Product Overview
The BMM 20cc cycloidal hydraulic motor is a compact, high-speed unit with a geometric displacement of 19.9 ml/r (approx. 20cc). As part of the BMM/OMM series, it features a small, streamlined structure and excellent high-speed performance, serving as a reliable replacement for Danfoss OMM and Eaton J series micro motors. Fitted with a cylindrical mounting flange and 16mm output shaft, it is specially engineered for auxiliary drive systems in light agricultural machinery such as fruit harvesters, delivering stable and efficient hydraulic power for various small-scale equipment.
Core Features
Tailored for Light Agricultural Machinery (Fruit Harvesters)
19.9 ml/r displacement delivers a balanced 25 N・m continuous torque, perfectly meeting the power demands of auxiliary drives like harvester conveyors and vibration mechanisms. With a maximum continuous speed of 1000 rpm, it ensures quick equipment response. Weighing only 2.1 kg, its lightweight design minimizes complete machine weight load and simplifies installation.
Miniature Compact Cycloidal Technology
As part of the BMM micro series, it features ultra-compact dimensions ideal for space-limited installations. The integrated shaft oil distribution & output shaft design boosts oil distribution accuracy and volumetric efficiency. It operates stably under medium-to-high pressure, ensuring reliable performance during agricultural field operations.
Robust Load-Bearing Structure
Dual-end rolling bearings provide light lateral load capacity to withstand forces from pulleys or sprockets. The high-strength cast iron housing resists vibrations and minor impacts, ensuring durable operation in agricultural working environments.
