ball bearing / axial / angular-contact / double-row
SKF Precision Bearings
axial, angular-contact, double-row
high-speed, combined, high-rigidity, for heavy loads, with lubricant
Bearings in the BTW series (fig. 1) 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.
