Common Challenges in Sourcing Gate & Door Wheels

The sliding wheel is the backbone of smooth gate operation. Yet many importers face these issues:
- Short lifespan – wheels that crack or deform under 200 kg load within months.
- Inconsistent dimensions – mismatched axle holes and track widths cause installation delays.
- Poor surface finish – rough castings that rust and jam.
- Unreliable lead times – unexpected delays disrupt your own delivery commitments.
At TJJ, we solve these problems through process control and vertical integration. As a founding casting factory in China, we control every step – from pattern making to final machining. Our sliding wheel production uses high-grade gray iron (G250 / G300) and ductile iron (QT400-18), achieving hardness of 180-220 HB and tensile strength up to 400 MPa.
Product Specifications & Factory Strength
Our standard sliding wheel series covers the most demanded sizes for residential and light commercial gates. All dimensions in inches (US standard).
| Model | Wheel Diameter | Track Width | Max Load (lbs) | Axle Type | Material |
|---|---|---|---|---|---|
| SW-201 | 3.0 in | 1.0 in | 600 | Ball bearing | Gray iron |
| SW-202 | 4.0 in | 1.25 in | 900 | Ball bearing | Ductile iron |

* Load capacities based on static tests. Refer to order confirmation for dynamic loading and track compatibility.
OEM/ODM & Custom Capabilities
As a sliding wheel factory with in-house pattern shop, we can produce non-standard diameters, custom axle configurations, and specific surface treatments (zinc plating, powder coating, or hot-dip galvanized). Typical MOQ is 500 pieces per size, but sample orders (50-100 pcs) are accepted for qualification. Lead time: 25-30 days for first orders; 20-25 days for repeat orders (depending on volume and coating complexity).
