Separable High-Capacity Cylindrical Roller Bearings support high-speed shafts and high-speed intermediate shafts in wind turbine gearboxes. These reliable bearings have a higher load-carrying capacity and eliminate risks of roller-to-roller smearing and adhesive wear in service. Exchangeability with standard counterparts allows fitting them to existing design envelopes whether in initial designs or replacement upgrades.
The compact bearing combines and builds on the advantages of conventional and SKF High-Capacity Roller Bearings. Key features and benefits include a lightweight brass cage to promote lower inertia to reduce the risk of roller smearing, cage guidance on the inner ring (shoulder) contributes to reduced roller slip, reduced risk of smearing, and higher reliability. In addition, the right amount of play between rollers and cage bars provide greater safety and reliability, and black-oxidized rollers improve running behavior and oil-film buildup for more stable running conditions.
During maintenance, especially up tower, the separable design promotes quick and easy dismounting and mounting to help reduce operating, maintenance, and lifetime costs/kWh.
