Servoflex SFU series datasheets

Product catalog summary
Overview: The document provides detailed specifications and dimensions for SERVOFLEX SFU SS and DS metal disc couplings, which are used in mechanical systems to connect rotating shafts.
Specifications: The datasheet outlines the rated torque, misalignment tolerances (parallel, angular, axial), maximum rotation speed, torsional stiffness, axial stiffness, moment of inertia, and mass for various models of the SFU SS and DS series. Key points include:
  • SFU SS models have higher torsional stiffness and are suitable for higher rotation speeds compared to DS models.
  • Both series allow for higher RPM with balancing.
  • Torsional stiffness values are specific to the flexible element alone.
Dimensions: The document provides detailed dimensional data for each model, including bore diameters (d1, d2), outer diameter (D), and various length measurements (N, L, LU, LS, LF, LP). It also specifies the tightening torque for mounting bolts (M1).
Ordering Information: The datasheet explains how to place an order, specifying the type (SS for single element, DS for double element), bore specifications compliant with JIS standards, and material (S45C heat-treated or equivalent).
Key Considerations:
  • Selection of the appropriate model depends on the required torque, misalignment tolerances, and rotational speed.
  • Proper balancing is necessary for achieving higher RPMs.
  • Compliance with JIS standards ensures compatibility with existing systems.
