3000 Standard Specifications

er_standardThe Circulute 3000 (ER) series is the ideal choice when requiring a robust gearbox in a compact package. The cycloidal design provides a large amount of contact surface area between the wheel and the pins that allows it to handle unstable loads well and minimize wear. This is our standard cycloidal series providing a variety of frame sizes (A – F) that can handle a maximum input of 60 HP, and also the possibility to implement multiple reductions when required.

There are a number of mounting options available, such as the following;

Input Mounting Configurations:
