BOOSTER is a high-performance, low-backlash planetary gearbox. It was specifically designed for high-precision printing machines where very low-backlash is key, and laser-cutting machines, who require stiffness and high acceleration capacity.

The planet carrier is a cage, to provide stiffness and acceleration capacity. It is monobloc with the output shaft.
The cage is centered into the inner planetary ring by means of 2 high-precision, angular-contact ball-bearings.
This construction improves acceleration capacity and acceptance of important torque variations.
The planetary ring is monobloc with the housing and the output flange), to provide maximum rigidity to fast-reversals applications.
We recommend this line for applications using application factor Ka<1.85 (refer to the information section for more details about application factors). For greater application factors we recommend using a rotating output flange, as in the Ultimate line.
The servomotor shaft connection is a balanced coupling, so the efforts on your motor bearings are minimal.
Installation is fast and easy thanks to a 1-screw lock to your motor shaft.
The gearhead will be delivered with the adapting flange corresponding to your motor, at no extra-cost.
Quiet operationThe BOOSTER line follows the PerfectPitchTM concept, including the use of helical teeth to provide a quiet operation to your servomotor application.
High-precision planet gears in carburized and quenched steel allow high torque density and strong accelerations, year after year, without loss of precision.
The planet carrier is a cage, to increase torsional stiffness.
It is strongly supported by 2 preloaded angular-contact ball-bearings (small sizes) or taperred rollers bearings, to ensure the perfect alignment of the gears, even at maximum torque, as well as high acceptance of radial and axial loads.
High torsional stiffness
The planetary ring is monobloc with the external housing and the output flange, to provide high rigidity to your fast-reversals applications.
SAFETY FOR YOUR SERVOMOTOR BEARINGS
The Booster range features a standard, balanced coupling with a press-fitted pinion, to limit radial efforts on your servomotor shaft. xx

Following the ISO 6336-2 standard, for a 20,000 hours life with a 1,25 application factor, at nominal speed with 60°C internal temperature. Applying a lower torque prolounges life significantly.
Following ISO 6336-2 standard, for 2,000h (10% of life) with a 1,4 safety factor, at nominal speed with 60°C internal temperature. Using a torque higher than the nominal torque wears the internal gears.
1,000 occurences maximum
Speed at which nominal torque can be applied for 20,000 hours
Acceptable for a short duration only
Applied at the middle of the output shaft with a 100 rpm speed.
Measured with a 60°C gearbox using nominal speed and torque. Refer to temperature factors in dedicated section.
Minimum life at nominal speed and torque. Using lower speed and/or torque prolounges life significantly.
At nominal speed, measured at 1m.
