Key Features of BM5 Series Hydraulic Motors
-
Advanced end face distribution design, which ensures smooth operation at low speed and has automatic wear compensation function, effectively reducing internal hydraulic loss and improving operation stability.
-
Double-row tapered roller bearings on the output shaft, which can bear large static and dynamic radial loads, significantly enhancing the load-bearing capacity and service life of the motor.
-
Optimized shaft seal structure with strong sealing performance, capable of withstanding high back pressure, and suitable for harsh working environments such as dust, humidity and heavy load.
-
Excellent low-pressure start performance and large starting torque, which can realize stable start and continuous operation under low oil pressure conditions, adapting to the needs of heavy-duty start scenarios.
-
Flexible structural design, supporting various mounting flanges, output shafts and oil port types, which can be flexibly matched with different working mechanisms and installation requirements.
-
High torque density, reliable performance and strong environmental adaptability, interchangeable with mainstream heavy-duty hydraulic motor models, widely used in low-speed and heavy-duty working scenarios.
Performance Characteristics
The BM5 series hydraulic motors belong to end face distribution orbital geroler hydraulic motors, which are dedicated to low-speed and heavy-duty continuous operation with stable and reliable performance. The displacement ranges from 80.0 cm³/rev to 1250.0 cm³/rev, covering a wide range of torque (194-2650 N·m) and speed requirements, and the maximum intermittent pressure can reach 20.0 MPa, providing strong power support for various heavy-duty equipment. The motor has the advantages of smooth operation, low noise, long service life and high efficiency, and is an ideal choice for heavy-duty industrial, agricultural and marine applications.
Application Areas
BM5 series hydraulic motors are widely used in various heavy-duty industries due to their excellent high-torque and low-speed performance, including:
-
Agricultural machinery: Large combine harvesters, heavy-duty rotary tillers, feed mixers and large-scale agricultural irrigation equipment.
-
Construction machinery: Hydraulic excavator travel and slewing drives, large rollers, cement mixers and heavy lifting machinery.
-
Industrial equipment: Large conveyors, winding machines, injection molding machine preplasticizing screw drives and vulcanizing machines.
-
Mining machinery: Coal shearers, roadheaders and mine hoists, adapting to harsh mining working environments.
-
Marine equipment: Ship anchor winches, fishing boat net hauling equipment and ship steering systems.
Model Coding Explanation
The model coding of BM5 series hydraulic motors is composed of 7 parts, which clearly indicates the motor type, displacement, output shaft type, flange type and oil port type. For example, “BM5 500 H4 A Y5” means:
-
Type: BM5 (end face distribution orbital geroler hydraulic motor)
-
Displacement: 500 (corresponding to 500.6 cm³/rev)
-
Output shaft type: H4 (40mm rectangular spline, 8-40×35×7)
-
Flange type: A (large flange with 4×18mm mounting holes, φ160mm spigot)
-
Oil port type: Y5 (inlet and outlet M18×1.5, drain port M14×1.5)
