Thrust ball bearings are comprised of a spinning ring of (bearing) balls in between two washers. They're ideal for low-thrust, low-axial load applications.
Needle roller thrust bearings consist of small cylinders (Needles) aligned with their axes pointing to the center of the bearing. Our metric needle roller thrust bearings are available in widths from 2 mm to 5 mm. We also stock axial thrust washers that fit these bearings. A wide range selection of inner and outer ring spacers are also available.
