Product Description

The ZAL Precision Series right-angle housing, square mounting flange, with caged precision class helical planetary gears, in sizes through 220 mm. High torque capacity, quiet operation and backlash as low as <5 arcmin. The square output flange makes it particularly easy to install and save spaces for a wide range of applications. ZAF series gearhead overall design suitable for combination operation with servo motor high-speed input and achieves maximum torque output. Precision gear design and gear processing create a planetary gearhead with low backlash operation, high efficiency, low noise and long service life performances.

Key Features

  • Helical gear transmission with carburizing and quenching treatment, along with tooth profile modifications, ensuring quiet operation and smooth performance. The load-bearing capacity is 20% greater than that of straight-cut gears.
  • A monolithic output shaft with bearing support at both ends of the planetary gears, ensuring high precision and structural strength.
  • Minimal backlash, with a precision single-stage design achieving less than 5 arc minutes of backlash.
