Aluminum endrings are the critical connection parts that mount on both ends of engraved rotary nickel screens, allowing the screen to run smoothly and stay aligned on the rotary printing machine. A properly machined endring helps maintain concentricity, repeat accuracy, and stable rotation, which directly affects downtime risk and print consistency in long production runs.
At Hanze, we supply die-cast + CNC-machined aluminum endrings for common rotary screen systems (Stork/Stork type, Reggiani type, J. Zimmer type). For customers running continuous lines, we focus on batch-to-batch dimensional consistency, reliable lead time, and OEM support based on drawings or physical samples.
This category includes popular endring types used in mills and printing houses, such as:
•STORK Type (e.g., 820 mm / 1018 mm, and related variants)
•REGGIANI Type (e.g., 640 / 725 / 819 / 914 / 1018 mm; standard & drilled options)
•J. ZIMMER Type (e.g., 640 mm short / standard)
If you are replacing an existing endring, the fastest way is to match by type + repeat + ID/OD. If you're not sure, send a photo of your current endring and screen label, and we'll recommend a compatible option.
Below are typical manufacturing and specification ranges (customization available for OEM projects):
| Item | Options / Range |
|---|---|
| Material | High-grade aluminum alloy (die-cast) |
| Process | Die casting + precision CNC machining |
| Surface | Smooth finish with anti-corrosion coating |
| Outer Diameter (OD) | Customizable, typically 140–180 mm |
| Inner Diameter (ID) | Common options 100 / 110 / 125 mm, or per drawing/sample |
| Repeat Sizes | 640 / 726 / 820 / 914 / 1018 / 1168 / 1206 / 1450 / 1680 (and custom repeats) |
| OEM Support | Yes — drawings or physical samples accepted |
Why it matters for high-volume production:
Consistent machining tolerances and stable alloy quality help keep endrings interchangeable across batches—important for plants managing repeat programs and multi-line production.
•Dimensional stability for long runs: CNC machining to close tolerances supports accurate screen alignment and stable rotation.
•Durability for industrial handling: Die-cast construction helps control deformation and improves service life in real factory use.
•Compatibility across common systems: Options for Stork, Reggiani, Zimmer and other widely used rotary setups.
•OEM-ready supply: Custom ID/OD, drilled patterns, and repeat requirements supported via drawings/samples.
•Bulk supply & production planning: Typical MOQ and lead-time expectations are set for program orders (details confirmed per model/order size).
Endrings and nickel screens work as a system. If you are also sourcing rotary nickel screens, ordering them together helps reduce mismatch risk and speeds up replacement cycles.

Q1: What do aluminum endrings do in rotary screen printing?
They are installed on both ends of an engraved rotary nickel screen so the screen can be mounted on the machine and run with stable rotation and alignment.
Q2: How do I select the right endring—by mesh or by repeat?
Endrings are primarily selected by system/type (Stork/Reggiani/Zimmer) and repeat/circumference, then confirmed by ID/OD and any special features (e.g., drilled patterns).
Q3: Can you support OEM sizes or custom dimensions?
Yes. OEM support is available based on client drawings or physical samples, including custom ID/OD ranges and repeat requirements.
Q4: What repeats do you commonly supply?
Common repeat sizes include 640, 726, 820, 914, 1018 and more, with additional repeats available for special requirements.
Q5: What's your typical production setup (materials/process) for consistent batches?
We use die casting + precision CNC machining and anti-corrosion surface finishing, which supports dimensional stability and repeatable performance across batch orders.
