Main application fields of QIBR spherical-roller hybrid slewing bearing RD 700 series:

Wind Power Generation:

The RD 700 Series can withstand the significant radial and axial loads generated during the operation of wind turbines, ensuring long-term stable operation at high loads and low speeds.

Mining Machinery:

Mining equipment often operates under high loads and harsh conditions. The RD 700 series has been widely used in the rotating parts of such machinery due to its high load-carrying capacity and adaptability,.

Port Lifting Equipment:

Port handling machinery (such as container cranes, ship cranes, etc.): These machines require rapid rotation and must handle strong torque from loads. The structural design of the RD 700 Series can manage these high loads and dynamic loads simultaneously so that ensures the stability during the handling process.
