-
Standard
Service - 8 hours per day. Normal to light loading.
Maximum ambient temperature 100 deg. F
-
Severe
Service - 24 hours per day. Shock loadings, vibration
or in dirt and dust. Ambient temperature 100 to 150 deg. F
-
Extreme
Service - 24 hours a day. Heavy shock, vibration
or much dirt and dust. Ambient temperature 100 to 150 deg.
F
For roller bearing applications, divide
the lubrication period by three.
Follow
the relubrication instructions on the motor. Should no
motor-mounted instructions exist, follow these directions:
-
Lubricate
motor while it is warm and the power is off.
-
Wipe
the grease fittings clean.
-
Free
the relief valve hose of any hard grease.
-
Add grease
with a low pressure gun.
-
Start
motor and run for 30 minutes

** This is an estimated guide. If
grease is observed coming out anywhere, stop the greasing process.
Bearings will typically run hotter until grease has purged from
the bearing cavity. |
