This Standard is a consolidation and revision of three ASME chain standards: ASME B29.6, Steel Detachable Link Chains, Attachments, and Sprockets; ASME B29.19, Agricultural Roller Chains, Attachments, and Sprockets; and ASME B29.25, Open Barrel Steel Pintle-Type Conveyor Chains, Attachments, and Sprockets. The new Standard was designated ASME B29.300. B29.6 - Steel Detachable Link Chains, Attachments, and Sprockets: This Standard establishes, in the main, only those dimensions that will provide for interchangeability of the chains in use without restricting the chain manufacturers in their overall design. A steel detachable link chain is a series of successively assembled steel links in which the end bars articulate inside the hook. The chain is detached by flexing it and driving the end of the bar out of the adjoining hook. The main topics are (a) General chain proportions and designations; (b) Attachments; and (c) Sprockets. There are also Tables for (a) Plain link; (b) A1, A2, C1, C15, G27, HB4, K1, SD, SH and AS attachments; (c) Coupler links and pins; (d) Sprockets – Maximum eccentricity and face runout at root diameter; and (e) Sprocket factors.B29.19 - Agricultural Roller Chains, Attachments, and Sprockets: This Standard establishes essentially only those dimensions that will provide for interchangeability of the chains in use without restricting the chain manufacturers in their overall designs. This Standard covers a series of alternately assembled roller links and pin links in which the pins articulate inside the bushings and the rollers are free to turn on the bushings. The main topics are (a) General chain proportions and designations; (b) Chain dimensions; (c) Attachment dimensions; (d) Sprockets. There are also Table for (a) General chain dimensions; and (b) C11E, C13E, C6E, C17E, A19, F14 and K39M attachments.B29.25 - Open Barrel Steel Pintle-Type Conveyor Chains, Attachments, and Sprockets: The open barrel steel pintle chain was originally developed in 1962 for the agricultural implement industry. Open barrel steel pintle chains are a series of one-piece formed links, connected by pins that articulate within the barrels of adjacent links. Each link has a barrel end and an open end. The pins are fixed against rotation by mechanical locks or interference fits at the open end of the link. The barrels are open, leaving the pins exposed on one side. Sprocket contact is made against the barrel or against the exposed pin. The main topics are (a) General chain proportions and designations; (b) Attachments; and (c) Sprockets. There are also Tables for (a) Minimum and maximum controlling dimensions for interchangeable chain links; and (b) AS and C1 attachments.
