Description
Product Name: 1560-4 Hook (with Cylindrical Gear 37×1.25 – Left-hand)Product Category: Helical Gear
This product is made of 20CrMo alloy structural steel and manufactured through a sequence of precision processes: Sawing → Turning → Tapping → Reaming → Hobbing → Heat Treatment → Shot Blasting → Secondary Reaming → Surface Finishing → Screw Assembly. Every step is strictly controlled to ensure dimensional tolerance and assembly precision, thus guaranteeing smooth and durable gear transmission.
The product is featured with precise core technical parameters: pressure angle of 20°, module of 1.25, 37 teeth, helix angle of -15° (left-hand), inner diameter of 9.5mm, tooth outer diameter of 50.38mm, total length of 18mm, and a single unit weight of 0.1225kg.Benefiting from the high strength and wear resistance of 20CrMo material, as well as the advantages of heat treatment, shot blasting and other processes, this gear boasts low transmission noise and high load-bearing capacity. Specially designed for sewing equipment, it can meet the high-frequency operation requirements of the hook and provide stable and reliable power transmission for sewing machines.
