China Orbital Motor by ChangJia

Product Overview

1) Product overview

Product Features

- The China Orbital Motor by ChangJia is a geroler-type hydraulic motor designed for simple, reliable and environmentally conscious operation. It is manufactured to international green-energy specifications and offered in the BMTZ series (models BMTZ160–BMTZ800). The series covers geometric displacements from about 161 to 802 cm²/rev and is intended for industrial hydraulic drive applications requiring stable performance and long service life.

Product Advantages

- Precision-manufactured geroler gear set with low start-up pressure for smooth, efficient operation.

Application Scenarios

- Output shaft supported by tapered roller bearings to withstand high axial and radial loads, enabling high torque capacity.

- Disc distribution flow design that provides automatic compensation for high volumetric efficiency and extended life.

- Integral stator/rotor machining (forming and grinding) for compact size, high efficiency and durability.

- High-pressure shaft sealing suitable for series and parallel connections and a high power-density structural design.

3) Product value

- Reliable, low-maintenance operation and long life reduce downtime and lifecycle costs.

- High efficiency and smooth starts improve machine controllability and energy use.

- Broad model range and standardized mounting make the motor adaptable to many installations, simplifying inventory and replacement.

- Compliance with green manufacturing standards and an established sales/service network (online/offline) increase procurement convenience and after-sales support.

4) Product advantages

- Compact, high-power-density design delivering substantial torque in a relatively small, lightweight package (typical weights ~19–25 kg).

- Wide operating envelope: continuous pressures up to ~20 MPa (with higher intermittent/peak ratings), flows to ~125 L/min (continuous), and robust torque and power ratings across models.

- Smooth, reliable start-up and operation due to advanced geroler and flow-distribution design.

- Replaces older BM50/BMT50 models and benefits from ChangJia’s manufacturing and logistics support.

5) Application scenarios

- Mobile and construction equipment (excavators, cranes, augers and winches) requiring high torque at low speeds.

- Material-handling and industrial machines (conveyors, mixers, rotary drives, presses).

- Forestry and agricultural machinery (harvesters, feed conveyors).

- Marine and dredging equipment, mining machinery and other heavy-duty hydraulic systems where durability, high axial/radial load capacity and reliable continuous/intermittent duty are required.
