Bearing of Hoisting Equipment

Bearings for port tower crane and ship crane as well as for construction machinery belong to slewing bearing. In which, four-point contact ball slewing bearings, three-row roller slewing bearings and other oversized and heavy-duty bearings are commonly used. As general working conditions are very bad, the bearing is required to have strong environment adaptability and to be resistant to moisture, salt and wind erosion. The crane components withstand high axial loads and overturning moment and operate in harsh marine environments. Therefore, improving the safety and reliability of products is the most critical problem.

E-FINE can conduct individual design and fine processing of products. Adopting edge sealing, special oil and corrosion-resistant electroplating finish and other proprietary technologies can effectively meet the requirements of this equipment.
