Planetary Gearboxes

SBR Series Right-Angle Planetary Gearboxes

The SBR Series combines a planetary reduction stage with a right-angle bevel output box, enabling compact 90° power transmission for space-constrained machine layouts. Each unit integrates output bevel gear, right-angle box, input bevel gear, locking device, and input coupling into a single assembly.

Available in frame sizes 060, 090, 115, 142, 180, and 220 with single-stage ratios from 3:1 to 20:1 and two-stage ratios from 25:1 to 200:1. Rated output torque ranges from 90 Nm (060SBR at 3:1) to 2,000 Nm (220SBR at 3:1).
