The GB855 and DIN463 standards deal with double lug stop washers (Double lug stop washer), which are washers with two projections (ears) used to hold a part in the axial direction, preventing it from moving in the hole.

Carbon Steel: Typically used for general applications.

Stainless Steel: For environments where corrosion resistance is required.

Alloy Steels: Used in applications requiring high strength or high temperature resistance.

Advantage:

DOUBLE EAR DESIGN: The two projections of the double ear stop washer provide extra friction and holding power, effectively preventing parts from loosening. EASY INSTALLATION: These washers are easy to install and remove without special tools for quick maintenance and replacement. CORROSION RESISTANCE: The material is usually spring steel, and the surface may be zinc plated or other surface treatments to improve corrosion resistance. Various materials: Different materials can be selected according to different application requirements, such as carbon steel, stainless steel, alloy steel, etc., to adapt to different working environments.

Scope of Application

Mechanical Manufacturing: In the field of mechanical manufacturing, it is used to fix rotating or sliding parts such as gears, bearings and bushings. Automotive industry: in the engine, gearbox, chassis and other key parts of automobiles to ensure the correct positioning and fixation of parts. Electrical equipment: In electrical equipment, used to keep electrical connectors and terminals in place and prevent loosening due to vibration. Aerospace: In aerospace, to ensure the precise installation and fixing of critical components to withstand extreme operating conditions.
