: Used for heavy-duty truck and trailer power take-offs, often paired with an ISO 7653 4-bolt flange.
Engineers, machinists, and quality control inspectors require the original, unedited documentation to program CNC machinery or verify production tolerances.
Mounting a gear pump onto a power take-off (PTO). Agriculture: Connecting tractor implements. Construction Machinery: Driving hydraulic components.
The parallel flanks distribute high torsional loads evenly over a large surface area. This minimizes localized stress concentrations at the root of the tooth.

Engineers frequently confuse DIN 5462 with the broader (or DIN 5463) standards, which also govern straight-sided splines.
Explicitly features a 4-spline design. It is highly specialized for mobile hydraulics and truck PTO systems.
The DIN 5462 standard, established by the German Institute for Standardization ( Deutsches Institut für Normung ), specifies the dimensions and tolerances for straight-sided (parallel) splines with internal centering. Unlike involute splines that feature curved tooth flanks, DIN 5462 utilizes a straight, parallel tooth profile.
While the official standard tables are extensive, the following provides a representative overview of the nominal dimensions defined by DIN 5462: : Used for heavy-duty truck and trailer power
Below are the nominal dimensions for the DIN 5462 Light Series. All measurements are in millimeters (mm). Nominal Size (N x d x D) Number of Keys (N) Inside/Minor Dia (d) Outside/Major Dia (D) Key Width (B) 6 x 23 x 26 6 x 26 x 30 6 x 28 x 32 8 x 32 x 36 8 x 36 x 40 8 x 42 x 46 8 x 46 x 50 🛠️ Key Design Details Centering: The standard typically uses internal centering (on the minor diameter Tolerances: Common fits include for the bore and for the shaft, depending on the application.

The DIN 5462 spline standard is a widely used and well-established specification for splines. Its comprehensive coverage of dimensions, tolerances, and material requirements ensures the interchangeability and reliability of splines in various industries. By understanding the key features and applications of DIN 5462, engineers and manufacturers can design and produce high-quality splines that meet the demands of modern mechanical systems.
is the American standard for involute splines. It defines spline teeth based on diametral pitch (DP) rather than the metric module system used in DIN standards. ANSI B92.1 splines are found primarily in North American automotive, aerospace, and industrial applications. DIN 5462, by contrast, is metric-based and is most commonly encountered in European-designed equipment.
: Typically 6 to 10 keys, depending on the nominal size. Agriculture: Connecting tractor implements
The specifies the parameters for straight-sided, internal and external splines with four splines in the series. It is a critical engineering benchmark primarily used for heavy-duty power transmission in automotive, hydraulic, and agricultural machinery.
Power Take-Off (PTO) gearboxes mounted to truck transmissions frequently use a DIN 5462 4-bolt, 4-spline output interface.
