Main shaft bearing for wind turbine

The main shaft bearings are generally spherical roller bearings, and there are also double-row tapered roller bearings with large taper angles. Most impeller main shafts are supported by two spherical roller bearings. Because the load on the main shaft of the impeller is very large, and the shaft is very long and easily deformed, the main shaft bearing must have good self-aligning performance, high impact resistance and wear resistance.

Working conditions of main shaft bearing: low speed (<25rpm), wide temperature range, heavy load, vibration, high humidity.

Grease requirements of main shaft bearing: excellent wear resistance, good oxidation stability, excellent low temperature bearing start-up performance, good water resistance and so on.
