BTW 85 CTN9/SPW33 SKF Angular contact ball bearing

Bearings in the BTW series consist of two single row angular contact thrust ball bearings with a 60° contact angle, arranged back-to-back. This configuration, combined with the large number of balls, enables these bearings to accommodate high axial loads in both directions and provides a high degree of system rigidity. Bearings in the BTW series are separable. When the shaft washers are pressed together, preload within a predetermined range will result.
