MAINTENANCE
Ensure bearing set screws and collars are torqued to the correct specifications upon installation and every scheduled maintenance
thereafter. Never mix lubricants or greases while re-greasing bearings; check bearing specifications for the correct grease
recommended by the manufacturer.
• Lubrication intervals depend on many factors such as temperature, moisture, or dirt. Consult a local PennBarry representative
for lubrication recommendations.
• Lubricant should be selected based on the bearing manufacturer specifications.
• If the unit is stored for longer than a month, rotation of the shaft is recommended to free up grease in the bearing.
* Lubrication interval is based on 12 hour per day operation and maximum 160°F. housing temperature. For 24 hour per day
operation, the interval should be cut in half.
** Lubricant should be added with the shaft rotating and until clean grease is seen purging from the bearing. The lubrication interval
may be modified based on the condition of the purged grease. If bearing is not visible to observe purged grease, lubricate with
number of shots indicated for bore size.
