Home / Industrial Gearbox Repair & Custom Gear Manufacturing | Zala Machine Co.
Unlike typical repair shops that act as simple assembly houses, Zala Machine Co. operates as a full-scale manufacturing facility. This distinction is especially critical for Industrial Gearbox Repair in NJ, as it essentially allows us to reverse-engineer and manufacture obsolete gears, shafts, and internal components entirely in-house. Furthermore, whether you are operating a high-torque twin-screw system or a specialized single-screw unit, our team provides comprehensive failure analysis, housing bore restoration, and precision gear timing. Ultimately, we don’t just wait for parts; instead, we manufacture the solutions needed to get your facility back to peak production capacity.
To ensure every unit leaves our shop in peak condition, we follow a rigorous, Zala Industrial Gearbox Repair documented restoration process:
To start, every gearbox undergoes a thorough external cleaning to remove years of production buildup. Doing so allows our technicians to perform a clean disassembly and, consequently, accurately inspect the housing for external cracks or leaks.
First, we carefully disassemble the unit, while simultaneously documenting the orientation and position of every gear, shaft, and shim. Ultimately, this step is critical for identifying the ‘root cause’ of the failure rather than just treating the symptoms.
Using precision measuring tools, we inspect:
Gear Teeth: Checking for pitting, spalling, or micro-cracking.
Shafts: Checking for runout, wear at bearing seats, and seal surface integrity.
Bores: Checking for ovality or wear in the main housing bores.
Ultimately, this is where the Zala Advantage in Industrial Gearbox Repair sets us apart. Specifically, if a part is unavailable or has a 20-week lead time, we immediately leverage our in-house capabilities to reverse-engineer the worn component. By doing so, we can manufacture the solution ourselves, thereby eliminating delays and getting your operations back online.
Gear Manufacturing: We can machine new gear blanks and use our range of gear cutting vendors to cut precision gear teeth.
Housing Repair: We utilize our CNC boring mills to sleeve worn bearing seats, restoring perfect shaft alignment.
Shaft Recovery: Precision grinding and plating to restore worn seal diameters. Shaft machining has been one of the corner stones of Zala Machine since day one. We fix and machine new shafts for all types of applications.
Once the components are ready, the unit is reassembled with high-grade bearings and seals. Particularly for twin-screw gearboxes, we perform meticulous timing and backlash checks to ensure perfectly synchronized output. As a result, the restored unit meetsāand often exceedsāOEM specifications.
We understand the varying complexities of drive systems across the polymer industry:
Single-Screw Gearboxes: Focus on thrust bearing integrity and axial load management.
Twin-Screw Gearboxes: Specialized alignment and timing for co-rotating or counter-rotating systems.
Capacity: We have the lifting capacity and large-scale machinery to handle everything from lab-scale units to massive production gearboxes.
While most repair shops are just assembly housesārelying on ordering parts and waitingāat Zala, we operate as a complete manufacturing facility. For instance, if your gear is stripped and the OEM is six months out, we simply machine a new one in-house. In this way, we maintain total control over both the quality and the timeline.
Our advanced CNC machining centers and an experienced team of engineers guarantee excellent results. Regardless of the complexity of the project or specification, we are ready to meet your requirements. Our machines are equipped with the latest technology.
