DIN 1481
DIN 1481 is a standard by the German Institute for Standardization (DIN) for slotted spring pins, also known as spring tension pins or roll pins. This standard defines the dimensions, tolerances, and mechanical properties of spring pins used for securing and positioning components in various mechanical and structural applications. DIN 1481 pins are available in different sizes and materials to meet a wide range of requirements.
Long Text:
DIN 1481 is a standard by the German Institute for Standardization (DIN) for slotted spring pins, also known as roll pins or spring sleeves. It defines the dimensions, tolerances, and mechanical properties of pins used to secure and align components in mechanical and structural systems. DIN 1481 pins are available in a variety of sizes and materials to suit different application needs.
Characteristics and Dimensions:
-
Available in various diameters (1 mm to 50 mm) and lengths (up to 150 mm)
-
Cylindrical shape with a longitudinal slot
-
The slot allows compression during insertion, providing a spring effect for secure fastening
Materials and Surface Treatments:
Common materials include:
-
Spring steel
-
Copper
Surface treatments may include:
-
Phosphating
-
Zinc plating
Applications:
-
Mechanical engineering: Fixing gears, levers, and components on shafts
-
Automotive industry: Securing parts in engines, transmissions, and suspensions
-
Electrical engineering: Holding components in electrical devices
-
Household appliances: Fastening moving parts in various devices
Installation and Use:
Proper size and material selection are essential. Use a dedicated tool (e.g., spring pin insertion tool) to ensure correct tension and placement.
Conclusion:
DIN 1481 spring pins are essential fasteners in many mechanical and structural applications. Their standardized design ensures secure and reliable connections in a wide range of uses.
