Is the maintenance-free trailer bridge easy to use? How much is the maintenance-free axle?

​The axle is one of the most vital parts of the semi-trailer, which is directly related to the bearing, driving and braking of the vehicle. It is called the three core assembly of the trailer together with the engine and gearbox, and plays a decisive role in the stability and safety of the vehicle.

Maintenance free axle refers to the maintenance and maintenance cycle is relatively slow axle, typically oil lubrication instead of grease lubrication, gear oil injection in the hub unit, so that the hub and oil seal to form the storage space of gear oil, let the bearing immersed in gear oil, to ensure its full lubrication ability, in order to obtain a longer maintenance cycle.

The maintenance cycle is lengthy, the owners need to invest time, energy and thus on is reduced, the absence caused by the maintenance of the vehicle is also reduced, and the operation efficiency is naturally improved to a certain extent.

Semi Trailer Manufacturers remind us that maintenancefree axle only has longer maintenance cycle, which does not mean that maintenance is entirely unnecessary. Daily inspection and maintenance are still indispensable, especially for vehicles with elevated attendance rate, relatively bad operating conditions and lengthy distance transportation span of east, west, North and South. Even if the maintenance mileage is not reached, it is necessary to do a good job of routine inspection and maintenance of the axle, so as to completely ensure safety and give full play to the advantages of the use of the axle.
