Forestry machinery
Forestry machinery such as logging machines and chippers often operate in harsh outdoor environments, exposed to impacts, dust, and fluctuating temperature and humidity conditions. Therefore, their bearings must exhibit exceptionally high reliability and sealing performance. In critical components like gearboxes, drive axles, and roller shafts, it is common to use self-aligning roller bearings or tapered roller bearings that can withstand heavy loads and impacts, complemented by specialized sealing and lubrication designs to cope with the demanding operating conditions characterized by high vibration and intermittent heavy loads.
Articulated bus
The articulated joint connecting the front and rear carriages of an articulated bus is its core component, requiring specialized large-sized slewing bearing units. These bearings must possess multi-directional load-carrying capability to withstand the complex torsional and shear forces generated during vehicle turns, ensuring smooth and agile turning performance. Moreover, in chassis components such as wheel hubs and gearboxes, there are also high demands on bearing precision, durability, and ease of maintenance, in order to meet the stable operational requirements of public transportation systems that operate frequently over long distances.
Artificial lift
The core requirements for artificial lifts are absolute safety and smooth operation. In critical components such as the cage’s guide wheels, drive units (including motors and gear reducers), and fall-arrest devices, bearings must exhibit high load-carrying capacity and high precision. In particular, the guide-wheel bearings must operate smoothly, generate low noise, and withstand frequent start-stop shocks. Moreover, given that these lifts are often used on construction sites, the dustproof sealing performance of the bearings is also of paramount importance.
Laser equipment
In equipment such as laser cutting and welding machines, bearings are primarily used in high-precision moving components, including laser head drive systems, galvanometric mirror systems, and rotary worktables. The core requirements for these bearings are extremely high motion accuracy, high-speed stability, and low heat generation. Typically, precision angular contact ball bearings or ceramic hybrid bearings are employed to meet the demands of minute feed rates, high-speed scanning, and long-life continuous operation, thereby preventing bearing vibration or thermal deformation from compromising machining accuracy.
