28B-3 triplex plate sprockets

28B-3 plate sprockets are plate wheels with three tooth rims for triplex 28B-3 chain of 1 3/4" (44.45 mm) pitch to DIN 8187 / ISO 606. They work in drives where the chain transmits exceptionally high forces - in mining conveyors, mills, rolling mills and large mixers.

28B-3 triplex plate wheels - enormous torque without a larger pitch

Three chain strands let you transmit enormous torque without resorting to a larger pitch. A plate wheel without a hub simplifies the transport and machining of a large sprocket, and you make the mounting exactly for the shaft and bearing arrangement of your machine. When the rim wears you replace only the plate.
