Bearings Products: Stacked-Plate Bearings
Hydrodynamic pressure bearings in the BBSPLN Series are 30% lighter and cost less than conventional ball bearings.
They consist of a stack of
0.4-mm-thick aluminum-silicon alloy
plates housed in a stainless-steel
case. The inner faces of the plates
form the bearing’s bore to an accuracy
of ±0.003 mm. Cutouts in the
plates house a polyurea-thickened
grease with antioxidant and anticorrosion
additives.
The bearings handle speeds of up
to 20,000 rpm in light-duty applications
like compact fan motors and
printer-paper feeders. Radial loads
of up to 1 kg are tolerated. IDs range
from 1 to 6 mm.
