From a suspension system perspective, the square spring disc axle is designed with an E distance of 285 mm, an F value of 130 mm, and reinforcement component thickness ranging from 35 to 87 mm. In addition, precise calculations for both unloaded and air-sprung loaded conditions, along with the air spring bracket positioning, contribute to easier installation and improved suspension stability.

These features, combined with the square spring design, help reduce component wear and extend the product’s service life. As a result, the square spring disc axle is a suitable choice for trucks and trailers that require high safety, long durability, and reliable performance under heavy-duty operating conditions.
