Can compensate two shafts relative offset, you can damping and cushioning. Small radial size, simple structure, no lubrication, higher carrying capacity and easy maintenance. Replacing the elastomer to move axially. For coaxial connection, frequent starting, reversing changes, medium speed, medium torque drive shafts and high reliability requirements of the work the work area. Does not apply to heavy load, low-speed and axial dimensions affected by the storm system, the replacement of the elastic element shaft alignment difficulties after the two parts. XL Type - Basic; XLD type - expanding shaft hole.
