Introduction and Series<\/h3>\n

The STAUFF Cover Plate LBBU-DP<\/strong> is a fundamental component for the secure installation and fastening of pipework and components in hydraulic circuits. Belonging to the renowned LBBU Light Series, this component is designed to ensure mechanical stability in standard applications, providing a robust upper support surface that evenly distributes the clamping force applied by the bolts.<\/p>\n

Construction Features and Materials<\/h3>\n

In terms of materials, the plate is manufactured from high-quality carbon steel, identified by material code W3. The distinctive feature of this version is its zinc\/nickel-plated surface treatment, which provides superior protection against corrosive agents typically encountered in industrial and hydraulic environments. The plate thickness, indicated by dimension “S” in the technical drawings, is precisely set at 3 mm for all dimensional groups included in the catalogue, ensuring the right balance between compact dimensions and structural strength.<\/p>\n

Dimensional Groups and Compatibility<\/h3>\n

The range is designed for use with multiple sizes, specifically STAUFF Groups 1 to 3 and the corresponding 1D, 2D and 3D versions. The geometric dimensions vary according to the group: for example, the overall length (L1) ranges from 35 mm for Group 1 up to 47 mm for Group 3D, while the width (B) remains constant at 30 mm, ensuring a perfect fit with the corresponding clamp systems. The plate features holes (D = 9 mm) suitable for accommodating threaded fastening elements. The standard configuration (thread code M8\/U5\/16) is designed to accommodate either ISO Metric M8 bolts or Unified Coarse 5\/16-18 UNC bolts.<\/p>\n

Connection and Mounting Components<\/h3>\n

Optimum fastening of the STAUFF Cover Plate LBBU-DP requires the use of Type AS Hexagon Head Bolts, compliant with DIN 931 \/ 933 or ANSI \/ ASME B18.2.1 standards. The system is compatible with different mounting methods: mounting with a Type LBBU-SP Weld Plate, rail mounting using SM-2-5D hexagon rail nuts, or direct panel mounting (without a weld plate). Upon request, alternative sizes for M6 and 1\/4-20 UNC bolts are available, as well as different surface finishes for special applications.<\/p>\n

Mounting Types and Bolt Variants<\/h3>\n

Correct installation of the plate depends directly on the selected base system. For applications using the LBBU-SP Weld Plate or SM-2-5D rail nuts, the lengths of the hexagon head bolts (L) vary according to the group (from 25 mm up to 45 mm for standard metric threads). If direct panel mounting (PM) is selected, without the use of the lower weld plate or rail nut, the required bolts have different lengths, ranging from 30 mm up to 50 mm, to compensate for the different installation dimensions. This combination versatility makes the STAUFF Cover Plate LBBU-DP a flexible and extremely reliable solution for managing hydraulic anchoring systems.<\/p>\n
