HTD 14M pilot bore timing pulleys

14M pilot bore timing pulleys are large HTD 14M pulleys with a pilot bore. The bore is machined for the shaft, and the keyway is cut to DIN 6885 - a good solution for shafts of non-standard diameters.

HTD 14M pilot bore synchronous pulleys - a cheaper solution for large shafts

You prepare the pulley exactly for the machine shaft, without buying a bush - with large shaft diameters this is often the cheaper solution. A well-bored hole gives secure seating and low runout. Smaller pulleys are made of C45 steel, and larger ones of grey cast iron.

HTD 14M timing pulleys with a pilot bore in several widths

HTD 14M pulleys with a pilot bore, for several belt widths and in a wide choice of tooth counts. The belt width is given in the pulley name, and the dimensions of the hub and pilot bore - on the product page.
