Panaflo’ s unique hydrowave bearing (HWB) addresses the traditional weakness of sleeve bearings…axial fric-
tion. By utilizing our unique HWB system, the thrust plate “floats” on a circulating film of oil, which greatly
reduces the axial friction and the bearing’ s deterioration. The HWB pattern on the bearing virtually eliminates
thrust plate contact which is depicted above.
As the shaft rotates it acts as a pump constantly circulating the oil in the radial, as well as the axial direction.
The sealed system and reservoirs of oil maintain the proper lubrication to minimize mechanical contact and
prolong the fan’ s life expectancy. The radial direction analysis shown above is essentially the same as a tradi-
tional sleeve bearing. Panasonic’ s unique HWB reduces the axial contact.
