* 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 NLGI No. 2 or No. 3 ball bearing grease having rust inhibitors, antioxidant
additives and a minimum viscosity of 500 SSU at 100°F (38°C). Some examples of grease having these
properties are:
Shell Alvania RL 2
Mobil Mobilith SHC220
Exxon Ronex MP
Lubricate bearings prior to extended shutdown or storage and rotate shaft monthly to aid corrosion
protection.
