3313-BD-XL FAG Angular Contact Ball Bearing 65mm x 140mm x 58.7mm
3313-BD-XL FAG Double Row Angular Contact Ball Bearing
Premium double row angular contact ball bearing engineered for high-speed precision applications requiring simultaneous radial and axial load capacity. This FAG bearing delivers exceptional performance and reliability for demanding industrial equipment where robust load handling and precision are critical. The double row configuration provides superior axial load capacity in both directions compared to single row bearings, making it an ideal choice for applications demanding enhanced load distribution and rotational accuracy.
Design & Functionality
Double row angular contact ball bearings are specifically designed to accommodate combined loads—both radial and axial forces acting simultaneously. The 30-degree contact angle on this bearing offers optimized load distribution and performance, enabling efficient handling of axial loads in both directions with exceptional precision. The open bearing design provides flexibility in lubrication methods and maintenance strategies, allowing for custom lubrication approaches suited to specific application requirements. The standard version configuration ensures compatibility with a wide range of industrial mounting scenarios.
