 2.Selection Guidelines


1. Total Load Calculation

Total Load = (Door Weight + Accessories) × 1.2 (safety factor)

Example:

200 lbs solid wood door + 50 lbs glass → Total Load = 300 lbs

→ Select a wheel set with total capacity ≥ 300 lbs (e.g., G1 Series: 400 lbs/wheel × 2 = 800 lbs total).

2. Installation Spacing Optimization

Dual-wheel spacing = Door width × 1/3 (reduces door bending risk)

Four-wheel spacing = Door width × 1/4 (for extra-wide or glass doors)

3. Environmental Adaptation

Coastal/high-humidity areas: Choose nickel-plated or stainless steel materials.

High-frequency usage: Prioritize ball bearings + nylon silent wheels.
