FAQ Question?What is the correct procedure for installing a 2012 taper bush?Answer:Clean the shaft, bore, and the outside of the bush. Insert the bush into the pulley or sprocket hub, aligning the holes. Lightly oil the grub screws and thread them into the holes. Slide the assembly onto the shaft, position it, and then progressively tighten the screws to the manufacturer’s recommended torque value to ensure an even and secure clamp.Question?Is this 5/8 inch bore compatible with a 16mm shaft?Answer:No, a 5/8 inch bore is exactly 15.875mm. While very close to 16mm, using it on a 16mm shaft could cause installation issues or an improper fit, leading to vibration and premature wear. It is crucial to use a bush with the exact bore size matching your shaft diameter.Question?What does the ‘2012’ designation signify?Answer:’2012′ is a standard size code for taper lock bushes. It defines key physical dimensions like the overall length, the large end diameter of the taper, and the bolt circle for the grub screws. This standardization allows for interchangeability between different manufacturers for the same size code. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
