Safety & Bearing Lubrication Instructions
*Suggested lubrication interval under ideal continuous operating conditions. Relubricate
while running, if safety permits, until some purging occurs at seals. Adjust lubrication
frequency depending on conditions of purged grease. Use one-half of listed interval for
vertical shaft applications or for 24 hour operation. Hours of operation, temperature and
surrounding conditions will affect the relubrication frequency required.
1. Lubricate with a high quality NLGI No. 2 lithium-base grease having rust inhibitors and
antioxidant additives, and a minimum oil viscosity of 500 SUS at 100°F (38°C). Some
greases having these properties are:
Shell - Gadus S2 V100 2 Mobil - Ronex MP
Mobil - Mobilith SHC100 Mobil - Mobilith SHC220
2. Lubricate bearings prior to extended shutdown or storage and rotate shaft
monthly to aid corrosion protection.
3. Any lubrication requirements noted on the general assembly drawing supersede
requirements found here.

*Suggested lubrication interval under ideal continuous operating conditions. Remove
bearing cap and observe condition of used grease after lubricating. Adjust lubrication
frequency as needed. Use one-half of listed interval for vertical shaft applications or
for 24 hour operation. Hours of operation, temperature, and surrounding conditions
will affect the relubrication frequency required. Clean and repack bearings annually.
Remove old grease, pack bearing full and fill housing reservoir on both sides of
bearings to bottom of shaft.

2. Lubricate bearings prior to extended shutdown or storage and rotate shaft
monthly to aid corrosion protection.
3. Purge or remove old grease when changing lubrication brands or types.
4. Any lubrication requirements noted on the general assembly drawing supersede
requirements found here.
Static Oil Lubrication
1. Use only high quality mineral oil with a VG grade indicated on the customer
submittal drawing.
2. Static oil level should be at the center of the lower-most roller. (Do not overfill.)
3. Complete lubrication change should be made annually.
