Figure 34. Measuring Bearing Unmounted Clearance (bridge for 42" machine shown)
5. Try to pull the gauge straight out. If it comes out, increase the size of the gauge by .001". If it
does not come out, decrease the gauge by .001". The thickest feeler gauge that will come out
is the unmounted internal clearance of the bearing.
6. Compare the measured clearance with the “Unmounted Clearance” in Table 24: Table of
Bearing Clearances, page 82 . If the measured clearance is not within the range shown, do not
use the bearing. Contact your bearing supplier for an exchange.
NOTE: The clearances listed in the chart are industry standards and therefore apply
to all brands of bearings supplied by Milnor ® . If other sources of bearings are used, re-
fer to the manufacturer’s instructions for proper clearances.
NOTE:
To locate your bearing on the chart, match the first five characters of the
manufacturer’s part number (
not the
Milnor ®
part number
) with those in the chart.
For example, for a manufacturer’s part number 22217LBK, find under “Manufacturer
Part Number” the line “22217 . . .”
