Product Description
Handwheels with 11″ Leadscrew, Thrust, and Nut
Don’t reinvent the wheel! If you need to move a small slide or object a controlled distance, these parts offer a convenient and economical way to do it with off-the-shelf parts. Sherline handwheels can be purchased as a set with a leadscrew of the appropriate thread, a thrust collar, and a brass nut. The replaceable nut can be secured in a predrilled hole in the part to be moved using a set screw. (In place of the nut, the leadscrew could be simply inserted into a hole drilled and tapped with the appropriate thread in the part to be moved, although using the brass nut means the least expensive part is the one that is replaced when worn out.) The collar is attached to the fixed portion of your design with a single screw (provided). Also included is a backlash nut and a lock to secure it, which allows backlash to be controlled on the leadscrew if desired. The leadscrew is over 11″ long and is available in inch (1/4-20) or metric (6.3 x 1 mm) thread pitches and matching handwheel graduations. One rotation of the handwheel drives an inch leadscrew .050″ while a metric leadscrew moves 1 mm. Inch handwheels have 50 graduations representing .001″, and metric handwheels have 100 graduations representing .01 mm.
