At Specialty Gear Drives, we specialize in the complete forensic restoration and repair of the heavy-duty gearboxes that power Aaron Process machinery
All Fields Must Be Filled Out
When the gearbox driving your Aaron Process Equipment mixer or blender fails, your entire batch production comes to a grinding halt. Every hour of lost production costs your facility valuable revenue and disrupts your supply chain. At Specialty Gear Drives, we specialize in the complete forensic restoration and repair of the heavy-duty gearboxes that power Aaron Process machinery. We don’t just replace parts; we engineer comprehensive solutions to get your critical mixing equipment back online faster and for a fraction of the cost of buying new.
Aaron Process Equipment is highly regarded for manufacturing some of the most robust mixing and blending machinery in the industry. Their heavy-duty Sigma Blade Mixers, Double Arm Mixers, and Mixer Extruders are engineered to handle incredibly demanding, highly viscous materials such as adhesives, ceramics, carbon pastes, and heavy-density plastics. To manipulate these stubborn materials, Aaron Process machines rely on massive, high-torque gearboxes. These drives are specifically designed to deliver immense rotational power at low speeds, driving the heavy counter-rotating mixing arms and lower discharge screws through thick, phase-changing materials without stalling.
Repairing a high-torque mixer drive requires specialized knowledge and precision machining. Our process begins with a complete teardown and a deep chemical cleaning to strip away all hardened product, grease, and metallic debris. Our technicians then perform a meticulous inspection, measuring every housing bore, shaft journal, and internal tolerance to identify the exact root cause of the failure. We rebuild these units using only premium, high-capacity Timken or SKF bearings engineered to withstand extreme mixing loads. If your internal gears have been destroyed by contamination or metal fatigue our in-house manufacturing division can reverse-engineer and precision-grind new gearing up to 20 feet in diameter. We manufacture these replacement gears to match or exceed the original OEM hardness and profile specifications. Finally, we install upgraded seal systems to prevent future material ingress and subject the fully assembled unit to a rigorous dynamic load test.
Processing highly viscous and heavy-density materials puts an extraordinary amount of stress on the internal drive train. The most common cause of failure in these heavy-duty mixing gearboxes is bearing fatigue. The constant, extreme radial and axial loads generated by the mixing arms eventually wear down the internal bearings, causing the shafts to misalign and the
gears to clash. Additionally, contamination is a major threat. As packing glands and seals wear down over thousands of hours of operation, abrasive process materials can migrate past the seals and directly into the gear case. Once inside, these materials act like a grinding paste, chewing through the helical gear teeth and scoring the bearing journals. This leads to severe overheating, excessive vibration, and ultimately, catastrophic gearbox failure.
We understand that in process manufacturing, downtime is your biggest enemy. That is why we offer 24/7 emergency rush repair services designed to overhaul your Aaron Process gearbox in days, not months. We handle all the heavy lifting, offering free nationwide pickup and free delivery to completely eliminate your freight logistics and costs. Before any machining begins, we provide a free, comprehensive quote so you know exactly what the restoration will entail. Most importantly, we stand firmly behind our engineering and craftsmanship. Every Aaron Process gearbox we rebuild, and every custom gear we manufacture, is backed by our industry-leading 24-Month Warranty.
Don’t let a broken mixer drive ruin your production schedule.
