Cross Conveyor Chains

Hangzhou Ocean Industry Co., Ltd. is one of the most experienced manufacturers and suppliers of cross conveyor chains in China. Welcome to wholesale customized cross conveyor chains at competitive price from our factory. Good service and quality products are available.

The chain is driven by the driving chain and runs continuously in the track. It plays the role of suspension and transmission in the conveyor. The conveyor chain is bidirectionally articulated, so in addition to linear motion, it can also follow the movement of the track. Curved shape, completing spatial curvilinear motion in horizontal and vertical planes.

The figure below shows a simplified diagram of the conveyor chain of the XF series conveyor. Each section (T) has 4 running wheels, 4 guides and 2 cross sections. The running wheel and the guide wheel are connected by double chain plates through cross joints and pins. After the detachable hanging plate or fixed hanging plate is hung in the middle of the pin shaft, the workpiece can be transported. Their running wheels and guide wheels both adopt double-row ball structures, and their sizes are generally φ38 and φ45 bearings as guides and running wheels, and the track width is adjusted accordingly.

Industrial production:

In manufacturing (e.g., auto, machinery, electronics), it transports parts and products.

In chemical industry, for chemical substances.

In food processing, for raw materials and products with hygienic materials.

In paper industry, for paper and pulp.

Mining and energy: Transports ores and coal in mines and fuels in power plants.

Construction: For building materials and in some construction equipment.

Logistics and warehousing: In warehouses and logistics centers for sorting.

Agriculture: For agricultural materials and in harvesting and processing.

High-Temperature Environments (200–280°C)

For curing ovens, drying tunnels, and heat-treatment lines, select XWF-series chains with heat-resistant pins and bushings. The XWF-381 and XWF-500 models feature alloy steel construction rated for continuous operation at 280°C. Pair with high-temperature chain oil and schedule automatic lubrication at 4-hour intervals to prevent pin galling.

Corrosive / Humid Environments (Electroplating, Pretreatment)

In acid-alkali exposure zones such as pretreatment tunnels and electroplating lines, specify nickel-plated or Dacromet-coated chains. Standard self-color chains will develop surface rust within 2–4 weeks in pH < 4 environments. Our Dacromet-coated XWF-400 has been field-tested for 12 months in a zinc-phosphating line with zero corrosion-related failures.

Food and Pharmaceutical Processing

When cross conveyor chains operate in food-contact zones, nickel plating combined with food-grade lubricant is mandatory for HACCP compliance. Our WF-350-Ni (nickel-plated variant) is available with FDA-compliant surface certification. Contact our engineering team for material traceability documentation.

• 350 mm pitch (WF/XWF-350): Best for light-medium loads (50–150 kg/hanging point). Painting lines, garment conveyors, electronics assembly. Min curve radius: R600 mm.

• 381 mm pitch (WF/XWF-381): Industry standard for medium-duty enclosed track. Breaking load up to 90 KN. Auto parts finishing, appliance coating lines.

• 400 mm pitch (WF/XWF-400): Medium-heavy duty. Larger workpieces needing wider plate clearance. Up to 150 kg/point on enclosed track.

• 500 mm pitch (XWF-500): Heavy duty for I-beam track. Single-point lift 150–250 kg. Foundry handling, large-component assembly.

Each cross conveyor chain link consists of the following precision-engineered components:

1. Walking Wheels : Double-row ball bearing construction, φ38/φ45 mm diameters. Bearing steel GCr15, hardness HRC 58-62.

2. Guide Wheels : Double-row ball bearing, matched to track inner profile. Ensures smooth curve negotiation without derailment.

3. Cross Joints : Precision-machined from 40Cr alloy steel. Enables bidirectional articulation for 3D curve tracking.

4. Link Plates: Dual-plate design from hardened carbon steel C45. Shot-blasted and quality-inspected.

5. Connecting Pins: High-tensile alloy steel, riveted or cotter-pinned. All pins undergo MPI for micro-crack detection.

6. Hanger Plates: Bolt-on or welded options for attaching spreaders. Various lengths for different compatibility.

 Auto Parts Coating Line - 1,200 m XWF-381 Chain

A Japanese automotive Tier-1 supplier required replacement cross conveyor chains for their existing XF-series enclosed track painting line. Original chains (from another supplier) showed premature pin wear at 220°C curing oven section, with chain elongation exceeding 3% within 8 months. Ocean Industry supplied XWF-381 with heat-resistant pins and Dacromet link plates for oven section, and standard zinc-plated chains for ambient sections. After 18 months continuous operation (16h/day), elongation measured below 1.2% with zero pin failures. Customer has since standardized on Ocean Industry chains for all 3 coating lines.

Manufacturer Direct - Why It Matters

When you purchase cross conveyor chains from Ocean Industry, you buy direct from the factory floor in Hangzhou, China - not through a middleman. This means: (1) Strict quality control at every production stage - raw material inspection through final load testing. (2) Direct technical support from engineers who designed your chain. (3) Rapid spare parts availability - common components stocked for same-week dispatch. (4) Custom engineering - non-standard pitch/profile manufactured to drawings, MOQ as low as 20 meters.
