Custom CNC Machined Stainless Steel Zinc Plated Tab Washer Locking Plate Heavy Duty Gear Tooth Transmission

Product details

Core Product Advantage: This custom locking plate uses a gear tooth outer profile that engages firmly into the housing slot, so the fitted nut cannot rotate back even under heavy vibration. The large hollow window structure keeps the plate light while the solid center disc grips the nut face securely.

Practical Function Design: The plate slides over the shaft and sits against the nut, while the outer teeth lock into the housing slot to stop rotation. Once fitted, it prevents loosening without extra adhesives or locking wire, making maintenance simpler.

Material And Specification Details: Commonly produced from carbon steel or 65Mn spring steel with a blackened phosphated surface for rust resistance, hardness and springiness. 304 stainless steel with blackening or black zinc plating is available for humid working conditions. Parts are laser cut or stamped per customer drawing, with dimensions and tooth layout confirmed before production.

Application Scenarios: Used on transmission shafts, clutch assemblies, gearboxes, motor rotors and drive trains where nuts must stay tight under vibration and shock. Also used on agricultural machinery, construction equipment and gear reducers. Gearbox makers, motor manufacturers, transmission repair shops and OEM assembly plants order these plates in custom shapes and quantities.

Packaging And Supply Support: Plates are packed in poly bags with inner boxes and export cartons, with anti rust paper between layers. Laser marking of logos and part numbers on request. Sample orders and bulk shipments are supported with flexible lead times based on volume. OEM and ODM customization of material, finish, tooth shape and dimensions is welcome, with technical guidance included.
