1. Product Overview & Market Position

2. Reinforced Structural Design

1. Super Thick Link Plate: Double-layer thickened 45# steel stamping, higher anti-tensile and anti-impact performance.
2. Reinforced One-Piece Pusher Lugs: Larger and thicker push blocks on outer chain plates, stronger bearing capacity, not easy to deform under heavy impact.
3. Oversized Solid Alloy Steel Pin & Wear Bushing: Enlarged pin diameter, carburizing quenching treatment, low wear loss under long-term heavy traction.
4. Heavy-Duty Connecting Link: Thickened spring clip connector, stable locking for heavy-load continuous operation.

3. Material & Heat Treatment Technology

• Main raw material: 45# medium carbon alloy steel, higher strength than Q235 carbon steel QXG150 chain.
• Full quenching process: Link plate, pin, bushing and push lugs all carburized quenched, surface hardness HRC43–49, excellent wear and fatigue resistance.
• Optional surface anti-rust treatment: Standard black oxide; hot galvanized version for high humidity pre-treatment workshops.

4. Core Technical Parameters

• Standard pitch: 200mm, only matched with QXG200 series track, 8/10/12 tooth heavy-duty sprocket and supporting spring buffer drive shaft assembly.
• Minimum breaking load: ≥110KN, single hanger allowable load up to 150kg.
• Applicable running speed: 0.2–10m/min, low-speed stable traction for super heavy workpieces.
• Working temperature: -20℃ ~ 180℃, compatible with high-temperature curing oven environment.

5. Matching Supporting System

1. Drive components: QXG200 heavy-duty quenched sprocket, QXG200 reinforced spring buffer overload drive shaft assembly.
2. Conveying accessories: QXG200 thickened C-type closed track, heavy-load reinforced trolley hangers, large tension idler sprocket.

6. Main Application Heavy-Duty Scenarios

• Agricultural machinery, truck frame, engineering machinery large parts spraying & powder coating lines
• Cabinet, elevator part, large metal workpiece electrophoresis surface treatment production lines
• Extra long suspension conveying lines over 150 meters with heavy single hanging load

7. Customization Service Items

1. Custom reinforced thickened push lugs for ultra-heavy workpiece conveying.
2. Custom chain length, special connectors for steep climbing and sharp bend track layout.
3. Stainless steel material upgrade for corrosive pickling and chemical processing workshops.
4. One-stop OEM matching: Supply chain, sprocket and heavy-duty drive shaft assembly together as a full set conveyor drive kit.

8. Maintenance & Fault Prevention Tips

1. Biweekly full lubrication on pin and bushing clearance with high-pressure high-temperature grease.
2. Monthly inspection on push lug deformation and abrasion; replace chain when lug thickness wear exceeds 1.5mm.
3. Must equip QXG200 special heavy spring buffer drive shaft to avoid chain breakage caused by overload jam.

9. FAQ

1. Can QXG200 drive chain be replaced with QXG150 chain?
    
   No. QXG200 pitch is 200mm while QXG150 pitch is 150mm, dimension mismatch, cannot mesh with each other’s sprocket and track.
2. What’s the service life difference between QXG200 and QXG150 chain?
    
   Under full load operation, QXG200 thickened quenched chain can reach 2–3 years service life, much longer than standard QXG150 chain.
3. Is sample chain available for load test?
    
   Yes, we can provide 1–2 meters sample chain for customer load test, bulk order lead time 8–12 working days.
