Product Details

DIN 9021 ISO 7093-1 Plain Washers - Large Series

Characteristics:

  1. Large Size Design: DIN 9021 plain washers from the large series come with a wide range of sizes, suitable for applications requiring a larger contact area.
  2. Flat Structure: The washers feature a flat surface, ensuring even contact and stable support when installed, effectively distributing pressure.
  3. Material Diversity: These washers are available in various materials, such as carbon steel and stainless steel, to adapt to different working environments and load requirements.
  4. Standardized Design: Conforming to the DIN 9021 standard, the washers' dimensions, shapes, and performance meet internationally recognized standards.

Advantages:

  1. Enhanced Stability: The large-series plain washers provide a larger contact area, increasing the stability of the connections and preventing loosening and vibrations.
  2. Reduced Pressure Concentration: The flat structure of the washers distributes the pressure on the connections, reducing pressure concentration and extending the service life of the components.
  3. Easy Installation: These washers can be placed easily between connecting parts, requiring no complex installation process or special tools.
  4. Strong Adaptability: Due to the material diversity, DIN 9021 plain washers can adapt to different working environments and load conditions, offering broad applicability.

Applications:

  1. Heavy-duty Equipment and Structures: In heavy-duty equipment, bridges, buildings, and other large structures, DIN 9021 plain washers enhance the stability and safety of the connections.
  2. High-load Applications: In applications that require enduring high loads, such as mechanical transmission systems and engines, these washers distribute pressure, reducing wear and failures.
  3. Vibration and Impact Environments: For equipment operating in vibrating and impacting environments, such as vibrating screens and crushers, DIN 9021 plain washers minimize the effects on connections, improving the stability and reliability of the equipment.
  4. High-precision Applications: In applications requiring high-precision positioning and stability, such as precision machine tools and measuring instruments, these washers provide stable support and positioning, ensuring accuracy and reliability.
