Borelli Complete Chain Couplings – 16800 Series
The Borelli Complete Chain Couplings – 16800 Series ensure reliable power transmission, accommodating a maximum angular misalignment of 2° at a rotational speed of 1500 rpm. These components are manufactured from heat-treated UNI 16CrNi4/Pb steel, providing high resistance to mechanical stress. Certain models are manufactured from quenched and tempered UNI 38NiCrMo4/Pb steel with Tenifer nitriding treatment, achieving a mechanical strength of R = 95-105 kg/mm². The complete kit includes all the components required for safe and efficient installation in hydraulic systems.
The available product codes are: 16801, 16802, 16803, 16804, 16805, 16806, 16807, 16808, 16809, 16810, 16811, 16812, 16813, 16814, 16815, 16816, 16817, 16818, 16819, 16820, 16821, 16822, 16823, 16824, 16825.
The Borelli Complete Chain Couplings – 16800 Series provide a robust and technologically advanced solution for power transmission applications in hydraulic systems. The structural components, including splined coupling halves, splined bars and chain couplings, are manufactured from UNI 16CrNi4/Pb steel. This material undergoes specific heat treatments to optimize surface hardness and core toughness, preventing premature wear during continuous operating cycles.
For applications requiring even higher mechanical strength, the series includes coupling halves manufactured from quenched and tempered UNI 38NiCrMo4/Pb steel. These components undergo a nitriding process (Tenifer), a thermochemical treatment that significantly increases wear resistance and fatigue resistance, providing a mechanical strength ranging from R = 95 to 105 kg/mm². This selection of manufacturing materials allows the coupling to be adapted to the specific load requirements of the system.
The Borelli Complete Chain Couplings – 16800 Series are designed to maximize transmission efficiency. These components are rated to transmit their maximum torque at a rotational speed of 1500 rpm. A key technical feature is their ability to accommodate normal shaft misalignment: the couplings support a maximum angular misalignment of 2°, helping protect bearings and motor shafts from abnormal radial and bending loads that could compromise the integrity of the machinery.
Each unit in the 16800 Series is supplied as a complete assembly ready for installation. The standard configuration includes a splined coupling half, a motor coupling half, a transmission chain, a connecting link for secure chain closure and an external protective guard (housing). The extensive range of models, with power ratings from 0.37 HP to 132 HP and carefully scaled overall dimensions (diameter D and length L), ensures excellent adaptability and interchangeability across different motor-pump coupling configurations.
