Developed to customer specifications, Modular Bearing Systems consist of cylindrical roller bearings that are fitted directly into planetary gear in wind turbine gearboxes. Bore of gear acts as outer raceway, so that bearings themselves do not have outer ring. Available in bore diameters of 160, 190, and 200 mm, bearings have inner race-guided one-piece brass cage, which contains inspection grooves for endoscopic condition assessment of inner race surface.
