The STAUFF Safety Locking Plates (Type SIG – Standard Series)<\/strong> are a fundamental component for the construction of stable and secure hydraulic systems. Designed to meet the rigorous technical specifications of DIN 3015, Part 1, these plates complement the pipe fastening system, ensuring precise alignment and consistent mechanical strength even under demanding operating conditions.<\/p>\n

Operating Principle<\/h3>\n

The primary function of the Type SIG safety locking plate is to interface with the Type AF stacking bolt. This combined system enables the creation of a modular structure in which the fastening elements work together as a single unit, reducing vibrations transmitted through the pipework. The use of this component prevents accidental bolt misalignment and ensures continuous fastening, a critical factor in preventing premature component failure or leaks within the hydraulic circuit.<\/p>\n

Construction Features and Materials<\/h3>\n

The versatility of the SIG Standard Series is ensured by the availability of different material variants, which can be selected according to specific environmental and corrosion-resistance requirements:<\/p>\n

    \n
  • W3 (Carbon steel, zinc\/nickel-plated):<\/strong> Ideal for standard applications in non-aggressive environments.<\/li>\n
  • W4 (V2A stainless steel):<\/strong> Material 1.4301\/1.4305 (AISI 304\/303), recommended for applications requiring increased corrosion resistance.<\/li>\n
  • W5 (V4A stainless steel):<\/strong> Material 1.4401\/1.4571 (AISI 316\/316 Ti), suitable for use in marine environments or in contact with chemically aggressive fluids.<\/li>\n<\/ul>\n

    The entire range is engineered to maintain the dimensional tolerances defined by DIN 3015, ensuring interchangeability with other components from the same STAUFF series.<\/p>\n

    Applications and Sectors<\/h3>\n

    Type SIG safety locking plates are used across all sectors of industrial and mobile hydraulics. Thanks to their compliance with the relevant standard, they are used in systems where vibration management and the mechanical stability of pipework are essential requirements. The “Standard Series” configuration covers STAUFF Groups 1 to 8, allowing a wide range of tube diameters to be accommodated while always ensuring uniform distribution of mechanical loads.<\/p>\n

    Technical Specifications<\/h3>\n

    The compact design and dimensional precision allow rapid installation, reducing machine downtime during maintenance or the assembly of new systems. Compatibility with AF bolts, also available with metric (M) or UNC (U) threads, completes the fastening system and provides an integrated logistics solution for purchasing managers and design engineers.<\/p>\n
