FAQ What is the correct procedure for installing a 3020 taper bush?First, ensure the shaft, bore of the bush, and inner bore of the pulley are clean and free of oil or debris. Insert the bush into the pulley, aligning the holes. Lightly oil the threads of the set screws and insert them. Slide the complete assembly onto the shaft, position it correctly, and then tighten the screws alternately and evenly to the manufacturer’s recommended torque. What is the standard keyway size for a 2-inch bore on a 3020 taper bush?According to ANSI/BS standards, a 2-inch bore typically requires a 1/2 inch width x 1/4 inch depth keyway. However, it is always best to confirm this with the official Optibelt technical documentation or measure the existing keyway to ensure a proper fit. Can this cast iron bush be used in high-vibration environments?Yes, the taper lock design provides a high clamping force and excellent concentricity, which makes it very effective in resisting vibration and shock loads. For applications with extreme vibration, it is good practice to perform periodic checks to ensure the set screws remain at their specified torque. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
