Key Features of BM5-S Series Hydraulic Motors
-
Compact short-version design, derived from the BM5 series, with significantly shortened body length (15%-20% shorter than the standard BM5 series), lightweight structure, and perfect adaptation to equipment with limited installation space while maintaining core performance.
-
High-precision end face distribution structure, with automatic wear compensation function, ensuring smooth operation at low speed, effectively reducing internal hydraulic loss and improving volumetric efficiency (up to 84%-91%) and operation stability.
-
High-strength double-row tapered roller bearings on the output shaft, adopting precision machining technology, which can bear large static and dynamic radial loads, balancing compact size and load-bearing capacity, and extending the service life of the motor.
-
Optimized dual-seal structure, combining high-temperature resistant oil seal and dust-proof seal, with strong sealing performance, capable of withstanding high back pressure, and suitable for harsh working environments such as dust, humidity and small-space long-time operation.
-
Excellent low-pressure start performance, with large starting torque (T启=(2~3) T额), which can realize stable start and continuous operation under low oil pressure conditions, adapting to the start-up needs of small and medium-sized equipment.
-
Flexible compatibility, compatible with the mounting flanges, output shafts and oil port types of the BM5 series, easy to replace and maintain, with high torque density and reliable performance, interchangeable with mainstream compact hydraulic motor models.
Performance Characteristics
Application Areas
-
Agricultural machinery: Small combine harvesters, compact rotary tillers, small feed mixers, seeders and fruit picking equipment.
-
Construction machinery: Compact hydraulic excavators, small rollers, road sweepers, garbage trucks and small lifting machinery, adapting to narrow construction sites.
-
Industrial equipment: Small conveyors, high-load winding machines, small injection molding machine preplasticizing screw drives and vulcanizing machines, suitable for equipment with limited internal space.
-
Forestry & Marine equipment: Small logging machines, fishing boat winches, small anchor machines, adapting to the limited space of small vessels and forestry equipment.
-
Other fields: Small mining auxiliary equipment, compact environmental sanitation equipment and small processing machinery, meeting the needs of small-space heavy-duty operation.
