The 5 Bearings That Keep Wind Turbines Turning
Mainly for use in generators, deep groove ball bearings are well suited for medium high radial and axial loads in one or both directions. They have numerous clearance and tolerance classes available for different operating
The 5 Bearings That Keep Wind Turbines Turning
Wind turbine manufacturers typically cover equipment with a maximum warranty coverage of 10 years. Once the warranty period has passed, bearings are almost always near the top of the list of necessary repairs. If

Demand for offshore wind power generation is expected to increase in the future. We will improve "bearing maintenance" issues faced by generator manufacturers. Can be disassembled into
6 FAQs about [Generator bearing replacement for wind power]
What is a main bearing for a wind turbine?
the Creative Commons Attribution 4.0 License. This paper presents a review of existing theory and practice relating to main bearings for wind turbines. The main bearing performs the critical role of supporting the turbine rotor, with replacements typically requiring its complete removal.
How many bearings are in a wind turbine?
A typical wind turbine consists of more than a dozen bearings that are expected to work simultaneously and continuously for many years. As a result, wind turbine bearings and gearboxes are often susceptible to failure well before their designed service lives.
What is a bearing failure in a wind turbine?
Bearing failures in wind turbines are a major cause of downtime in energy production for unplanned maintenance, repairs and replacements. This failure type is a primary cost and results in higher operations and maintenance (O&M) costs for the energy operator and in higher utility bills for the customer.
Do wind turbine bearings need to be repaired?
Once the warranty period has passed, bearings are almost always near the top of the list of necessary repairs. Wind turbine components have high operating demands and a large part of their efficiency is dependent on the reliability of the bearings used in the application.
Can custom bearings upgrade wind-turbine generators without redesigning them?
The bearings can supposedly upgrade existing wind-turbine generators without redesigning them. Custom bearing may be a solution where conventional designs have come up short. Products of several bearing manufacturers support pitch, yaw, and gearbox applications in systems from 200 kW to 5.0 MW.
What are the operating conditions and loading of wind turbine main bearings?
The operational conditions and loading for wind turbine main bearings deviate significantly from those of more conventional power plants and other bearings present in the wind turbine power train, i.e. those in the gearbox and generator.
