Ball screws are the most common transmission components used as transmission elements in machinery and precision machinery. 2. Ball screws are made of carbon steel, which is more wear-resistant, greatly extending the service life of ball screws, and the life span is increased several times. 3. Less heat generation, reduced required drive power, and high axial force per unit ball screw volume. 1. Complete thread, uniform force, smooth sliding, smooth and burr-free 2. Uniform force, fine workmanship, good fastening effect 3. Mainly suitable for printers, industrial automation, packaging machinery and other fields Department unisex-adult Item Weight 6.61 pounds Manufacturer KUAOXK Item model number KUAOXK Package Dimensions 0.39 x 0.39 x 0.39 inches
