WARNING
1. This equipment must not be operated without proper guarding of
all moving parts. While performing maintenance be sure remote
power switches are locked off. See installation manual for recom-
mended safety practices.
2. Before starting: Check all setscrews for tightness, and rotate wheel
by hand to make sure it has not moved in transit.
*Suggested lubrication interval under ideal continuous operating condi-
tions. 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 annu-
ally. Remove old grease, pack bearing full and fill housing reservoir
on both sides of bearings to bottom of shaft.
1. Lubricate with a high quality NLGI No. 2 lithium-base grease hav-
ing 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 Exxon - 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. Purge or remove old grease when changing lubrication brands or
types.
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.
