MAINTENANCE
10.6 PILLOW BLOCKS
LE model ERVs use pillow block bearings to support the fan shaft. Maintenance requirements for pillow
blocks depend on a combination of shaft size and shaft RPMs. The fan shaft diameter is typically 1.44
inches.
To grease pillow blocks, the fan should be at normal operating speed and temperature prior to greasing.
• The recommended interval for greasing of pillow block bearings is 3 - 6 months, based on 1,000
to 2,000 hours of operation.
• The recommended grease is Mobil Polyrex. If Mobil Polyrex is not available, use an NGLI#2 grease
that is compatible with a lithium thickener, mineral base oil and a temperature range of -10 to +
260 degrees F.
• The recommended amount of grease is 2 grams.
• Clean the grease fitting (zerk) before attaching the grease gun.
• Grease slowly and stop when the first sign of grease seepage from the bearing’s seals is observed.
• Leave a small amount of grease on the zerk as a protective coating.
• In all cases, Industry Best Practices should be observed. Maintain a record of every lubrication
and the type of lubricant used.
