ASME B29.11M-1994 PDF

Full title and description

St ASME B29.11M-1994 — Combination Chains, Attachments, and Sprocket Teeth. This ASME metric standard specifies the form, dimensions, attachments, and basic interchangeability requirements for combination chains and the sprocket teeth that engage them; it was later consolidated into a broader ASME chain standard.

Abstract

ASME B29.11M-1994 defines general chain proportions, link and attachment dimensions, proof and measuring loads, and sprocket tooth considerations for combination chains (block links alternating with sidebar links). The standard was developed to promote interchangeability between manufacturers and to provide tables of controlling dimensions and test/load values. The B29.11M text was subsequently consolidated with related ASME chain standards into ASME B29.400 (2001) for ease of use.

General information

• Status: Consolidated / superseded (original B29.11M-1994 consolidated into ASME B29.400-2001; users should consult the consolidated/superseding documents for the most current requirements).
• Publication date: 1994 (designation includes the year 1994).
• Publisher: American Society of Mechanical Engineers (ASME).
• ICS / categories: Industrial chains and related components — typically classified under ICS codes for iron & steel products and chain drives (e.g., 77.140.65 / 21.220.30).
• Edition / version: Original ASME metric edition released 1994 (commonly cited as B29.11M-1994); technical content later incorporated into ASME B29.400-2001.
• Number of pages: Original B29.11M-1994 page count is not widely published separately; the consolidation product ASME B29.400-2001 (which includes B29.11M content) is listed at about 36 pages.

Scope

This standard covers combination chains (block-link type chains with alternating sidebar links), the dimensions and types of attachments used with those chains, and the geometry of sprocket teeth that engage the chains. It provides tables of standard link dimensions, clearances, proof and measuring loads, and nominal attachment types to ensure interchangeability and safe function in conveyor, elevator, and mill applications. For the current unified guidance, the material was consolidated into ASME B29.400-2001 which brings together related chain types and sprocket provisions.

Key topics and requirements

• Definition and designation of combination-chain geometry (pitch, link form, block-link/barrel details).
• Dimensional tables for standard chain sizes, maximum/minimum controlling dimensions for interchangeable links, and chain clearance dimensions.
• Specification of common attachment types and their controlling dimensions (e.g., A‑type, K‑type attachments used with conveyor chains).
• Proof test and measuring loads, and strand-length/measuring procedures for checking chain wear and elongation.
• Sprocket-tooth form guidance to ensure correct meshing with combination chains.
• Interchangeability and manufacturing tolerances to permit direct replacement between different manufacturers.

Typical use and users

Engineers, maintenance teams, chain and sprocket manufacturers, conveyor system designers, mill and pulp/lumber industry practitioners, and purchasers of replacement chain components consult this standard for component dimensions, interchangeability criteria, and test/load requirements. It is used when specifying chain assemblies for conveyors, elevators, transfer systems, and other material-handling equipment where combination-chain types are employed.

Related standards

Standards and documents commonly referenced with or that supersede/relate to B29.11M-1994 include ASME B29.14M-1996 (H‑type mill chains), ASME B29.15M (roller-type conveyor chains), the consolidated ASME B29.400-2001 (which incorporates B29.11M content), and later ASME chain/sprocket publications or reaffirmations. Internationally, ISO 1977 (conveyor chains, attachments and sprockets) covers similar topics for metric conveyor-chain interchangeability.
