2. Core Product Advantages

2.1 Large-Size High-Strength Die-Cast Zinc Alloy Body

One-piece high-pressure zinc alloy die-casting forms a rigid whole structure, excellent impact resistance and anti-deformation ability. 90×60mm enlarged panel design greatly improves bearing capacity, perfectly matches heavy equipment doors and thick steel sheet cabinets, effectively avoid hinge bending or sagging under heavy load.

2.2 Durable Black Powder Coating Protection

Dense black powder coating covers the entire zinc alloy surface, isolates air, moisture, workshop oil mist, dust and weak corrosive liquid to prevent metal oxidation and rust. Matte industrial finish resists scratches and abrasion, easy to wipe and maintain in harsh factory environments.

2.3 Φ8 Oversized Solid Steel Pivot Pin

Thickened Φ8 solid steel central pin adopts precision matching process, small rotation clearance, no shaking or loose during frequent opening and closing. Low friction operation ensures tens of thousands of cycles without gap enlargement, significantly extend the service life of the hinge.

2.4 180° Full Flat Opening Structure

180-degree maximum turnover angle lets the cabinet door lay completely flat beside the frame, zero obstruction during internal circuit inspection, equipment maintenance, component replacement and daily cleaning, greatly improve operation efficiency.

2.5 Integrated M8 Threaded Studs for Fast Through Installation

Two M8 threaded studs are pre-cast on the back of the hinge, only need to drill simple through holes on cabinet wall, pass the studs through and lock with nuts on the reverse side. Simplify installation procedures, save assembly time, especially suitable for thick aluminum profiles, hollow enclosures and heavy metal plates.

3. Application Scopes

1. Large power distribution cabinets, industrial frequency converter cabinets, PLC control enclosures and electrical switchgear boxes
2. CNC machine tool protective doors, automation equipment heavy frames, test bench cabinet panels
3. Energy storage battery cabinets, outdoor communication equipment boxes, waterproof large monitoring enclosures
4. Heavy-duty sheet metal tool cabinets, mechanical equipment safety covers, engineering equipment housings
5. Laboratory large analytical instruments, environmental monitoring central control boxes and industrial testing equipment doors

4. Installation & Maintenance Guidelines

Installation Steps

1. Drill two through holes matching M8 studs on the cabinet mounting panel
2. Pass the two M8 embedded studs of CL226-5A through the holes from the outer side
3. Add flat washers and spring washers, tighten lock nuts firmly on the inner side
4. Test 180° opening smoothness and overall fastening stability

Installation Quantity Recommendation

• Door height ≤ 800mm: Install 2 hinges symmetrically
• Door height 800–1300mm or overweight steel door: Install 3 hinges to prevent deflection and sagging

Maintenance Notes

❌ Not recommended for long-term deployment in strong acid & alkali corrosive workshops, coastal high salt fog and severe chemical vapor surroundings.

1. Regularly wipe the black coating surface to remove metal scraps and grease stains
2. Inject a small amount of dry lubricant onto the Φ8 steel pivot pin every 6 months for smooth and silent rotation
