NEW OPTION ADDED High performance metal disc coupling

SERV OFLEX High-stiffness and low-inertia couplings Metal disc couplings developed for high-speed, high-precision positioning, and ultra-precise control of servomotors, etc. While achieving high torsional stiffness, high torque, low inertia, and high response speed, these couplings are also flexible in the parallel misalignment direction, in the angular directions, and in the axial direction. This model has a single element type that emphasizes stiffness and a double element type that emphasizes flexibility. A wide variety of options such as a tapered shaft, length-specified special order, and...

Heat rejection The stainless-steel plate spring reduces thermal conduction from a servo motor to the driven shaft, which also reduces variations in accuracy caused by thermal expansion.

For length-specified special order parts SFC (DA2) type spacer length can be changed to attain the necessary distance between shafts. Specify the length in 1 mm units. Shape type * Types A / B / C are automatically specified by Miki Pulley according to the combination of bore diameters you select, and cannot be specified by the customer. * Check the "Standard Bore Diameters" for SFC DA2 as there may be limitations on the rated torque caused by the holding power of the coupling shaft section. * Max. rotation speed does not take into account dynamic balance. * The moment of inertia and mass are...
