Series N3: 3-Stage Planetary Gearbox
Our team’s 3-stage gearboxes for planetary applications (N3 series) are available in many low-speed shaft designs, including the cylindrical shaft fitted with a key or spline shaft hollow shaft that has a shrink disc or splined shaft.
Each three-stage planetary gearbox features an output bearing with a large capacity. This is why all of our 3-stage planetary gearboxes have high capacities in radial and axial dimensions. Additionally, they are resistant to the effects of overturning and increase the reliability of gearboxes and their efficiency.
To be a high-quality producer of planetary gearboxes; the tooth profiles of our planetary gearboxes 3 stages are precisely crafted for quiet noise operation.
If you require feet, flanges, or mount solutions we’ll make them to meet your requirements. Also, each part of the gearbox is subject to a rigorous quality control process prior to shipment.
Through the Planetary Gear Calculator, you can select from a range of outputs for speed and torque. The 3-stage planetary gearboxes we offer are designed to be modular and easily customizable.
Additionally, the 3-stage planetary gearbox comes with extremely stable and sturdy support. This guarantees high torsional stiffness for every gearbox.
