Cylindrical roller bearings

Separable high-capacity cylindrical roller bearings support high-speed shafts in wind-turbine gearboxes. The bearings have high load-carrying capacity and eliminate risks of rollerto- roller smearing and adhesive wear. Full dimensional exchangeability with standard counterparts lets them fit existing design envelopes whether for initial designs or replacement upgrades.

Key features and benefits include a lightweight brass cage that promotes lower inertia to reduce the risk of roller smearing; integrated cage guidance on the inner ring (shoulder) reduces roller slip, risk of smearing, and improves reliability; optimized play between rollers and cage bars provides greater safety and reliability; and black-oxidized rollers improve both running behavior and oilfilm buildup.

The bearing’s separable design promotes quick and easy mounting/dismounting for reduced operating, maintenance, and lifetime costs per kilowatt hour.
