Product details

BMR(02) Orbit Motor Hydraulic (BMR Series Gerotor Hydraulic Motors)

The BMR series orbit motors are low-speed, high-torque hydraulic motors featuring an advancedGeroler gear setandshaft-distribution valve design. They are compact, lightweight, efficient, and durable, widely used in agricultural machinery, construction equipment, forestry machinery, and industrial applications.

I. Key Features

1. Low Speed, High Torque

• Output speed range:10–2000 RPM(varies by model).

• Maximum torque up to3000 N·m(e.g., BMR-800 model), ideal for heavy-duty starting and continuous high-load operations.

2. High Efficiency & Reliability

• Geroler gear set ensures low starting pressure, smooth operation, and high mechanical efficiency.

• Shaft-distribution valve automatically compensates for leakage under high pressure, ensuring long-term reliability.

3. Compact & Durable

• Cast iron housing for high strength in harsh environments.

• Deep groove ball bearings or tapered roller bearings handle high radial and axial forces.

• Built-in check valve eliminates the need for external drain lines, simplifying system design.

4. Flexible Adaptability

• Supports parallel or series configurations for varying power requirements.

• Interchangeable with similar products from brands likeETN Char-Lynn, M+S, and SAM.

III. Applications

1. Agricultural Machinery

• Combine harvesters, seeders, irrigation reels (driving harvesting, rotation, lifting).

2. Construction Equipment

• Excavators, loaders, cranes (slewing mechanisms for stable low-speed rotation).

3. Forestry Machinery

• Loggers, wood grabs, winches (high-load and field adaptability).

4. Industrial Equipment

• Plastic injection molding machines, presses, conveyors (precise speed/torque control).

5. Marine & Offshore Engineering

• Winches, anchor handling, oceanographic equipment (corrosion-resistant design for marine use).

------

IV. Selection Guidelines

1. By Load Requirements

• Light-duty (e.g., small sweepers):BMR-50 to BMR-100(51.7–100.5 cm³/rev).

• Heavy-duty (e.g., forestry winches):BMR-250 to BMR-800(252.6–801.8 cm³/rev).

2. By Speed Requirements

• High-speed (e.g., conveyors):BMR-50 to BMR-125(750–960 RPM continuous).

• Low-speed (e.g., presses):BMR-315 to BMR-800(175–310 RPM continuous).

3. By System Pressure

• Medium/low-pressure (≤17.5 MPa):BMR-50 to BMR-200.

• High-pressure (≤21 MPa):BMR-250 to BMR-800.

------

V. Maintenance & Precautions

1. Installation Requirements

• Ensure a flat mounting surface and rigid support to avoid vibration.

• Use flexible high-pressure hoses for inlet lines to eliminate stress and prevent pipe-supported motor operation.

2. Hydraulic Fluid Management

• Use clean, anti-wear, anti-oxidizing hydraulic oil with a filtration rating of≥10–15 μm.

• Fill the drain port with hydraulic oil before initial operation to expel air.

3. Regular Maintenance

• Replace hydraulic oil and clean filters every200 operating hours.

• Inspect shaft seals and bearings for wear; replace damaged components promptly.

4. Avoid Misoperation

• Do not exceed pressure ratings to prevent gear wear or seizure.

• Avoid radial loads exceeding specified limits to prevent output shaft damage.
