08B-1 finished bore sprockets

08B-1 finished bore sprockets are simplex hub sprockets for 08B-1 chain of 1/2" (12.7 mm) pitch to DIN 8187 / ISO 606. 08B chain is one of the most widely used in Europe - in agricultural machinery, conveyors, presses and winches.

08B-1 finished bore sprockets - fitting on a keyed shaft with no machining

You choose a sprocket with a bore equal to the shaft diameter, slide it onto the keyed shaft and secure it against sliding - with no turning, keyway cutting or extra machining costs. It is the fastest way to repair an 08B drive, and a wide choice of tooth count and bore diameter combinations lets you hit the right size without compromise.

08B-1 sprockets in C45 steel with bores for various shaft diameters

08B-1 simplex sprockets in C45 steel with bores in many diameters - the D value is given in the product name. Sprockets for 081, 083/084 and 085 chains of the same pitch but different design can be found in the Hub sprockets group.

Choosing the bore for the shaft - frequently asked questions about 08B-1 finished bore sprockets

Which bore should I choose for a 25 mm shaft?

Choose a sprocket with bore D=25. The diameter in the name corresponds to the nominal shaft diameter, and the keyway is cut to suit this diameter.
