Useful Engineering Formulas Horsepower Horsepower (HP) is the rate of doing work. One HP is equal to raising 33,000 lbs. one foot in one min. HP = Force x FPM 33,000 HP = Torque (Inch Pounds) x RPM 63,025 HP = Torque (Foot Pounds) x RPM 5,252 Torque Torque (T) is a turning movement or twisting effort.

Wood’s ® Sure-Grip QD Bushings • Provide a True Clamp Fit • Are Easy to Install and Remove • Permit Four-Way Mounting P-1686-TBW

SAE Sure-Grip® Bushings Features Sure-Grip® “Quick Detachable” bushings are easy to install and remove. They are split through flange and taper to provide a true clamp on the shaft that is the equivalent of a shrink fit. All sizes except JA and QT have a setscrew over the key to help maintain the Precise taper (3/4 in. per ft. on diameter) provides proper wedging action. 6-hole drilling (most sizes) makes installation and removal quick and easy. Keyseat 180° from split. Cap screws used to secure bushings to sheave and to remove bushing from sheave. Saw cut through flange and taper (and...
