Construction Features and Materials<\/h3>\n

The STAUFF Weld Plate LBBU-SP<\/strong> is part of the Light Series (Light Series LBBU) dedicated to fastening systems for pipes and hydraulic components. The standard construction material, identified by code W2, is phosphated carbon steel. This material configuration ensures high mechanical strength and provides a suitable base for structural welding operations. Alternative materials and surface finishes are available upon specific request to meet special application requirements.<\/p>\n

Dimensional Specifications<\/h3>\n

The range covers STAUFF Groups 1 to 3 and 1D to 3D, providing precise dimensional scalability. The plate width (dimension B) remains constant at 14 mm (0.55 in) for all groups, as does the height (dimension H) at 5 mm (0.20 in). The overall length (dimension L1) varies according to the group: from 34 mm (1.34 in) for Group 1 up to 86 mm (3.39 in) for Group 3D. The centre distance (dimension L2) is 20 mm for Groups 1, 2, 10, 1D and 2D, while it increases to 30 mm for Groups 3 and 3D.<\/p>\n

Thread Systems<\/h3>\n

Each STAUFF Weld Plate LBBU-SP is equipped with threaded elements for securing the clamps. Standard catalogue options include ISO Metric M8 thread (code M8) and Unified Coarse 5\/16-18 UNC thread (code U5\/16). The product design also allows alternative thread sizes, such as M6 and 1\/4-20 UNC, to be integrated upon request in order to meet specific design requirements.<\/p>\n

Mounting Variants and LBBU-HUE Bushings<\/h3>\n

The weld plate mounting system (Type of Mounting SP) operates in conjunction with LBBU-HUE Series bushings. These bushings feature standardised outside diameters (\u00d8D1 equal to 9 mm and \u00d8D2 equal to 12 mm) and variable lengths L ranging from 13.5 mm up to 38.8 mm depending on the group and mounting type. In addition to standard weld plate mounting (SP), LBBU-HUE bushings can be integrated with Hexagon Rail Nuts (Hexagon Rail Nut SM-1-5D – SM mounting) or used for direct panel installation without a plate (PM mounting).<\/p>\n

Product Coding System<\/h3>\n

The standard order code follows a strict logical structure: the prefix “LBBU-SP” identifies the Light Series weld plate; the following field indicates the STAUFF Group (e.g. 1, 2, 3, 10, 1D, 2D, 3D); this is followed by the thread designation (M8 or U5\/16) and finally the material code (W2 for phosphated carbon steel).<\/p>\n
