible couplings.In addition to corrosion resistance, the stainless steel elastic coupling also increases the torque capacity and rigidity, and can even be twice as high as that of similar products made of aluminum alloy.However, this increased torque and rigidity will be offset to a certain extent by the increased mass and inertia.Sometimes the negative impact will outweigh its advantages, so users have to look for other forms of couplings.
