Overview of Planetary Gearbox

  • Quietly operation of VRB speed reducer thanks to the use of helical gears.
  • High precision positioning for backlash smaller than 3 arcs. min.
  • High rigidity and high toque of 3F VRB precision gearbox due to the use of integrated roller bearing.
  • It is convenient to install our servo gearbox on any brand of motor of any size.
  • The use of high-quality lubrication grease ensures free maintenance and no grease leakage.

Description of Precision Gearboxes

Our company uses the high technology of precision gears to manufacturing high-precision, high-rigidity planetary gearboxes for customers to meet the growing demand for high-precision applications.

From the smallest EPT042 model to the largest EPT220 model, you can choose from boards in a variety of frame sizes. In addition, we also offer one-stage planetary gearboxes with ratios from 3 to 10 and two-stage planetary gearboxes with ratios from 15 to 100.

Our replacement for EPT precision gearboxes All models are available in standard input and output dimensions. Additionally, we can provide you with custom services to meet your unique requirements. For the custom gearbox, we need to know your motor input size LR, LE, S, LB, LZ, and LA as shown in the picture below. If the output size of the reducer you need is non-standard, please provide the size you require.

EPT series in-line planetary gear reducers only provide two accuracy grades, P0 (≤2-4 arc.min) and P1 (≤4-6 arc.min). If you need a high precision helical gear reducer then our EPT is for you. Widely used in servo applications and automation applications, it is usually installed on servo motors and stepper motors to expand output torque while reducing speed. Many customers benefit from our high-quality planetary gearboxes.

Application of EPT Precision Inline Gearbox

The EPT series of high-precision planetary gearboxes are ideal for your servo and motion control applications. Widely used in papermaking equipment, solar energy equipment, polishing machine, CNC cutting machine, pipe bending machine, automobile equipment, reciprocating machine, engraving machine, glass equipment, woodworking machinery, injection molding machine, aluminum curtain door and window equipment, circuit board equipment, packaging equipment, Experimental equipment, coating machines, precision testing instruments, university research institutes, etc.
