CL226-1A (M8 Embedded Stud) & CL226-1 (Countersunk Hole) 60×60mm Zinc Alloy 180° Heavy Duty Industrial Cabinet Hinge

Full Technical Specifications

Shared General Parameters

  • Max Opening Angle: 180 degrees
  • Main Body Material: Die-cast zinc alloy
  • Pivot Pin: Carbon steel with nickel plating
  • Surface Treatment: Hinge body – matte black powder coating; pin – nickel plated (anti-rust & abrasion resistant)
  • Overall Size: 60mm length × 60mm width × 8mm thickness
  • Central Pin Diameter: Φ8mm

Core Product Features & Advantages

2.1 High Rigidity Die-Cast Zinc Alloy Body

Integral die-cast zinc alloy structure delivers excellent load-bearing capacity, anti-impact and anti-deformation performance. Perfect for heavy metal cabinet doors, mechanical equipment panels and industrial outdoor housings, long service life under continuous frequent rotation.

2.2 Dual Anti-Corrosion Surface Treatment

  • Hinge body: Black powder coated layer, scratch resistant, oil resistant, dust proof, beautiful matte appearance
  • Rotation pin: Nickel electroplated steel pin, low friction, smooth swing, effectively prevent pin rust and jamming Suitable for factory workshops, control rooms and mild outdoor environments.

2.3 Up to 180° Full Opening Angle

Maximum 180-degree flat opening design, completely flips the cabinet door to the side without blocking access, greatly convenient for internal wiring, component maintenance, equipment inspection and cleaning operations.

2.4 Two Optional Installation Modes for Different Scenarios

  1. CL226-1A (M8 Embedded Stud Version) Two pre-pressed M8 threaded studs on the back, directly pass through the cabinet plate and fasten with nuts from the reverse side. No drilling deep countersinks, super fast assembly, ideal for thicker metal frames and hollow cabinet walls.
  2. CL226-1 (Countersunk Hole Version) Four standard 90-degree countersunk mounting holes, flat head screws sink fully into the hinge surface for flush installation, no protruding parts, neat and tidy appearance, fits solid panels and standard sheet metal enclosures.

2.5 Stable Rotation Structure & Long Wear Life

Three-section hinge leaf interlocking structure with precision machined pin hole, tight fit and minimal wobble during rotation. The nickel-plated steel pin reduces friction loss, avoids loose hinge gap after thousands of opening cycles.

Wide Application Fields

  1. Industrial electrical control cabinets, low voltage distribution boxes, frequency converter enclosures, PLC equipment housings
  2. CNC machine tool protective doors, automation equipment frames, mechanical instrument boxes, test bench casings
  3. Outdoor communication equipment cabinets, battery energy storage boxes, waterproof industrial terminal enclosures
  4. Heavy sheet metal cabinets, tool storage boxes, large instrument test equipment housings
  5. Medical equipment housings, laboratory test equipment panels, environmental monitoring device casings

Installation Guide & Maintenance Tips

4.1 CL226-1A (M8 Stud) Installation Steps

  1. Drill two matching holes on the cabinet panel for M8 studs to pass through
  2. Insert the embedded M8 bolts from the front side
  3. Lock with flat washers and nuts on the backside and fully tighten
  4. Test 180° opening flexibility and hinge stability

4.2 CL226-1 (Countersunk Hole) Installation Steps

  1. Mark four hole positions, drill Φ8.4 holes and machine 90° countersink recesses
  2. Place the hinge flat on the panel, use M8 flat head screws to fix flush
  3. Verify door rotation smoothness and load balance

4.3 Installation Quantity Suggestion

  • Door height ≤ 700mm: Install 2 hinges symmetrically
  • Door height 700–1200mm or heavy steel door: Install 3 hinges to prevent sagging

4.4 Maintenance Notes

❌ Not suitable for long-term use in strong acid/alkali corrosive workshops, coastal high salt fog and heavily corrosive chemical environments.

  1. Wipe black coated surface regularly to remove metal dust and oil stains
  2. Add a small amount of dry lubricant to the pivot pin every 6 months to keep rotation smooth

Product Summary

CL226 series are heavy-duty 180° opening zinc alloy industrial hinges, split into CL226-1A (M8 embedded threaded studs) and CL226-1 (4 countersunk flush holes) two mounting versions. With high-strength die-cast zinc alloy body, black powder anti-corrosion coating and wear-resistant nickel-plated steel pin, they provide stable load capacity and smooth 180° full opening, serving as durable standard hardware for industrial electrical cabinets, machinery safety doors and various heavy-duty equipment enclosures.
