B Series High Precision Speed Reducer & Torque Planetry Gearbox
Overview of B Planetary Gear Reducer
- The minimum backlash can reach 0-3 arcmin.
- With the advantages of high High torque and high strength.
- It can be applied to any servo motor and stepper motor.
- The positioning time of starting and stopping is shorter.
- High rigidity and high motor rotor inertia.
- Due to the miniaturization of motor power, it can achieve the stability of inertia load and small vibration.

Description of B High Precision Planetary Gearboxes
Our company’s famous B 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 Power-transtech’s famous B series planetary gearboxes, it is widely used in servo applications in the motion control industry. Our company’s famous B 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
Application of B High Precision Planetary Reducers:
Our company’s famous PAB high-precision planetary gearboxes are widely used in the aviation industry, aerospace, ships, radar, submarines, food machinery, medical machinery, women’s equipment machinery, and composite materials. equipment, precision testing instruments, data communication systems, robots, robotic arms, CNC machine tools, cutting and welding equipment, laser systems, textile machinery, printing and dyeing machinery, packaging machinery, printing machinery, testing machines, stamping technology, plastic machinery, glass machinery, starting Heavy machinery, metallurgical machinery, construction machinery, and university research institutes, etc.
