Case-Hardened and Tempered Planet Gears

The planet gears are made from carburized and quenched steel, providing:

long-term backlash stability,
increased wear resistance,
and the ability to withstand frequent accelerations and repetitive load profiles.

Forged-steel cage-type planet carrier

The planet carrier is a forged-steel cage, forming a monobloc assembly with the output shaft, which delivers:

unrivaled torsional stiffness for its category,
high mechanical reliability,
and reduced sensitivity to deformation under standard duty cycles.

Cantilevered output shaft support

The entire output stage operates in an overhung configuration, supported by two ball bearings at the gearbox output. This economical design is ideal for:

moderate radial loads,
low-dynamic applications,
machinery where extreme rigidity is not critical.

Especially suitable for:

applications with moderate radial and axial loads,
cost-efficient machines or standard duty cycles,
systems requiring 8 arc-minutes of backlash without the need for high rigidity,
projects where price is a key factor without sacrificing reliability.

Fast, Secure and Easy Connection

The motor-shaft interface uses a precision-balanced coupling, designed to minimize loads on the motor bearings and ensure smooth operation.
Installation is quick and intuitive thanks to a single-bolt clamping system on the motor shaft, providing a firm and reliable assembly.
Each gearbox is supplied with a motor-specific adapter flange, ready for immediate installation.

Performance highlights
