This insert ball bearing carries radial load through a spherical outer ring surface, allowing angular misalignment between shaft and housing. Bore diameter is 90.0 mm, outside diameter 160.0 mm, width 52.0 mm, and net mass is 3.57 kg. The bearing is designated GE90-XL-KRR-B and features KRR sealing, which protects the bearing interior from contamination while retaining grease within the bearing. The KRR seal design supports grease lubrication and reduces the need for frequent maintenance intervals, making the bearing suitable for mounting positions where shaft deflection or housing misalignment must be accommodated. The spherical outer ring geometry compensates for angular deviation without transmitting additional stress to the bearing seat, and the sealing arrangement maintains lubricant retention throughout operation.
