B&R’s selection of angular planetary gearboxes has been expanded to include the new 8GA75 model for flange sizes 60 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, the company says. The gearboxes are available with output shaft flanges on both ends. This opens up additional design possibilities, such as drives with symmetrical load distribution for conveyor applications, the company explains. The gearboxes are also available with only one output side.
