* Suggested initial greasing interval. If safety permits, re-lubricate while running until some purging occurs
at seals. Adjust lubrication frequency depending on condition of purged grease. Hours of operation,
temperature and surrounding conditions will affect the re-lubrication frequency required. For 24 hour
operation double the lubrication frequency.
Lubricate with a multipurpose roller bearing NLGI No. 2 having rust inhibitors and antioxidant additives,
and a minimum oil viscosity of 500 SSU at 100°F. Some examples of grease having these properties are:
Shell
Alvania No. 2
Mobil
Mobilith AW2
Mobilith SHC100
Texaco
Premium RB2
American
Rykon Premium 2
Lubricate bearings prior to extended shutdown or storage and rotate shaft monthly to aid corrosion
protection.

* Suggested initial greasing interval. Remove bearing cap and observe condition of used grease. Adjust
lubrication frequency as needed. Hours of operation, temperature and surrounding conditions will affect
the re-lubrication frequency required. Clean and repack bearing annually. Remove old grease, pack
bearing full and fill housing reservoirs on both sides of bearing to bottom of shaft. For 24 hour operation
double the lubrication frequency.
** Grease to be added at each interval.
Lubricate with a multipurpose roller bearing NLGI No. 2 having rust inhibitors and antioxidant additives,
and a minimum oil viscosity of 500 SSU at 100°F. Some examples of grease having these properties are:
