Danfoss TMT Series Heavy-Duty LSHT Hydraulic Motors

Product Overview: The Danfoss TMT Series orbital motors represent the pinnacle of power in hydrostatic drive technology. Featuring advanced Disc Valve technology, these Low Speed High Torque (LSHT) motors are specifically engineered to withstand high axial and radial loads. Their robust construction ensures long service life even under continuous high-pressure operations. This page features core models including TMT250, TMT315, TMT400, and the ultra-large TMT470V, with specific part numbers like 151Z3305 and 151Z3010. These motors are the premier choice for forestry harvesters, asphalt pavers, drilling rigs, heavy-duty winches, and material handling equipment.

Key Technical Advantages:

• Elite Power Delivery: The TMT series offers industry-leading power density for its size, delivering consistent and massive torque output.

• Superior Load Capacity: Reinforced axial and radial bearings allow these motors to directly drive wheels or conveyor mechanisms without external support.

• Precision Disc Valve Technology: Ensures high volumetric efficiency and exceptional smoothness even at ultra-low speeds, significantly reducing pressure ripples.

• Extreme Pressure Resilience: Supports peak pressures up to 350 Bar, effortlessly handling the frequent start-stops and shock loads of construction machinery.

• Target Applications: Wood chippers, excavator attachment drives, concrete pump slewing mechanisms, and heavy-duty industrial conveyor belts.
