In the suspension system section, this axle is designed with an E distance of 300 mm and an F distance of 130 mm. Detailed specifications, including reinforcement component thicknesses ranging from 35 to 87 mm and calculations for both unloaded and fully loaded conditions without air, ensure not only ease of installation but also stable and smooth operation.

The positioning of the air spring bracket has been precisely engineered to extend the service life of the system and minimize the need for frequent maintenance. Collectively, these features make the round spring disc axle, Type B, an ideal choice for road transport fleets operating under heavy loads and over long distances.
