32B (2") hub sprockets

32B hub sprockets are the largest B series hub sprockets in our range. They work with 32B roller chain of 2" (50.8 mm) pitch to DIN 8187 / ISO 606, which runs at low speeds and very high forces - in mines, aggregate processing plants, steelworks and large conveying installations.

32B hub sprockets - a complete drive component for heavy machinery

A hub sprocket is a complete drive component - you bore the hole for the shaft and cut a keyway, without welding or making a mounting. C45 steel withstands shocks and high loads well, and the tall hub reliably transmits the torque. Compliance with the standard ensures the sprocket works with 32B chain from any manufacturer.

Sprockets for 32B chain - customer questions

How do I move and install a 32B sprocket?

The largest sprockets weigh several hundred kilograms, so lifting equipment is needed to move and install them. The weight of each sprocket is given on the product page.

Does a 32B sprocket fit ASA 160 chain?

No. ASA 160 (32A) chain has the same pitch, but a different roller and inner width. A series sprockets can be found in the ASA sprockets group.
