20B-3 triplex plate sprockets

20B-3 plate sprockets are triplex plate wheels for 20B-3 chain of 1 1/4" (31.75 mm) pitch to DIN 8187 / ISO 606. They are designed for the heaviest industrial drives and large conveyors.

20B-3 triplex plate wheels - very high forces and easier transport

A triplex chain of this size transmits very high forces, and a plate wheel without a hub lets you build a sprocket matched to a specific machine. A flat plate is easier to transport than a ready-made sprocket, and on site you weld it to a hub or bolt it to a flange.

20B-3 triplex drive or a larger pitch - customer questions

Can I replace a triplex drive with a larger pitch?

Yes, but this requires replacing the sprockets and chain and usually more space. A triplex drive lets you keep smaller sprocket diameters with similar load capacity.
