Conveyor Chains Standards
Standards for chains address the wide range of applications chains have in the conveyor field, from merely being components that convey power in other conveyor designs to being the main player. In addition to specifying the characteristics of the chains themselves, these standards also address the associated attachments, sprocket teeth, connector units, and so forth, providing for a complete picture.
ISO 1977:2006
Conveyor chains, attachments and sprockets
ISO 1977:2006 specifies the characteristics of bush, plain and flanged roller chains of both solid and hollow bearing pin types designed for general conveying and mechanical handling duties, together with associated chain sprockets and attachments. The chain dimensions it specifies will ensure interchangeability of complete chains and individual links for repair purposes. It is applicable to sprockets with from 6 to 40 teeth. Control criteria for sprockets are defined to ensure correct meshing, operation and transmission of load in use under normal operating conditions. Specifications are also given for K attachments and deep plates for use with the conformant conveyor chains.
ASME B29.15M-1997 (R2021)
Steel Roller Type Conveyor Chains, Attachments, and Sprocket Teeth (B29.15M - 1997)
This Standard includes information for Steel Roller Type Conveyor Chains, Attachments and Sprocket Teeth: A series of roller links having steel bushings with rollers to contact the sprocket teeth, alternating with links comprised of sidebars and pins, which articulate in the steel bushings of the roller link. The main topics are (a) General Chain Proportions and Designations; (b) Dimensions of chain links and of attachments; and (c) Sprocket Tooth Form. There are also Tables for (a) General Chain Dimensions , Minimum Ultimate Tensile Strength, Strand Length and Measuring Load (b) Maximum and Minimum Controlling Dimensions for Interchangeable Chain Links; (c) Chain Clearance Dimensions; (d) A-1, A-2, A-42, K-1, K-2 Attachments; (e) Maximum Eccentricity and Face Runout Tolerances of Sprockets; and (f) Sprocket Factors.
ASME B29.17M-1998 (R2018)
Hinge Type Flat Top Conveyor Chains and Sprocket Teeth
This Standard contains information for Hinge-type Flat-top Conveyor Chains and Sprocket Teeth: A series of steel (carbon or stainless) flat surfaces of various widths as specified herein made integral with hinge-like barrels on each side. These barrels are designed to interlace so that pins inserted through the holes formed by the barrels connect adjacent links, thus forming a continuous length of flat top conveyor chain free to flex in one direction. Pins are retained by press fit and/or heading with respect to the barrels of one link while being a free or slip fit with respect to the interlaced barrels of the adjacent link. The chain so formed is driven by meshing the curl outside diameters with sprocket teeth. Plastic hinge-type flat-top conveyor chains are similar to steel type flat top chains except that the chain links are molded of plastic material. Pins are usually made of stainless steel and may be retained by press fit or knurls. The main topics are (a) General chain proportions and designations; (b) Explanation of the chain numbering system; (c) Chain dimensions; and (d) Sprocket tooth form – general. There are also Tables for (a) General chain dimensions, Minimum Ultimate Tensile Strength and Measuring load for checking chain length; (b) Maximum and minimum controlling dimensions for interchangeable links; (c) Chain clearance dimensions; (d) Standard pitch diameter, maximum outside and bottom diameter, and pressure angle limits for normal range of sprocket teeth available with Type B tooth form sprockets; and (e) Maximum eccentricity and face runout tolerances of sprocket teeth.
ASME B29.27-2002 (R2021)
Single Pitch and Double Pitch Hollow Pin Conveyor Chains and Attachments
This Standard covers the dimensional limits required for chain interchangeability on sprockets. It does not provide for interconnectability of chains or individual links from different manufacturers. Hollow-pin chain, double pitch is a series of alternately assembled roller links and pin links in which the hollow pins articulate inside the bushings. The pitch of the link plates is twice that of the link plates of the base series chain. Pin link plates and roller link plates have identical straight-edge contours. Chains may have large rollers that are intended for use when the conveyed load is carried by the rollers. Hollow-pin chain, single-pitch is a series of alternately assembled roller links and pin links in which the hollow pins articulate inside the bushings. The main topics are (a) Hollow pin chains; and (b) Sprockets. There is a Table on General chain dimensions, Limiting dimensions for interchangeability, Measuring loads and Ultimate tensile strengths.
ISO 1082:1990
Mining - Shackle type connector units for chain conveyors
This second edition cancels and replaces the first edition (1984). Specifies the requirements for a range of connector units. Each unit consists of the following components: shackle type connector, connector bolt, connector nut. It does not indicate a complete design, but it gives sufficient detail to ensure dimensional compatibility with chains complying with ISO 610 and scraper bars complying with ISO 5612.
ISO 1275:2006
Double-pitch precision roller chains, attachments and associated chain sprockets for transmission and conveyors
ISO 1275.2006 specifies requirements for double-pitch precision roller chains suitable for the mechanical transmission of power and for conveyors, together with those for their associated sprockets. It covers dimensions, tolerances, length measurement, preloading and minimum tensile strengths. These double-pitch chains have been derived from some of the short-pitch transmission precision roller chains covered by ISO 606 having certain common dimensions but of double the pitch. The chains are intended for use under less onerous conditions with respect to speed and power transmitted than are the base chains from which they are derived. ISO 1275.2006 primarily applies to sprockets with 5 to 75 teeth inclusive (with intermediate numbers of teeth 5 and a half to 74 and a half inclusive). The preferred numbers of teeth are 7, 9, 10, 11, 13, 19, 27, 38 and 57.

Specifies the requirements for a range of scraper bars for use in twin outboard chain assemblies made from chains complying with ISO 610 and associated shackle type connectors complying with ISO 1082. The figures illustrate shapes and reference quantities of concern. Tabulates the dimensions and strength rating of scraper bars.
ISO 5613:1984
Mining - Drive sprocket assemblies for chain conveyors
Specifies the requirements for a range of sprocket assemblies for use in twin outboard chain assemblies. These assemblies incorporate sprocket rings designed to accept chains complying with ISO 610, shackle type connectors complying with ISO 1082, and scraper bars complying with ISO 5612. It tabulates the dimensions and the figures illustrate shapes and reference quantities of concern. An annex gives design formulae.
ISO 610:1990
High-tensile steel chains (round link) for chain conveyors and coal ploughs
This International Standard specifies the requirements for a range of high-grade special purpose calibrated, high-tensile, electrically welded, steel chains (round link) for use with machines and equipment in mining, such as the following: conveyors, flexible and rigid, of the chain type, chain belt conveyors, gate end and stage loaders: coal ploughs, coal cutters and power loaders; bucket elevators; other similar machines used in mines. This International Standard covers a size range from 14 mm to 30 mm. Three grades of quality (B, C and D) are specified with regard to the mechanical properties of chain. The values given for grade D in tables 3, 4, 7 and 8 are, however, provisional. Chains covered by this International Standard are not designed for lifting appliances, such as cranes and slings.
