Is the used trailer axle safe to use?

Trailer axle is one of the power core assembly of semi-trailer, its main role is to carry the body weight, followed by driving and braking, to maintain the normal running of the vehicle on the road. It can be said that the safety and reliability of a trailer largely depend on the quality of its axles.

With the continuous development of the domestic transportation industry, the trailer axle industry chain is becoming more and more perfect. In addition to more and more new products, the second-hand market also began to appear the axle figure.

Some sellers claim that their used trailer axles come from big brand manufacturers and are of reliable quality. Even if they are used products, they can be much higher than ordinary new products in terms of performance. Compared with new products, these used axles occupy an advantage in price, coupled with the brand, so that some owners are very tempted.

So is this used axle really reliable?

The axle is a key component of the chassis of the vehicle, and it is also a consumable component. In addition to bearing the key performance of the vehicle such as load and braking, it is also subjected to various erosion from the road surface, such as pothole road, waterways, silt road, up and down mountain road, and salted road surface after snow. Even temperature, humidity, vehicle vibration and other factors will cause different degrees of loss. The performance of even the best axles will degrade to varying degrees, unless the previous owner's vehicle really wasn't used much. However, the use of second-hand axles before sale, to a large extent, can only be learned through the seller's description, as for the true degree of play is not discounted, it is necessary to analyze the specific problem. But anyway, those hidden in the naked eye loss, for the subsequent use of used axles, will be a great impact. Light will affect the vehicle attendance rate, heavy may cause safety accidents. Therefore, in order to save money to buy a used axle, but not worth the loss.

Moreover, there are many axle brands on the market now, some of which have good performance and reasonable price products. It is better to pay attention to the selection of new products than to buy second-hand axle whose performance is uncertain. For example, the axle produced by DARO Group Co., Ltd. is a representative product of high cost performance. Its raw material is made of 20Mn2 high-strength alloy seamless steel pipe, which is completed after more than ten processes. It improves the strength and toughness of the axle, and avoids deformation and bending during high-strength transportation, greatly enhancing the bearing capacity, wear resistance and fatigue resistance. With reliable quality and approachable price has won wide praise from users at home and abroad.
