WebFULL DEPTH TEETH are those in which the working depth equals 2.000 divided by the normal diametral pitch. GEAR is a machine part with gear teeth. When two gears run together, the one with the larger number of teeth is called the gear. HUB DIAMETER is outside diameter of a gear, sprocket or coupling hub. WebOur portfolio of custom gear and transmission products includes spur, helical, and worm gear sets with capacities up to 80" in diameter. We also produce bevel, rack & pinion, and planetary gears and specialize in internal shaping. Along with flat and hex shafts, gear features include British Standard Metric, cycloidal, involute, straight, and ...
