Spline Identification & Selection

Spline Identification & Selection

    There are hundreds of combinations of splines used in industry today and, while Lovejoy does not stock all of these splines, many are maintained in inventory while a large variety can be quickly machined for your specific needs.

    When identifying splines, it is important to know what Industry Standard the spline falls under such as ANSI B92.1A (SAE J744) or DIN5480. Manuals and data sheets provided by most original equipment manufacturers contain the necessary spine data for users to identify and order a hub with the proper spline.

    Lovejoy’s Customer Service and Technical Support teams can help pick out couplings or hubs containing most splines, but certain information will need to be provided prior to making the proper selection.

    SAE Standard Involute splines are the most common spline in use in the United States and many are represented in the ANSI chart shown on the right. Information required to identify most ANSI (SAE) splines contains the number of teeth, the diametral pitch, and the major spline diameter. Lovejoy’s ANSI splines are machined to meet the ANSI standard Class-5 fit.When specifying DIN-5480 splines, it is necessary to provide the number of teeth, the major diameter in mm, and the DIN Module number, usually in format:
    DIN 5480 x Major Dia x Module x Pressure angle (usually 30*) x number of teeth.
    Lovejoy’s DIN-5480 splines are machined to meet the DIN standard 9H fit.

    DIN-5482 metric splines, JIS splines, and SAE J499 parallel side splines, can be quoted based on individual applications.



  • L-LOC eliminates premature spline shaft maintenance or replacement
  • Reduces potentially damaging stress on equipment components
  • Quick and easy to assemble and/or removal
  • Improves the effectiveness of the connection between the hub and shaft
  • Helps reduce equipment noise often related to couplings



  • For Hytrel, dynamic torsional stiffness values are non-linear with respect to torque. Value given is for 100% of nominal torque.
  • Angular and parallel misalignment values are dependent on speed, and for rubber elements, should be adjusted according to figure 4. Hytrel® elements are only for applications where the driven component is piloted to the driver for SAE and DIN established alignments (i.e. Hydraulic pump flange-mounted to engine flywheel housing).
  • Hytrel® elements are only for applications where the driven component is piloted to the driver for essentially perfect alignment (hydraulic pump flange-mounted to engine housing).
