Three planetary gearheads with output shaft on a transparent background

Planetary gearheads - output shaft

The planetary gearboxes with output shaft have a precision gear design and a professional gear processing that create a low backlash operation, high efficiency, smooth running low noise and long life of the planetary gearbox.  BJ-Gear offers both premium types and precision types. 

The planetary gearboxes offered by BJ-Gear have a helical gear design that enhances the tooth engagement rate of 30% or more. The special helix design reduces the axial thrust and allows high-speed servo motor input as well as maximum torque output. The precision gear design and professional gear processing create a low backlash operation, high efficiency, smooth running, low noise and long life of the planetary gearboxes. 

BJ-Gear offers both premium types and precision types. Premium type: PHL, PGH, PUL. Precision type: PGLH.
