HDO Series

Helical Bevel Heavy Duty Gear Units

When high output torque, robustness reliability and long operating life must be achieved, Bonfiglioli’s HDx Series represent the best solution for our custmers needs. Thanks to high quality materials and an optimized design, HD Series can operate in the harshest environemt, as well as in explosive atmospheres, with low maintenance costs and long time service intervals. The output shaft can be chosen both in the parallel (HDP) or right angle(HDO) configuration and to always ensure the minimization of mounting space. HDx Series, furthermore, can be deeply customized thanks to an extremely wide options and accessories portfolio, thus matching most of the requirements of a large applications number.
