Specifications:
The document outlines specifications for precision joints, specifically types GA and HA. Type GA features a plain bearing with a maximum speed of 1000 min-1, while Type HA includes a needle bearing with a maximum speed of 4000 min-1. Both types are extendable and can bridge larger shaft distances with a maximum articulation angle of 45° for each joint. They are available with quick locking options (GR; HR) and can be customized with finish bores (H7), keyways, threads for setscrews, and square or hexagon bores.

Dimensions and Sizes:
The document provides detailed dimensions for various sizes of joints, including new sizes 01 GA and 02 GA. It includes measurements for diameter (d1, d2), mounting lengths (Lmin./Lmax.), and other critical dimensions. The finish bore is specified as H7, and keyways conform to DIN 6885 sheet 1 (JS9).

Procedures:
The calculation of mounting lengths L and X (Stroke) is provided, with formulas for determining Lmin and Lmax. The document specifies that Lmin is calculated as L2 + B + X + L2, while Lmax is calculated as Lmax - 2 • L2 - B.

Standards and Recommendations:
The joints are manufactured according to DIN 808 standards, ensuring compatibility and precision. The document recommends using these joints for applications requiring precision and extendability, with options for customization based on customer requirements.

Key Data from Tables:
The tables in the document list various sizes and their corresponding dimensions, such as diameter, length, and bore specifications. These tables are crucial for selecting the appropriate joint size for specific applications.
