Design highlights and performance characteristics
Hägglunds MB 84 motors use radial piston geometry to convert hydraulic power to high static torque with low rotational speed. The MB 84 14800 motor and MB 84 17900 motor are typically selected where compact footprint and high torque density are required, while larger frames such as the MB 84 33800 motor and MB 84 38000 motor are used where maximum torque and thermal capacity are critical. Key engineering attributes include reinforced housings, precision-machined pistons, heavy-duty bearings and high-integrity sealing systems that deliver:
- Continuous duty torque with stable temperature rise
- Resistance to pressure spikes up to the specified working pressure range
- Enhanced fatigue and explosion resistance for hazardous or confined environments
Typical mechanical applications
The MB 84 series is used as a primary drive element in hydraulic transmissions and direct-drive systems. Example integrations include:
- Agricultural power systems — hydrostatic traction or driven implements on large tractors (example OEM sites: www.deere.com, www.caseih.com). The MB 84 21300 motor is suitable for heavy tillage and traction drives.
- Construction equipment — swing and traction drives for large excavators and tracked vehicles (example OEM sites: www.cat.com, www.volvoce.com). The MB 84 22300 motor is often specified for swing applications and heavy duty lifting.
- Mining and quarry equipment — haul trucks, wheel loaders and rotary drives where the MB 84 25100 motor and MB 84 33800 motor provide the low-speed, high-torque capability required under abrasive duty (example OEM sites: www.komatsu.com, www.liebherr.com).
- Industrial drive systems — winches, cranes and dredge drives that require explosion-proof designs and robust pressure resistance; the MB 84 38000 motor is used for highest-duty actuation (example OEM sites: www.hitachicm.com, www.sandvik.com).
Each machine integration requires appropriate matching of hydraulic flow, pressure compensation and gearbox or coupling selection to achieve target torque and speed.
Installation, fluid and maintenance guidance
To maximize service life, use ISO-rated hydraulic fluids specified by system OEMs, maintain contamination control with β≥75 filtration at 10 µm or better, and implement effective thermal management. Preload and shaft alignment must conform to installation drawings in the product PDF. Routine inspection of seals and bearing condition, plus early detection of particle contamination, prevents premature wear.

FAQ
Q1: What makes the Hägglunds MB 84 radial piston motor suitable for mining?
A1: MB 84 motors combine low-speed high torque with reinforced housings and explosion-resistant features, enabling operation in abrasive, high-pressure and hazardous environments common in mining.
Q2: How should I size an MB 84 motor for a swing drive?
A2: Match required continuous torque and peak torque to the motor’s displacement and pressure capability, verify allowable rpm (15–390 rpm), and confirm gearbox ratio. Consult our technical team at https://www.baolilai-pump.com/contact_us/ for application-specific calculations.
Q3: Are MB 84 motors compatible with planetary gearboxes?
A3: Yes—MB 84 motors are commonly coupled to planetary or custom reduction gearboxes. Shaft interface and mounting must follow the OEM mounting specification in the data sheet.
Q4: What filtration and fluid are recommended?
A4: Use hydraulic fluid meeting OEM viscosity and cleanliness specifications; recommended filtration is β10≥75 (ISO 4406 target). Coolers and heat exchangers are advised in continuous high-power applications.
Q5: Where to obtain manuals and CAD drawings?
A5: Request PDF manuals and CAD from our website: https://www.baolilai-pump.com/contact_us/
