Applications in Hydraulic Systems<\/h3>\n

The Borelli Complete Chain Couplings – 12800 Series are essential mechanical components designed for safe and efficient power transmission within hydraulic systems and installations. Each complete coupling consists of precisely engineered components designed to work together, ensuring the effective transmission of substantial torsional loads. Each unit specifically includes a power unit coupling half, a flange-side coupling half, a high-strength transmission chain, a connecting link and a protective guard. This configuration ensures uniform force distribution during operation at a rotational speed of 2500 rpm.<\/p>\n

Construction Features and Material Treatments<\/h3>\n

The strength and reliability of the Borelli Complete Chain Couplings – 12800 Series result from the manufacturer’s careful selection of materials. The coupling halves, bars and chains are manufactured from UNI 16CrNi4\/Pb steel. To ensure optimal long-term performance, this steel undergoes a specific heat treatment that increases fatigue resistance and wear resistance. In addition, for applications requiring superior mechanical properties, certain coupling half variants are manufactured from quenched and tempered UNI 38NiCrMo4\/Pb steel. These special components undergo an additional surface nitriding treatment (Tenifer process), achieving a specified mechanical strength (R) ranging from 95 to 105 kg\/mm\u00b2.<\/p>\n

Technical Specifications, Dimensions and Transmission Capacity<\/h3>\n

The 12800 Series offers several sizes to accommodate different installation and power requirements, covering product codes from 12801 to 12808. Dimensions vary depending on the model: the external diameter (D) of the protective guard ranges from 101 mm for the most compact versions to 162 mm for the largest models. The overall length (L) ranges from 48 mm to 66 mm, facilitating installation in confined spaces. Regarding transmission performance, at a rotational speed of 2500 rpm, the couplings provide a maximum torque ranging from 15 kgm (equivalent to 52 HP) for model 12801 to 40 kgm (equivalent to 135 HP) for models 12807 and 12808. All kits include the external protective guard and connecting link for complete and safe installation.<\/p>\n
