Roller Link D. — An inside link consisting of two inside plates, two bushings, and two rollers. Pin Link G and E. — An outside link consisting of two pin-link plates assembled with two pins. Inside Plate A. — One of the plates forming the tension members of a roller link. Pin Link Plate E. — One of the plates forming the tension members of a pin link. Pin F. — A stud articulating within a bushing of an inside link and secured at its ends by the pin-link plates. Assembled Pins G. — Two pins assembled with one pin-link plate. Connecting-Link G and I. — A pin link having one side plate detachable. Connecting-Link Plate I. — The detachable pin-link plate belonging to a connecting link. It is retained by cotter pins or by a one-piece spring clip (not shown). Connecting Link Assembly M. — A unit designed to connect two roller links. Offset Link L. — A link consisting of two offset plates assembled with a bushing and roller at one end and an offset link pin at the other. Offset Plate J. — One of the plates forming the tension members of the offset link. Offset Link Pin K. — A pin used in offset links. Bushing B. — A cylindrical bearing in which the pin turns. Roller C. — A ring or thimble which turns over a bushing. Standard double-pitch roller chains are like standard roller chains, except that their link plates have twice the pitch of the corresponding standard-pitch chain. Their design con forms to specifications in the ANSI/ASME standard for double-pitch power transmission roller chains and sprockets ANSI/ASME B29.100-2011 (R2016). They are especially use- ful for low speeds, moderate loads, or long center distances.
