Full title and description

ASME B29.200-2001 (R2021) — Welded‑Steel‑Type Mill Chains, Welded‑Steel‑Type Drag Chains, Attachments, and Sprocket Teeth. This American National Standard consolidates ASME B29.16M (mill chains) and ASME B29.18M (drag chains) into a single document covering chain dimensions, attachments, sprocket‑tooth form and sprocket design data for welded steel chains used in material handling and drive applications.

Abstract

This standard specifies the geometry, interchangeability dimensions, minimum tensile ratings, attachment types, clearance/tolerance data and sprocket tooth form factors for welded‑steel mill and drag chains. It includes tables of general chain dimensions, barrel cross sections, attachment configurations, measuring and checking loads, and sprocket tolerances to support design, manufacture and replacement of chain and sprocket components.

Scope

Defines welded‑steel type mill and drag chains and associated attachments and sprocket teeth required for interchangeability and safe, consistent performance. The scope covers dimensional data, minimum ultimate tensile strengths, attachment configurations (A‑, C‑, F‑ and wing types), clearance and tolerance limits, sprocket tooth form factors, and guidance for measuring/inspecting chain length and integrity. The standard is intended for designers, manufacturers and users of welded steel chains in forest products, material‑handling and general industrial applications.

Key topics and requirements

• Consolidated definitions and designations for welded‑steel mill and drag chains (combines B29.16M and B29.18M content).
• General chain proportions and interchangeability dimensions (tables of controlling dimensions).
• Minimum ultimate tensile strength (M.U.T.S.) ratings and measuring/checking loads.
• Attachment types and recommended dimensions for common attachment styles (A1, C1, wing‑type, etc.).
• Sprocket tooth form factors, maximum eccentricity and face runout tolerances for sprockets mating with welded chains.
• Metric equivalents for dimensions to support international interchangeability.

Typical use and users

Used by mechanical designers, chain and sprocket manufacturers, maintenance engineers, procurement specialists and standards librarians. Typical applications include forest‑products mills, conveyors, drag conveyors, material handling systems, heavy‑duty drives and any industrial application requiring standardized welded steel chains and matching sprockets.

Related standards

FAQ

Q: What is this standard?

A: ASME B29.200‑2001 (R2021) is the ASME standard that consolidates welded‑steel‑type mill and drag chain requirements, including attachments and sprocket teeth, into a single document for design and interchangeability.

Q: What does it cover?

A: It covers chain dimensions, nominal sizes, M.U.T.S. ratings, attachment types and dimensions, sprocket tooth form factors and sprocket tolerances, plus measurement and inspection guidance for checking chain length and fitting.

Q: Who typically uses it?

A: Mechanical designers, chain/sprocket manufacturers, maintenance and reliability engineers, and purchasing/procurement teams in industries using welded steel chains (e.g., forest products, conveyors, material handling).

Q: Is it current or superseded?

A: The document is the 2001 edition and has been reaffirmed (R2021). Users should check ASME/ANSI publication channels for any newer revisions or superseding editions before relying on it for new designs.

Q: Is it part of a series?

A: Yes — it is part of the ASME B29 family of chain and power‑transmission standards (for example, B29.1 for precision roller chains); historically it consolidates B29.16M and B29.18M content.
