standard, though it remains a critical reference for legacy equipment and specific industrial assemblies. DIN 5462 - ISO 14 - 1982 - Spline | PDF - Scribd

Note: ISO 14:1982 (Straight-sided splines) is very similar to DIN 5462 but not identical in all tolerances.

The DIN 5462 profile is perhaps best known in the . It is standard for connecting Power Take-Offs (PTOs) to hydraulic pumps, especially on European trucks and machinery. 6x21x25: Often found on smaller pumps and PTOs.

DIN 5462 is a foundational document in mechanical engineering history, defining the "Light Series" for straight-sided metric splines. While it has been replaced by for all new designs, it remains a crucial reference for maintaining legacy European machinery, agricultural PTO drives, and hydraulic systems. The hunt for an "exclusive" PDF usually stems from the need to match a specific, older B8x32x36 spline shaft found in the field—a geometry that, while historic, remains mechanically relevant today.

(Major Diameter / Outside Diameter): The outermost diameter measured across the tips of the splines.

DIN 5462 is a German standard that specifies the dimensions and tolerances for involute splines with a . These splines are used to connect shafts and hubs, allowing for the transmission of high torque loads.

: These profiles typically utilize the inside diameter for alignment, though centering can vary based on manufacturing methods like hobbing.

: Used for heavy-duty truck and trailer power take-offs, often paired with an ISO 7653 4-bolt flange.

: DIN 5462 typically uses internal centering (on the minor diameter ).

Understanding the DIN 5462 Spline Standard: A Technical Overview

One key feature of the standard is its specification of 8-key metric parallel (straight-sided) splines , primarily used for heavy-duty hydraulic pump and Power Take Off (PTO) applications.
