leaf spring kits for trailers

Specification: 26*90
Material: SUP9
This leaf spring has 11 leaves, wherein the fifth to the eleventh leaves feature short tapers and chamfers at both ends, and the theoretical total weight of the leaf spring is 217.83 kg.
The leaf spring 5001854879-00-11L is made from SUP9, additionally, with the tempered hardness of HBW 375-444, the leaf spring has the anti-fatigue life longer than those of other leaf springs.
By means of short tapers + chamfers at both ends of each of the fifth to the eleventh leaves, the weight of the leaf spring is lowered, and thus the fuel consumption of a vehicle on which the spring is assembled is lowered.
With an assembled structure of a uniform central hole + bolt, a single leaf of this leaf spring can be replaced separately when it is broken, thereby lowering the repair cost.
Graphite lubricating grease is smeared between spring leaves of the assembly, which can not only reduce friction between the spring leaves, but also prevent pollution, thereby prolonging the service life of the leaf spring.
Automated production lines are adopted for rolling, thermal treatment and shot blasting of the leaf spring, which can guarantee the stability and consistency of the leaf spring, and reducing personal errors.
Compared with a guide arm, the leaf spring 5001854879-00-11L seems to be more reliable under overloaded (e.g., an axle load of a mine truck is 50 tons or above), high-temperature (e.g., the Middle-East market) or insufficient-maintenance (e.g., the Africa market) conditions and the like.
The leaf spring 5001854879-00-11L is simple in structure, a single leaf thereof can be directly replaced in a repair shop, whereas an air suspension of the guide arm requires professional air sac repair, and thus the leaf spring 5001854879-00-11L has prominent advantages in the markets of developing countries.
