Main shaft sliding bearing
Simulation driven design - combining EHD with shaft dynamics
Segmented radial tile and thrust box design
Tower replacement and full lifecycle cost reduction
Facing deep sea and ultra large megawatt units
Intelligent bearing integrated solution
Sliding bearings have more significant advantages in the large-scale and far-reaching upgrading of the unit. Avoiding the difficulty of quenching heat treatment technology that increases with the geometric level as the size increases. Replacing bearings on the tower can save on lifting costs, especially the expensive cost of lifting ships for offshore units.
Hengchang sliding main bearings are designed in a block and modular manner, making the shaft system design of the unit more open and free;
The PAEK modified material developed provides higher wear resistance and oil deficient self-lubricating performance;
The unique multi-layer composite structure enhances the load-bearing and reliability of the structure.
