PBE120 Hollow Output Planetary Gearbox
PBE120 has a 20 mm keyed output bore. The supplied drawings cover L1/L2 22-110-145 interfaces and an L1 24-95-115M6 variant.
PBE120 is an inline planetary gearbox with a keyed hollow output. Standard drawings show a 22-110-145 motor interface; a separate L1 version uses a 24-95-115 interface. Rated L1 output torque ranges from 86 to 211 N·m, depending on ratio. The alternative interface has separate dimensions and accuracy requirements, so use its own drawing for selection.
