Product Description

LIC Hydraulic provides the BMTZ & BMTZR Series, a premium range of high-torque, disc-valve orbit motors engineered for relentless industrial service. Spanning displacements from 500ml/r to 800ml/r, the BMTZ series utilizes an advanced Geroler set and precision-engineered disc valve distribution to deliver maximum power density. The BMTZ-500-Z4-YD is designed to handle extreme operational stresses, providing stable rotation even at ultra-low speeds. Whether for heavy-duty winching, marine deck machinery, or industrial rotary drives, the BMTZ series is the definitive choice for reliability and torque.

Technical Highlights

  • Superior Torque Output: Optimized Geroler geometry provides high starting and running torque, essential for heavy-load mobile applications.

  • Disc Valve Distribution: High-precision distribution ensures minimal internal leakage and maximum volumetric efficiency over the entire life of the motor.

  • High Load Capacity: Integrated oversized tapered roller bearings allow the motor to handle significant axial and radial forces without auxiliary supports.

  • Durable Sealing System: Equipped with high-pressure shaft seals that resist degradation and leakage under high-pressure spikes.

Application Areas

  • Construction Machinery: Powering the winches and rotary heads of drilling rigs and earthmoving equipment.

  • Marine & Offshore: High-capacity deck cranes, anchor winches, and fishing equipment.

  • Industrial Drives: Driving heavy-duty conveyors, mixing tanks, and material processing units.

Expert Maintenance Tips

  • Proper Priming: Always pre-fill the motor housing with filtered hydraulic oil through the case drain before initial startup to prevent dry-start wear.

  • Monitor Case Drain Pressure: To protect the shaft seal, ensure the case drain line is connected and backpressure is kept below 5 bar.

  • Fluid Cleanliness: To maintain the precision of the Geroler internals, ensure the hydraulic fluid meets a cleanliness level of ISO 18/16/13.
