The STAUFF Bushing LBBU-HUE, belonging to the Light Series, provides a highly reliable technical solution for secure fastening in industrial hydraulic systems. This component is specifically designed for optimum compatibility with ISO Metric M8 or UNC 5/16-18 threads. It offers high installation versatility thanks to three different mounting configurations: installation with weld plate (SP), rail mounting with hexagon nut (SM) and panel mounting (PM), ensuring full compatibility with size groups from 1 to 3D.
The available product codes are: LBBU-HUE-1/1D-SP-M8/U5/16-W3, LBBU-HUE-1/1D-SM-M8/U5/16-W3, LBBU-HUE-1/1D-PM-M8/U5/16-W3, LBBU-HUE-2/2D-SP-M8/U5/16-W3, LBBU-HUE-2/2D-SM-M8/U5/16-W3, LBBU-HUE-2/2D-PM-M8/U5/16-W3, LBBU-HUE-3/3D-SP-M8/U5/16-W3, LBBU-HUE-3/3D-SM-M8/U5/16-W3, LBBU-HUE-3/3D-PM-M8/U5/16-W3.
The STAUFF Bushing LBBU-HUE is an essential component within the Light Series fastening range for hydraulic systems. Its structural purpose is to provide an extremely rigid and secure mounting point for pipe clamps in a wide variety of industrial hydraulic applications. The mechanical interface provided by this bushing enables the correct absorption of dynamic loads and vibrations transmitted along pressurised pipework, maintaining the stability of the entire line. The flexibility of the STAUFF system allows technicians to implement complex layouts while maintaining the required safety standards.
The engineering of this component allows it to adapt to different installation scenarios, divided into three main mounting types. The variant identified by the code SP is designed exclusively for integration with the Type LBBU-SP Weld Plate. For configurations using existing mounting rails, the rail-mounted version with hexagon nut is available, identified by the code SM (compatible with Hexagon Rail Nut SM-2-5D). Finally, for system architectures requiring direct fastening, the PM option enables panel mounting without the use of weld plates or rail nuts.
The technical specifications of the component fully cover STAUFF size groups 1 to 3 and the corresponding variants 1D to 3D. All models share fixed transverse dimensions, featuring a larger diameter (D1) of 12 mm and a smaller diameter (D2) of 9 mm. The longitudinal dimension (L) varies according to the size group and mounting type, ranging from 12.8 mm for Group 1 SM mounting models up to 38.8 mm for Group 3 panel mounting (PM) configurations. The design incorporates precision internal threads, standardised for ISO Metric M8 and Unified Coarse Thread 5/16-18 UNC. The materials used, identified by code W3, are ideally suited for use with weld plates manufactured from phosphated carbon steel. To meet specific technical requirements, alternative thread sizes such as M6 and 1/4-20 UNC, as well as different surface treatments, are available upon request.
Correct interpretation of the order codes is essential for selecting the appropriate component. The STAUFF alphanumeric structure, for example LBBU-HUE-2/2D-SP-M8/U5/16-W3, defines in sequence: the Light Series family (LBBU), the bushing component type (HUE), the size group (2/2D), the mounting type (SP, i.e. weld plate), the Metric or UNC thread option (M8/U5/16) and the material identifier (W3). Accurate code selection ensures full mechanical compatibility with STAUFF system plates and nuts, optimising installation times and eliminating the risk of accidental loosening in hydraulic circuits.
