8G premium planetary gearbox
Lowest backlash – highest loads
These gearboxes feature very low backlash and high torsional rigidity. They are especially well suited for use in handling systems that run with high speeds and acceleration values and applications in which the optionally available backlash of <1 arcminute is of particular significance.
The honed gearing of this series ensures the lowest level of operating noise and reduces vibration. The use of special bearings enables high radial and axial forces. These gearboxes are the right choice for both S1 and S5 operation. The series also features IP65 protection, flexible mounting orientation and maintenance-free operation through permanent lubrication. The premium 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 planetary 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.
