PRECISION DRIVE
PVBF090 Right-Angle Hollow-Output Planetary Gearbox
A right-angle planetary gearbox with a keyed output bore and a 19-70-90 motor interface.
PVBF090 combines a 90-degree drive arrangement with a keyed output bore and a square output mounting flange. Drawings cover L1 and L2 with a Ø20 output bore, plus an L2 Ø18 output-bore version. Verify the Ø19 motor shaft, Ø70 pilot and Ø90 bolt circle, output bore, keyway and engagement depth. Torque and efficiency vary by configuration: at L2 ratio 100, the Ø20 version is rated 96 Nm and the Ø18 version 56 Nm. The Ø20 drawing identifies a thin keyway wall and requires signed drawing approval. Use the matching drawing for installation. The image is a PVBF series reference.
