QXG150 Drive Chain for Light-Duty Overhead Conveyor Systems

The QXG150 drive chain is the traction element at the heart of a light-duty enclosed-track overhead conveyor. It connects the drive sprocket to the take-up station, forming a continuous loop that carries trolleys, hangers, and small payloads through processing zones. With a 150 mm pitch and an 8 kg single-point load rating, this chain is engineered for compact layouts such as small-parts spray lines, assembly workstations, and finishing systems where floor space is limited and smooth, quiet motion is required.

Unlike heavy-duty forged chains used in automotive body shops, the QXG150 is a light-series chain built around a cross-hinge link design. The black-finished outer plates and precision-riveted pins give it a slim profile that runs inside a square enclosed track, protecting the moving parts from dust, overspray, and accidental contact.

Operating Environment & Suitability

QXG150 drive chains are designed for indoor industrial environments with ambient temperatures from -20°C to +120°C. The standard black oxide finish on the side plates provides basic corrosion protection for dry assembly and paint-shop conditions. For wet-process lines, steam-cure tunnels, or alkaline pretreatment zones, a zinc-phosphate or Dacromet-coated version can be supplied.

The enclosed square track shields the chain from direct spray and falling debris, making the QXG150 suitable for powder-coating booths, drying ovens, and clean-assembly cells. Continuous-duty applications should keep chain speed below 12 m/min to minimize dynamic loading on the small-diameter hinge pins.

Engineering Selection Guidance

When laying out a QXG150 conveyor line, treat the drive chain as a complete subsystem rather than an isolated component. The following points determine service life:

Match track radius to chain flexibility. The minimum horizontal bend radius for QXG150 is approximately 600 mm; tighter curves increase pin bending stress and shorten chain life.

Keep total chain tension below 30% of the rated breaking load. Light-duty chains rely on small pins; over-tensioning causes rapid pin wear and track noise.

Space trolleys at pitch multiples. The 150 mm pitch allows hanger spacing of 300 mm, 450 mm, 600 mm, and so on, which keeps the chain loaded evenly.

Position the drive station where chain wrap is greatest. A minimum wrap angle of 120° on the drive sprocket prevents tooth jumping under startup torque.

For replacement orders, confirm the exact pitch, plate width, pin diameter, and whether the chain uses standard or extended pin tabs. A worn sample is the fastest way to ensure dimensional compatibility.

Chain Construction & Component Breakdown

Component	Material / Specification	Function
Outer link plates	45# steel or 40Mn2, stamped and heat-treated	Carry tensile load and maintain pitch accuracy
Pins	40Cr, quenched and tempered, surface hardened	Hinge axis, transfers pull force between links
Bushings	20# steel or powder-metallurgy bushing	Bearing surface for pin rotation
Cross-hinge blocks	Cast or forged steel, black oxide finish	Allow multi-plane bending inside enclosed track
Surface finish	Black oxide / zinc phosphate / Dacromet	Corrosion protection for paint-shop environments

Installation & Tensioning Precautions

Lay the chain out on a clean surface and check the direction of travel before installation. Reversing the chain may cause the cross-hinge blocks to bind in curved sections.

Thread the chain through the track starting from the take-up station, keeping the chain taut enough to avoid twists but loose enough to prevent side-plate distortion.

Join the ends with the correct connecting link. The pin retaining clips or cotter pins must face outward so they can be inspected during operation.

Set the initial chain sag to approximately 1.5% of the loop length on the return side. Excessive tension overloads the drive bearings; too little tension causes tooth jump.

Run the conveyor unloaded for at least 30 minutes, then stop and retighten the take-up. New chains experience slight initial seating elongation.

Do not mix old and new chain sections in the same loop. Different wear stages create uneven pitch and increase vibration.

Typical Application Scenarios

Small-parts powder coating: brackets, hinges, and hardware move through spray, cure, and cool-down stations on compact QXG150 loops.

Electronics and appliance assembly: lightweight components are routed between workstations for wiring, testing, and packaging.

Furniture and wood-product finishing: chairs, frames, and panels are suspended for staining, drying, and lacquering.

Garment and textile handling: overhead conveyors in laundries and distribution centers use QXG150 chains to move hanging products quietly and efficiently.

Performance Features

Cross-hinge link construction permits smooth articulation in both horizontal and vertical planes, enabling complex three-dimensional conveyor layouts.

Hardened pins and precision bushings reduce friction losses, allowing lower motor power and quieter operation in light-duty cells.

Slim side-plate profile fits inside standard square enclosed track, protecting the chain from overspray, dust, and operator contact.

Consistent 150 mm pitch simplifies trolley spacing calculations and ensures uniform load distribution around the entire circuit.

Multiple corrosion-protection options extend service life in humid, alkaline, or powder-coating environments without changing the chain geometry.

FAQ

Q: 1:How is QXG150 drive chain different from QXG200 or QXG250 chain?

A:QXG150 has a 150 mm pitch and an 8 kg single-point load, making it the lightest-duty model in the QXG family. QXG200 and QXG250 use larger pitch, heavier plates, and larger pins for higher loads and longer spans.

Q: 2: Can I use QXG150 chain with an existing QXG200 track?

A:No. The track internal dimensions and sprocket tooth profile are matched to the chain pitch. Mixing series will cause binding, rapid wear, and unsafe operation.

Q: 3. What is the minimum order quantity and lead time?

A: Standard QXG150 drive chain is sold by the meter with a minimum order of 50 meters. Lead time is typically 15–20 days for stock material grades and 25–30 days for special coatings.

Q: 4: Do you supply matching drive sprockets and take-up units?

A: Yes. We can supply the complete drive package including sprocket, shaft, pillow block bearings, and take-up station, all matched to the QXG150 pitch.

Q: 5. How do I measure chain wear for replacement planning?

A: Measure the length of a 10-pitch section under light tension. If the measured length exceeds 1,530 mm (2% over the nominal 1,500 mm), replace the chain.
