Domestic trailer axle manufacturers are now keen to promote their own maintenance free axle, known as 50W km or 30W km maintenance free axle. However, in the suggestions for car purchase and use, the axle is maintained according to the conventional maintenance method. At present, maintenance free axles have been launched in China.

Many friends think that maintenance free axles do not need maintenance. In fact, this idea is wrong. In recent years, many manufacturers have focused on maintenance free, and some friends may have been misled by the manufacturers' overwhelming publicity.

The maintenance free axle only has a longer maintenance cycle, which can effectively improve the operation efficiency of the vehicles of the transportation company.

Difference between maintenance and service

The so-called maintenance is the routine inspection of disassembly. After a period of time or mileage, even before the maintenance cycle, you need to open it to see the operation status. This is called maintenance. Maintenance refers to the routine maintenance of mechanical parts after a certain time or mileage, and the replacement of lubricating grease and wiping required are called maintenance.

Technology of maintenance free axle

Maintenance free axle is to replace the ordinary bearing used by the previous axle with a special bearing with better manufacturing technology. Such bearing is equipped with grease, which can directly increase the maintenance cycle of trailer axle from the previous 5W km to 30W or 50W km, greatly improve the transportation efficiency of vehicles and save a lot of vehicle maintenance costs.

Although the axle maintenance cycle with better bearings is longer, many manufacturers still suggest that drivers check the axle more before the trailer reaches the theoretical maintenance cycle. It is best to maintain it once. Because the domestic road transportation environment is complex, the road conditions in many places are relatively bad, or there are many heavy-duty trailers, and the trailer axle load is relatively large, which is quite different from the theoretical transportation environment, it is recommended that drivers check more and maintain in advance.

Reminder: due to the different road conditions and driving habits of our trailers, the maintenance free axle can not be really free when the manufacturer publicizes it. For heavy-duty machinery, machine wear is inevitable, so we should check and maintain the axle regularly, cultivate good driving habits, and ensure our driving safety.
