g7x0/g8x0 planetary and bevel-planetary gearboxes 2–1800 N·m

Technical specifications

Specifications are taken from the manufacturer’s technical documentation. Updated 11/06/2026.

Description

The g7x0 series offers good price for performance and a full set with servo motors, while the g8x0 has the highest accuracy, and its low backlash can be reduced even further to order. The torques are g7x0-P 4–800 N·m, g8x0-P 27–1800 N·m, g7x0-B 2–260 N·m, g8x0-B 21–610 N·m. Lubrication is filled for the whole service life, so the gearbox is mounted in any position. The output shaft can be flanged, solid or hollow. For universal applications there are IP65 variants. In combination with the MCS the P types have 0.25–15.8 kW and 1–1700 N·m, with the MCA 0.8–20.3 kW and 5–1650 N·m, with the m850 0.11–9.2 kW and 5–1800 N·m. The B types with the MCS have 0.25–10 kW and 2–530 N·m, with the MCA 0.8–6.9 kW and 7–420 N·m, with the m850 0.11–9.2 kW and 4.5–800 N·m, and the g7x0 with the SDSGA 0.075–0.6 kW.

How to choose

Type P is chosen when the drive is in line with the axis, type B when an angular layout is needed. Accuracy decides between the series, because the g8x0 holds the lowest backlash, while the g7x0 is more economical. If torques above 1800 N·m or dimensions with a market-standard shaft are needed, look at the g500-B of 6–20 000 N·m. For servo geared motors with a helical gearbox of 0.25–20.3 kW there is the g500 with MCS, MCA and m850.
