3211-BD-XL-2Z FAG Double Row Angular Contact Ball Bearing 55mm x 100mm x 33.3mm
3211-BD-XL-2Z FAG Double Row Angular Contact Ball Bearing
The 3211-BD-XL-2Z FAG Double Row Angular Contact Ball Bearing is a precision-engineered bearing designed to handle simultaneous radial and axial loads in both directions. This robust bearing combines FAG's renowned engineering excellence with advanced design features, making it ideal for demanding industrial applications requiring superior load-carrying capacity, reliability, and protected operation in challenging environments.
Design & Construction
Double row angular contact bearings feature precisely displaced raceways in both inner and outer rings, enabling exceptional handling of combined loads acting in multiple directions. This dual-row configuration provides a stiff bearing arrangement with excellent load distribution, while also delivering superior tilting moment capability. The sheet steel cage construction ensures robust operation with reliable performance consistency, while the covers on both sides protect the bearing from contamination and provide integrated sealing protection.
The 30° contact angle geometry has been specifically optimized for balanced axial and radial load distribution, making this bearing exceptionally versatile for applications subject to complex loading conditions. The normal radial clearance provides operational flexibility for varying load conditions and thermal expansion.
