Sleeve Bearings
Oil Changing
The oil reservoirs of the self lubricated bearings should be drained and refilled every 6
months. More frequent changes may be needed if severe oil discoloration or contamination
occurs. In conditions where contamination does occur, it may be advisable to flush the reservoir
with kerosene to remove any sediment before new oil is added. Proper care must be taken to
thoroughly drain the reservoir of the flushing material before refilling with the new oil.
Refill the reservoir to the center of the oil sight glass with a rust and oxidation inhibited,
turbine grade oil. The viscosity of the oil must be 32 ISO (150 SSU) at 100 F (37.7 C). Oil
capacity in each of the 2 bearings is 0.6 gal. (2 l) per bearing. Use of Carrier Oil Specification
PP16-0 is approved (Mobil DTE Light or Sun Oil SUNVIS 916).
Disassembly
The bearing sleeve is of the spherically seated, self-aligning type. The opposite drive end
bearing is normally insulated for larger motors (or when specified). On some motors, the
insulation is bonded to the spherical seat of the bearing housing. Use extreme care when
removing the sleeve from the insulated support to avoid damaging this insulation.
Note that some bolts and tapped holes associated with the bearing housings, bearing
sleeves, and seals are metric.
