Gear couplings/Elastic couplings
The full-flex gear couplings manufactured by MAINA S.p.A. are employed to mechanically connect two rotating shaft which have to transmit a torque, in a torsionally rigid way. The torque is transmitted from hub to sleeve and viceversa, by the working gear teeth and between the connecting flanges of the two hubs by calibrated bolts.
The gear couplings are flexible to compensate the misalignment of the shafts to be connected, this is possible by engaging outer spherical teeth with inner cylindrical ones, both having proper tangential clearance. The standard gear coupling are manufactured in AISI 1045, and upon request, is possible to have also nitroxidation treatment. We keep the gear coupling ready in our warehouse, so we can deliver in few days and at a very competitive prices.
Gear coupling line: GO-A, GO-AMM, GO-FA, GO-FAM.
The gear couplings series GO-A are complete with tubular spacer manufactured in the same material of the gear coupling and are employed to transmit a torque when there is distance between the two shafts; are available with Ls from 107mm. up to Ls > 2500mm. Is also possible to perform dynamic balancing, for rotations above 400 rpm. We always suggest dynamic balancing also on tubular spacers having length above 600mm.
Gear coupling with tubular spacer line: AO-A, AO-AMM.
The gear couplings for hoist system series GTS are employed in the raising plants, cranes, hoists etc. Due to their strong execution they can guarantee a high safety to the hoist plants and respect to all the relevant normatives, further to guarantee a longer working life during the years, compared to the competitors models.
Gear coupling for hoist plants line: GTS.
The couplings FEMA-TYRE are used where it is required to recover a high angular misalignment is one of the most interesting characteristics of couplings FEMA-TYRE is the easy way in which fastens the elastic part. The tire is mounted on the hubs and fastened by means of Crown (2) and screws. There is no need for perfect adjustment of the unit you are connecting and can easily overlook the small movements of their axles. Can be supplied with ATEX certificate.
Flexible gear line: FT, FT-DVA.
Protection structure for “twirling”, torsion, impact and abrasion. Easy to replace and maintaine, no need for oil or grease, it is simple to replace without separation of the motor shafts or connector on the related line, thanks to its simple structure. There is a possibility for different connection and assembly with the same hub. With elastic element in polyurethane for the excellent chemical resistance. Maximum elasticity in running and with low noise.
Elastic coupling line: HS, HT.
FEMAFLEX couplings are flexible couplings couplings with insert in polyurethane axially split to be replaceable without requiring the disassembly of the hubs. The couplings are also available with conics fitting bushings and spacer. Maximum transmittable power is of 40.000 Nm in continuous with allowing shafts with a maximum diameter of 210mm.
Elastic coupling line: FF, FF-S.

In addiction to the hydraulic motors FEMA offers a wide range of axial piston motors in alternative to the most common brand. The series starts from a displacement of 12cm³ up to a130cm³.
We offer a very good quality with a fast delivery time.
Axial Piston Motor line: M-ISO.
Made up by 2 relief valves with crossed tank, this valve is used to block pressure to a certain setting in the 2 ports of an actuator/hydraulic motor.
It’s ideal to provide protection against sudden shock pressures and to adjust different pressures in the 2 ports of an hydraulic circuit as well. Direct flange is ideal for Danfoss motors type MS, MP & MR, MT & MV and provides a maximum safety, very low pressure drops and solid installation.
Gear boxes
These wheel reduction gears cover the ranges from 100 up to 3600 daNm. They are especially studied for the movement of the tracked vehicles, (tractors, excavators, drilling machines etc.) where is required a stationary hydraulic brake, negative type. They further offer also compact coupling solutions with axial piston motors and with semi-integrated orbital motors.
This planetary reduction gears line is the main production line with wide choice of reduction ratios and output torques. They have several output option such as male shaft or female shafts splined type and with input conical torque and several rotation supports. Infinite modular possibilities allows infi nite solutions on all the machines in the different industry sectors.
Planetary Reduction Gears line: INDUSTRIAL
These hydraulic brakes, negative type, are very important in applications where is required, for safety reasons, an emergency brake: self-propelled cranes, machines for road construction, winches, etc. They are available in a modular version for application on reduction gears and a direct version for application on hydraulic orbital motors.
