The A series gearboxes are equipped with aluminium housing and are available coupled to standard B5 flange motors. The basic standard version foresees the output shaft hollow type, for a possible self-adapative cantilever installation with simple reaction arm. Thanks to their modular design , a lot of technical solutions are possible, differently combined: single or double solid output shaft, B5 output flange, installation on feet fixed to the housing. The reduction ratios , at 2 or 3 steps according to the different versions , are made with Gleason type bevel gears and with cylindrical gears with helical teeth, ground or shaved, designed according to the ISO 6336 standards. Input shaft or just coupling flange versions, without motors, are possible.The input power goes up to 5.5 kW and the output torque goes up to 410 Nm , according to the different sizes
