5.3 Motor bearing grease lubrication
Electric motor are pre-lubricated from factory and do not require additional lubrication at start-up. Motors
without external grease nipples have sealed bearing that cannot be re-lubricated.
Motors with grease nipples should only be lubricated with approved types of grease. Do not over-grease
the bearings. Over-greasing will cause increased bearing heat and can result in bearing or motor failure.
Do not mix oil-based grease and silicon grease in motor bearings.
Bearing grease will lose its lubricating ability over time.
The lubricating ability of a grease depends primary on the type of grease, the size of bearings, the speed
at which the bearings operate and the severity of the operation condition.
Good result can be obtained if the following recommendations are used in your maintenance program. It
should also be noted that multistage pumps, pumps running to the left of the performance curve, and
certain pump ranges may have higher thrust loads. Pumps with high thrust loads should be greased
according to the next service interval level.
Caution
The grease outlet plug must be removed before adding new grease.
<<Grease lubricating procedure>>
Caution
Keep grease free from dirt to avoid damage to motor bearings. If the
environment is extremely dirty, contact TERAL for additional information.
Do not mix dissimilar of grease.
1. Clean all grease nipples. If the motor does not have grease nipples, the bearing is sealed and
cannot be greased externally.
2. If the motor is equipped with a grease outlet plug, remove it. This will allow the old grease to be
displaced by the new grease. If the motor is stopped, add the recommended amount of grease. If
the motor is to be lubricated while running, add a slightly greater quantity of grease.
3. Add grease slowly taking approximately one minute until new grease appears at the shaft hole in
the flange or grease outlet plug. Never add more than 1/2 times the amount of grease shown in the
re-lubricating chart.
Note
If the new grease does not appear at the shaft hole or grease outlet, the
outlet passage may be blocked. Contact TERAL.
4. Let motors equipped with a grease outlet plug run for 20 minutes before replacing the plug.
