20A coil chains
Description
One roll of 20A ANSI100 marked roller chain unit contains 5 meters in length. (Certain products can be 50m or 100 meters, this is marked separately.) Each 5-meter unit package (box) contains a roll of roller chain and a piece of straight patent eye. 20A ANSI100 roller chains can be single-row (simplex, designation 20A-1), double-row (duplex, designation 20A-2) and three-row (triplex, designation 20A-3).
To be arranged later. Our colleagues will contact you!
The pitch of the 20A chains is 31.75 mm, the inner width is 18.9 mm, and the roller diameter is 19.05 mm. For roller chains marked 20A, a cotter pin marked 20A and a sprocket marked 20A must be used. When installing a chain drive, the tensile strength of the roller chains specified in the catalog must always be taken into account! Downloadable catalog under the Downloadable Documents tab.
