32B-2 duplex hub sprockets

32B-2 hub sprockets have two tooth rims and work with duplex 32B-2 chain of 2" (50.8 mm) pitch to DIN 8187 / ISO 606. It is one of the strongest hub sprocket versions, designed for drives with very high loads.

32B-2 duplex sprocket - load capacity beyond any simplex chain

A second strand of 32B chain gives a load capacity that no B series simplex chain can provide. The thick-walled C45 steel hub lets you bore a hole for a large-diameter shaft, and its height provides a long keyway that reliably transmits the torque.

Frequently asked questions about sprockets for 32B-2 chain

How should the chain in a 32B-2 drive be lubricated?

At low speeds, regular manual or drip lubrication is usually sufficient. The lubricant should reach between the plates, the pins and bushes - lubricating the rollers alone is not enough.
