Hollow shaft angular gearbox

Cable feed-through and output shaft flanges on both ends

12/11/2013


B&R's selection of premium-grade angular planetary gearboxes has been expanded to include the new 8GA75 model for flange sizes 60 mm to 142 mm. The hollow shaft differentiates these new gearboxes from the well-known 8GA60 series with a solid shaft. With a hollow shaft it is possible to feed cables, fluid lines and material strands through the drive axis. The hollow and solid shaft models have identical performance data and dimensions.

Easy to create a symmetrical load distribution

The gearboxes are also available with output shaft flanges on both ends. This opens up additional design possibilities, such as drives with symmetrical load distribution for conveyor applications. It is also easier to connect external encoders to provide high-precision position measurements for controlling braking systems. The gearboxes are also optionally available with only one output side.

Like all premium gearboxes from BR, the 8GA75 hollow shaft gearbox features exceptionally low backlash and high torsional rigidity. This permits high positioning precision in highly dynamic servo applications. Upon request, B&R can deliver these gearboxes with a servo motor preinstalled.
