8G standard planetary gearbox

8GP Planetengetriebe_WEISS

The cost-effective alternative to the premium series

Standard series planetary gearboxes are the ideal solution for applications that don't require an extremely low level of backlash or IP65 protection. Typical applications for these gearboxes include those with high speeds and acceleration values as well as toothed belt or rack applications.

In combination with honed sun and planets, the straight-toothed and fully hardened gearing guarantee high output torque and high-precision positioning. The unique building block principle used with this series makes it possible to handle all output geometries established on the market in the area of coaxial planetary gearboxes. The standard series gearboxes are available as angular planetary gearboxes, planetary gearboxes with output flange and coaxial planetary gearboxes.

One-of-a-kind building block principle for standard gearboxes

The standard gearboxes are single-stage for gear ratios i= 3, 4, 5, 7, 8 and 10 and have ≤8 - ≤15 arcmin backlash. In addition, these gearboxes are also offered in two-stage or three-stage designs. At the top of the product line, the premium series provides backlash ≤ 1 arcmin as an option paired with high output torques. B&R gearboxes from the standard series give you the possibility to choose between all output geometries established on the market in the area of coaxial planetary gearboxes.

  • This enables B&R to supply gearboxes for existing applications without having to make changes to the machine.

With the 8GP55 series, you are also able to combine the output bearings and the output geometry of the 8GP60 premium series in combination with the torsional play of the standard series for applications that do not require extremely reduced backlash. This makes it possible to handle high radial and axial forces in a cost-efficient manner.

  • In applications where the backlash of the standard series is sufficient, this offers a cost-optimized solution for implementing higher bearing forces.
