Angular contact thrust bearings for improved performance
The BTW series high-speed angular contact thrust ball bearings represent a radical departure from the former 2344 (00) series bearing design. BTW series bearings consist of two separate angular contact thrust ball bearings arranged back-to-back to accommodate thrust loads in both directions. The new design without a spacer sleeve makes mounting faster, easier and more accurate. This new series of bearings is designed to better meet the load, speed and stiffness requirements of modern machine tools.
The BTM series of bearings have been re-designed to accommodate higher speeds, from 6% to 12% depending on the size. These bearings are dimensionally and functionally interchangeable with the previous BTM series. The range has been expanded to accommodate shaft diameters from 60 to 180 mm. The new BTM bearing design minimizes heat generation even at higher speeds and provides high load carrying capacity, while maintaining a high degree of system rigidity.
