• Description

  • Kian Tajhiz RPS-series is a specialized planetary reducer series which offers a high load and a high reduction of the gear ratio. It is the best reducer for an application with complex specifications and it is evaluated as a premium product that reflects the requirements of our customers.


  • Features
    • Compact and light-weight

      Power distribution due to various planetary gears and compact casing due to a concentric shaft make the product small, light-weight, and easy to install in small spaces.

    • Dual-lip type oil seal prevents oil leakage

      Maximized efficiency and minimized noise lowers the inertia moment, while the modification of the teeth of a gear to an ideal shape via carburizing heat treatment, gear grinding, and optimum internal part design offers high efficiency and low noise.

    • High reduction of gear ratio

      A planetary gear enables a high gear reduction ratio of over 1,000,000:1 and the computerized design guarantees high reliability.

    • Module system

      A module system is adapted to all parts for quick production and supply.

    • Technical agreement

      A technical agreement with RENK in Germany has been concluded to meet the technical requirements of our customers.
