Din 5464 Standard Pdf [ RECOMMENDED - 2024 ]

DIN 5464 splines are preferred in heavy-duty machinery where space is limited but torque requirements are high.

Typically flank-centered , though internal or diameter centering may be defined for specific applications.

The standard provides the geometry, dimensions, and tolerances necessary for manufacturing and inspecting these heavy-duty spline connections. Straight-sided splines - Heavy series. din 5464 standard pdf

Provides the DIN 5464 PDF with immediate download options.

The increased number of keys/teeth allows for greater torque transmission than the light or medium series (such as DIN 5462 or DIN 5463). DIN 5464 splines are preferred in heavy-duty machinery

The document is approximately long and is published in both German and English.
