Does the FAF47-36.34-1.5KW gear reducer seal need to be run-in after replacement?

After replacing the seals of the FAF47-36.34-1.5KW gear reducer, it is recommended to perform a moderate running-in operation to ensure the stability of the cooperation between the sealing system and the moving parts and reduce the risk of leakage.

Although the main purpose of running-in is usually for transmission components such as gear pairs and bearings, after the seal is replaced, the surface contact state between the seal ring and the shaft changes, resulting in microscopic misfit. Short-term low-load operation can help the seal gradually adapt to the rotation state of the shaft and improve the sealing effect, which is especially critical under high temperature, high humidity or vibration conditions.

Operational suggestions during the running-in period:

‌1. Control load‌ : It is recommended that the working load during the running-in period should not exceed 85% of the rated load to avoid micro-deformation of the shaft or uneven sealing compression due to overload.

‌2. Monitor temperature rise and leakage‌ : Check the box temperature and sealing area for oil leakage every 30 minutes in the early stage of operation. If there is abnormal temperature rise or oil dripping, stop the machine immediately for investigation.

‌3. Check the status of the lubricating oil : Impurities or air are easily mixed in after the seal is replaced. The oil level and quality need to be checked frequently, and the lubricating oil should be replenished or replaced if necessary.

‌4. Running time‌ : It is generally recommended to run continuously for 2 to 4 hours with no load or light load as the initial running-in, and then gradually load to normal operating conditions.

‌5. Machine maintenance follow-up‌ : After the running-in is completed, a comprehensive inspection should be carried out, including tightening the connecting parts, replacing the grease (if necessary), and confirming whether the sealing pressure is up to standard.
