At Zala Machine Co., our legacy in Custom Shaft Manufacturing is built on three generations of technical excellence and a deep-rooted understanding of industrial power transmission. From our founding roots in the Polymer Extrusion Industry to our current status as a premier NJ machine shop, we specialize in the production of high-precision shafts for the most demanding applications. Whether you require massive 30” diameter industrial drive shafts or precision-machined components up to 96” in length, our facility is engineered to handle extreme scales and tight tolerances that standard job shops simply cannot reach.
Our comprehensive Custom Shaft Manufacturing process begins with our specialized Reverse Engineering services—perfect for restoring legacy machinery when OEM prints are no longer available. To expert material sourcing of high-grade alloys, stainless steel, and exotics, or through Leveraging advanced CNC Turning and 5-Axis Milling, we execute complex geometries including Precision Spline Cutting, keyways, and stepped diameters with absolute repeatability. To ensure peak operational performance, every precision diameter undergoes rigorous Grinding for superior surface finishes and a final multi-point Inspection to guarantee alignment and concentricity. Once perfected, we handle secure Shipping across North America, ensuring your mission-critical shafts arrive ready for immediate installation.
Custom Shaft Manufacturing for single and twin-screw extruders. We maintain tight tolerances on length, diameter, and straightness to ensure optimal torque transfer and alignment. We reverse engineer and machine new spline, geared, drive, thrust shafts for many Gearboxes that we repair in our Gearbox Repair Department.
Engineered for heavy industrial use, our drive shafts are machined to handle high rotational loads with minimal vibration.
Integration of complex features including internal and external splines, keyways, and precision-cut gears to meet specific mechanical requirements.
Specialized shafts featuring deep-hole bores for coolant passage, weight reduction, or internal component housing. With our in house Gundrilling and Honing capabilites we are specialists in shafts that require thru bores for internal components or weight reduction. W
CNC Turning & CNC Milling: High-accuracy machining for diameters up to and lengths up to 144″(3650mm).
5-Axis Milling: For complex shaft ends, cam profiles, and non-standard geometries.
Gundrilling & Honing: In-house deep-hole drilling and ID finishing to mirror finishes and tight tolerances.
Precision Grinding: Achieving superior surface finishes and exact dimensional accuracy for bearing seats and seal surfaces.
The performance of a precision shaft is dictated by its base material. We don’t just “order steel”—we source specific alloys suited for high-torque and high-wear environments, ensuring full traceability with Material Test Reports (MTRs).
High-Torque Alloy Steels: 4140/4340: Our go-to for drive shafts requiring high fatigue strength and toughness.
Nitralloy 135 Mod: Preferred for shafts requiring extreme surface hardness (via nitriding) while maintaining a ductile core to prevent snapping under shock loads.
Corrosion-Resistant Alloys: 300 & 400 Series Stainless: Critical for polymer extrusion components handling corrosive resins or wash-down environments.
17-4 PH: For applications needing the corrosion resistance of stainless with the high strength of an alloy steel.
Tool Steels & Specialty Metals: D2, H13, P20, Inconel, Hastalloy: Utilized for specialized shaft ends or components subjected to extreme heat and abrasion.
Technical Processing: Stress Relieving, Heat Treating, Nitriding, Plating, Precision Grinding.
Traceability: Every shaft we produce is backed by verified heat-lot documentation to ensure consistent performance across production runs.
Quality at Zala is a multi-generational discipline, combining decades of legacy knowledge with modern inspection technology.
Dimensional Tolerances: We maintain concentricity and rotational accuracy within .0005” TIR.
Surface Finish: Precision grinding capabilities to achieve finishes as fine as 8 Ra on bearing and seal surfaces.
Straightness Verification: Critical inspection for long-bed shafts and gundrilled components to ensure zero-vibration operation.
Bore & Internal Integrity: Specialized borescope inspection and gauge verification for all gundrilled and honed IDs.
Calibrated Inspection: All metrology equipment is NIST-traceable to ensure absolute measurement reliability.
When the success of your equipment depends on the integrity of a single shaft, precision is the only option. Our engineering team is ready to review your specifications and provide a technical manufacturing assessment for your project.
