Installation Instruction for OilLess
Bearings
In most cases, OilLess Bearings are used with a
press fit in the same manner as general sleeve Bearings. Fit the
Bearings into housings using mandrels or press. In case of a
relatively large interference, provide both the ID of the housing
and the OD of the Bearing with chamfers, and fit the Bearing into
the housing with mandrel for easy installation.
Break-in
Instruction for OilLess Bearings
At the on start of the operations, contact
surfaces of shafts and Bearing are smooth, however, microscopic
irregularities are inevitable to develop after continued use. A
deviation from true center alignment may also exist. Thus the
initial contact between sliding surfaces could be
local.
Do not immediately start a regular loaded
operation. It may result in damaging the bearing surfaces, leading
to a shorter service life. Instead, gradually break-in operations so
to smooth out the microscopic irregularities, and allow the entire
pressure support area to slowly come in contact without causing
damage. This is called a “break-in for
familiarity”.
