Indication of Model Numbers of EPB Speed Reducers


Description of EPB High Precision Planetary Gearboxes

Our company's famous EPB series high-precision planetary gearbox adopts the integrated design of planet carrier and output shaft to ensure maximum torque rigidity and stability. A variety of backlash types can be selected according to customer needs: micro precision backlash (P0), precision backlash (P1) and standard backlash (P2). Thanks to the high cost performance of 3F's famous EPB series planetary gearboxes, it is widely used in servo applications in the motion control industry. Our company's famous PEB precision gearbox has large torque and input diameter D4 can reach φ255mm, which greatly meets customer needs. Single-stage planetary gearboxes and two-stage gearboxes are available:

●First-level ratio: 3, 4, 5, 6, 7, 8, 9, 10

●Two-level ratio: 12, 15, 20, 25, 30, 35, 40, 50, 60, 70, 80, 90, 100
