How to determine if there is minor damage to the lip of the bearing seal of FAF67D100M4/61.07/M1/0 reducer

To determine if there is any minor damage to the lip of the bearing seal of the FAF67D100M4/61.07/M1/0 reducer, the following steps can be followed:

1、 Appearance inspection

Observing the lips: Carefully inspect the lips with a magnifying glass or endoscope for cracks, burrs, or localized wear.

Check the sealing surface: Confirm whether the sealing surface is evenly adhered, whether there are any burrs or unilateral wear.

2、 Running status monitoring

Listen to the sound: If there is a hissing or periodic friction sound during operation, it may be due to lip damage causing dry friction.

Temperature measurement: Use an infrared thermometer to measure the lip temperature. If the temperature rise is significantly higher than normal operating conditions, poor lubrication may be caused by damage.

3、 Dynamic verification

No load test run: Run the gearbox without load and observe whether there is oil leakage at the shaft end. If the oil stain spreads along the axis, it may be a lip damage.

Low pressure test: If necessary, perform a low-pressure airtight or hydraulic pressure holding test to confirm the reliability of the seal.

4、 Professional tool assistance

Vibration analysis: Collect data using a vibration detector. If there is a sudden increase in high-frequency components, it may indicate lip abnormalities.

Oil analysis: Regularly sample and test lubricating oil. If the concentration of metal particles increases abnormally, it may be caused by lip wear.
