Needle roller bearings are designed for radial load appliions where a low profile is desired. Hydrodynamic bearings are fluid film bearings that rely on a film of oil or air to create a clearance between the moving and stationary elements. Hydrodynamic pillow block bearings maintain high stiffness, load capacity, and long bearing life, but are considerably more complex and .

 · Roll balancing is the manipulation of the center of gravity so that it falls along the axis around which it must revolve. If this condition does not exist, unbalance results and the axis will tend to rotate about the center of gravity, with the journals tracing some circular orbit. The resultant unbalanced forces are detrimental to the rolls involved and to the associated .
