32B-3 hub sprockets are sprockets with three tooth rims for triplex 32B-3 chain of 2" (50.8 mm) pitch to DIN 8187 / ISO 606. They are the heaviest B series hub sprockets in our range, designed for drives in which the chain transmits exceptionally high torque.
32B-3 sprockets - the highest load capacity among our hub sprockets
Three strands of the largest B series chain we offer mean the highest load capacity our hub sprockets provide. Such a sprocket only needs to be machined for the shaft - no welding or making a mounting - and the tall C45 steel hub guides the very wide tooth rim stably.
32B-3 triplex sprockets in C45 steel - a very wide tooth rim
32B-3 triplex hub sprockets in C45 steel with unhardened teeth. The sprocket is very wide - before ordering, check the dimensions and weight on the product page and make sure it will fit on the shaft and under the guard.
32B-3 triplex sprockets - customer questions
Why does a triplex chain require precise sprocket alignment?
The load is spread evenly over three strands only when the sprockets lie in one plane and the shafts are parallel. Any deviation overloads the outer strand and accelerates wear.
