GB849/GB850 standard ball/taper washers are a type of fastener used for bolts or screws and are mainly used to provide uniform load distribution and to prevent the head of the screw or nut from pressing through the material being joined. These washers are usually made of carbon steel, stainless steel or other non-ferrous metals and can be available in different surface finishes such as galvanized, nickel-plated or cadmium-plated for improved corrosion resistance and aesthetics.
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:
Automatic Adjustment: Ball washers automatically adjust to compensate for misalignment, avoiding bolt bending and reducing bolt fatigue. Equal distribution of surface pressure: Designed to use high grade alloy steel for increased reliability, the equal distribution of surface pressure increases the clamping length, which in turn increases the likelihood of the bolt stretching. No Countersinking: The washers are designed to be easily machined into thinner washers without the need for additional machining of the orifice flats. Corrosion resistance: Ball/taper washers, especially made of stainless steel, have excellent corrosion resistance and are suitable for outdoor or wet environments.
Scope of Application
Construction industry: In construction and civil engineering, ball/taper washers are used to connect beams, columns and other structural components, providing a stable and reliable connection. Machinery and equipment manufacturing: In machinery and equipment manufacturing, they are used to secure and adjust machine parts such as bearings, gears and motors. Chemical industry: In chemical plant construction, these washers are used to connect and secure equipment such as pipes, pressure vessels and heat exchangers due to their good corrosion resistance. Automotive industry: In automotive manufacturing, spherical/tapered washers are used to connect automotive components such as chassis and body fixings.
