This 15 tooth helical gear is used in the hand fine adjustment mechanism on most Polar EL, Polar CE, Polar CS, and Polar ST paper cutters. It measures 2-3/4" long by 1-1/4" diameter at the large end. It has been machined from Delrin plastic. Included with each gear is an INA needle bearing which is pre-installed inside the gear.
