This Tsubaki RS50 finished-bore sprocket, Type 1B, is delivered with its bore, keyway and set-screw holes already machined, so it can be mounted directly on a standard shaft. This saves machining time and ensures consistent fit for replacement parts. It is used for RS50 chain drives on conveyors and general machinery.
