Related QD Bushings | Quick Disconnect Bushings
QD bushings are utilized throughout the industrial power transmission and agricultural industry for various sprockets, sheaves, pulleys, and synchronized drives. They are designed for easy installation and easy uninstallation; they are also commonly referred to as quick-disconnect bushings. QD bushings can help conventional mounting with the flange outboard and reverse mounting to where the flange is inboard and utilize a single split that extends through the entire bushing length. Our QD bushings interchange with other brands and are made from high-grade steel precision machined for perfect application fitment. QD bushings’ benefits over different styles include; ease of installation/ uninstall, superior holding power, and extreme strengths. We stock all the standard sizes of QD bushings and supply custom QD bushings upon request, including stainless steel ones. QD bushings are found in some of the most rugged applications worldwide; contact our customer service team today for a quote or additional information on our premium QD bushings.

Why Does the Belt Fall off the Pulley by Itself When Driving?
1. The belt falls off the pulley by itself during transmission; it may be that the belt is installed too loosely;
2. It is also possible that the pulley and the motor drive end are unbalanced and not on the same level;
3. Check whether the pulley bearing is damaged and whether the pulley is vertical.
4. Check whether the drive end is firmly fixed and whether the belt model matches the pulley.
