DIN 705 2019-03 PDF

Full title and description

STB DIN 705:2019-03 — Adjusting rings (German: Stellringe). This designation is used for the DIN 705 edition published in March 2019 and is also offered in localized/republished catalogs under the header "STB DIN 705 2019-03" by some standards resellers.

Abstract

DIN 705:2019-03 specifies dimensions and technical delivery conditions for adjusting rings (set collars) of forms A, B and C. The standard defines geometric dimensions, tolerances, materials/surface notes and requirements for delivery (e.g., whether threaded pins / grub screws are delivered assembled). It replaces the previous 2007 edition and consolidates updated normative references, an added glossary/terms section and revised tables of dimensions and delivery conditions.

Scope

This standard establishes the dimensional series, form designations (A, B, C), tolerances and technical delivery conditions for adjusting rings (set collars) used to fix components on shafts and axles. It covers material and surface considerations relevant to mechanical engineering and component supply, and specifies requirements associated with delivered set screws or pins as part of the collar assembly. It does not cover non-standard special designs outside the dimensional tables.

Key topics and requirements

• Definition of forms A, B and C for adjusting rings (geometric profiles and usage).
• Dimensional tables for inner/outer diameters, widths and fit tolerances.
• Technical delivery conditions (materials, surface protection, assembly state of threaded pins/grub screws).
• Normative references and terms (added glossary/section on definitions).
• Updated tolerances and editorial improvements over the 2007 edition.

Typical use and users

Used by mechanical engineers, machine builders, component manufacturers and suppliers of standard parts (shafts, collars, locking elements) to ensure interchangeability and consistent delivery quality of adjusting rings/set collars in drive and general mechanical engineering applications. Commercial suppliers and catalog manufacturers reference DIN 705 when producing and selling set collars in standard sizes and materials.

Related standards

Related documents include previous editions (DIN 705:2007-04) which this edition replaces, and other DIN/ISO standards covering set screws, grub screws and fastener delivery conditions (for example standards referenced within the normative references section of DIN 705). The document sits within the ICS family for rings, sleeves and collars (21.060.60).

FAQ

Q: What is this standard?

A: DIN 705:2019-03 is the DIN standard that specifies dimensions and delivery conditions for adjusting rings (set collars) of forms A, B and C; it is the 2019 revised edition of the DIN 705 series.

Q: What does it cover?

A: It covers geometric dimensions, tolerances, form designations (A/B/C), material/surface notes and technical delivery conditions including how threaded pins or grub screws are handled as part of delivery. It does not specify bespoke non‑standard collar designs outside the tabulated series.

Q: Who typically uses it?

A: Mechanical and design engineers, producers and distributors of standard parts (set collars, rings), procurement specialists specifying interchangeable components, and quality departments verifying delivered components against standard dimensions. Catalog/product pages for suppliers commonly reference DIN 705 for part conformity.

Q: Is it current or superseded?

A: The 2019-03 edition is the current DIN 705 edition that replaced DIN 705:2007-04; users migrating from older editions should adopt the 2019 dimensional tables and updated normative references.

Q: Is it part of a series?

A: Yes — DIN 705 is part of the broader family of standards addressing rings, collars and related fastening parts (ICS 21.060.60). It also relates by reference to standards for set screws/fasteners that appear in its normative references.

Q: What are the key keywords?

A: Adjusting rings; set collars; Stellringe; dimensions; tolerances; grub screw; threaded pin; technical delivery conditions; DIN 705; 2019.
