10B-3 triplex Taper-Lock sprockets

10B-3 Taper-Lock sprockets are triplex sprockets for 10B-3 chain of 5/8" (15.875 mm) pitch to DIN 8187 / ISO 606. They combine the high load capacity of a triplex chain with convenient mounting on a taper bush.

10B-3 triplex Taper-Lock sprockets - a heavy sprocket with no machining

A heavy triplex sprocket is difficult to machine accurately and remove from the shaft - the Taper-Lock seat solves both problems. The sprocket is centred as soon as the bush is tightened, and comes off without a puller during servicing. The hardened tooth version copes better with frequent starts under load.
