Key Features of BM5W Series Hydraulic Motors
-
Waterproof heavy-duty design, derived from the BM5 series, with advanced three-layer waterproof sealing technology (waterproof oil seal, waterproof gasket, dust-proof cover), reaching IP67 waterproof level, effectively preventing water, dust and other impurities from entering the motor, adapting to long-term operation in humid, rainy or water-exposed environments.
-
High-precision end face distribution structure with automatic wear compensation function, combined with waterproof protection design, ensuring smooth operation at low speed, effectively reducing internal hydraulic loss, and the volumetric efficiency can reach 84%-91%, with excellent operation stability even in harsh wet conditions.
-
Reinforced high-strength double-row tapered roller bearings on the output shaft, adopting precision machining and anti-corrosion heat treatment technology, which can bear larger static and dynamic radial loads than the standard BM5 series, balancing waterproof performance and load-bearing capacity, and greatly extending the service life of the motor.
-
Optimized anti-corrosion structure, the motor shell adopts anti-rust and anti-corrosion materials and surface treatment technology, which can resist corrosion of seawater, rainwater and other corrosive media, suitable for harsh working environments such as marine, coastal and outdoor wet areas.
-
Excellent low-pressure start performance and large starting torque (T启=(2~3) T额), which can realize stable start and continuous operation under low oil pressure and wet conditions, and the waterproof system can maintain stable performance for a long time without leakage.
-
Flexible compatibility, compatible with the mounting flanges, output shafts and oil port types of the BM5 series, supporting customized waterproof upgrading according to user needs, easy to replace and maintain, and interchangeable with mainstream waterproof hydraulic motor models.
Performance Characteristics
Application Areas
-
Marine equipment: Ship anchor winches, net hauling equipment, steering systems, marine crane drives, offshore operation equipment, with excellent seawater corrosion resistance and waterproof performance, adapting to the complex marine working environment.
-
Construction machinery: Outdoor hydraulic excavators, road rollers, heavy-duty cement mixers, construction site lifting machinery, adapting to rainy, humid construction sites and coastal construction projects.
-
Mining machinery: Underground coal shearers, roadheaders, mine hoists in wet mines, adapting to the humid and dusty working conditions of mining sites.
-
Agricultural machinery: Large combine harvesters, heavy-duty rotary tillers, irrigation equipment working in rainy and humid fields, ensuring stable operation in wet agricultural scenarios.
-
Other fields: Outdoor environmental sanitation equipment, coastal engineering machinery, underwater operation auxiliary equipment, meeting the needs of waterproof and heavy-duty operation in various wet environments.
