Limit Lost Motion with Gam’s New SPH Flange Planetary Gearbox

The compact SPH-F gearbox can be used when space is limited and the ISO 9409 compatible output flange allows for easy mounting of machine elements such as pinions, pulleys, or other adapters.

Greenville, DE — Backlash and Torsional Rigidity are both important values to consider when selecting a high precision gearbox as they both affect lost motion (arcmin). GAM's SPH Flange Gearbox has a single piece steel housing and ring gear machined directly inside for maximum stiffness. The helical gears are precision cut and ground for extremely quiet and smooth torque transmission with a standard backlash rating of < 3 arc-min or < 1 arc-min reduced.


The compact SPH-F gearbox can be used when space is limited and the ISO 9409 compatible output flange allows for easy mounting of machine elements such as pinions, pulleys, or other adapters. To accommodate direct connection to machines, the SPH-F has strong taper roller bearings set at a wide distance and a fully supported planet carrier for high load carrying capacity. The ring gear is machined directly into a single piece steel housing for improved torsional rigidity. Currently offered in three frame sizes, the SPH-F is rated for up to 450Nm nominal and 675Nm acceleration torque in the largest size.

Gam SPH-F Flange Planetary Gearbox features:
• Low Backlash: <3 arcmin standard for single stage units, <1 arcmin reduced backlash
• Smooth and quiet torque transmission
• High load carrying capability
• High torsional rigidity

FAULHABER MICROMO - Impressive accuracy through the latest chip technology

With the launch of the IEP3, FAULHABER expands its product line with an incremental encoder which, thanks to the latest chip technology, achieves a very high resolution and accuracy. With a diameter of just 8 mm, the IEP3 is very lightweight and compact yet still offers a resolution of up to 10,000 lines per revolution - made possible by the latest chip technology with high interpolation. In the standard version, the resolution is freely programmable from 1 - 4,096 lines per revolution. Moreover, the chip technology that is used ensures a high positional accuracy of typically 0.3 °m as well as a high repeatability of typically 0.05 °m thanks to accuracy compensation.
