Engineered for Peak Reliability in Extreme Mining Duty

The unforgiving nature of mining operations demands components that can survive pressure spikes, abrasive dust, and constant vibration. The AL A2FM motor is built for this challenge, backed by a one-year warranty. Its robust construction provides exceptional resistance to extreme pressure and environmental hazards. Advanced sealing technologies and a hardened, high-strength housing ensure internal components are protected from contaminant ingress and hydraulic shocks that are commonplace during digging and loading cycles. This durability, exemplified in models identified by part numbers like 35866640 and 94186540, is critical for minimizing unplanned downtime and maximizing machine availability.

Powering the Komatsu Fleet: From Construction to Global Mining

While indispensable for massive mining shovels, the versatility of the A A2FM hydraulic motor extends across the diverse Komatsu (komatsu.com) product line, where hydraulic performance directly impacts productivity.

• Mining Excavators & Shovels: Beyond the PC4000-6, Komatsu’s ultra-class mining excavators rely on high-capacity hydraulic systems. The AL A2FM motor is often specified for driving heavy-duty cooling fans, conveyor winches, or pump drives in these machines. Its ability to deliver consistent torque under the highest loads is paramount.
• Wheel Loaders and Dozers: In large mining wheel loaders and bulldozers, the AA2FM provides reliable power for auxiliary systems such as radiator fans (parts like 63423540) or hydraulic pump drives, ensuring critical thermal management and implement function.
• Construction and Quarry Equipment: Komatsu’s extensive range of hydraulic excavators and wheel loaders for construction also utilize this motor platform for reliable performance. The motor’s design ensures smooth operation for applications requiring precise control.
• Global Parts and Compatibility: The widespread integration of the A2FM across Komatsu models is confirmed by its common presence in global parts networks. You will frequently find it cross-referenced under various OEM service codes, including 95066040, 63530840, 93270340, and 89659040, for everything from large mining equipment to specialized attachments.

FAQ (Frequently Asked Questions)

Q1: What makes the AL A2FM bent-axis motor particularly suitable for the auxiliary drives on a mining excavator?
A1: The bent-axis design offers superior volumetric efficiency and high power density, translating to more torque in a compact package. It excels at handling the continuous high-pressure operation (up to 450 bar) and shock loads typical in mining, making it ideal for demanding fan, pump, and winch drives.

Q2: How is the motor protected against the extremely abrasive dust and particulate matter in a mine?
A2: The A2FM employs a multi-stage sealing defense. High-performance shaft seals and protected housing interfaces are specifically designed to create a formidable barrier against fine dust and slurry ingress, which is essential for longevity in such environments.

Q3: Can this motor be used in both open and closed-loop hydraulic circuits found on Komatsu equipment?
A3: Yes, the AA2FM series is highly versatile. It is commonly applied in open-circuit systems for auxiliary functions (like fan drives 63423540) and is also well-suited for closed-loop hydrostatic drives in certain traction applications, offering flexibility for various system designs.

Q4: We need a replacement motor for a cooling system, referenced under Komatsu part number 93270340. Is it available?
A4: Absolutely. We specialize in providing high-quality, cross-compatible hydraulic motor solutions for Komatsu and other major OEM mining equipment.
