Frequently Asked Questions
WEG Motor Polyrex Electric Motor Grease
▶️ Question: Is this grease intended for compressor motor bearings?
Answer: It can be used in compressor motor bearings when the motor/bearing documentation specifies it. Always match the grease type to the motor OEM recommendation.
▶️ Question: How much grease should I apply?
Answer: Use the amount specified by the motor manufacturer. Over-greasing can raise bearing temperatures and cause premature failure.
▶️ Question: Can I mix this grease with another grease already in the bearing?
Answer: Mixing greases can cause incompatibility issues. If you’re changing grease types, follow the OEM guidance for purging and relubrication.
▶️ Question: How do I know when to re-grease?
Answer: Follow your preventive maintenance schedule. Temperature, duty cycle, and contamination exposure can shorten intervals.
▶️ Question: What are signs of lubrication-related bearing problems?
Answer: Common signs include elevated temperature, unusual noise, vibration changes, or increased motor load. Address promptly to avoid downtime.
