What to do if there is no oil flow or oil flow is too low in SEW-Eurodrive Industrial Equipment?
- S
  Susan BaileyAug 13, 2025
  If you notice no oil flow or that the oil flow is too low in your SEW-Eurodrive Industrial Equipment, several factors could be at play. First, ensure the rotating direction is correct and properly connected. Also, check that the motor is running as expected. Another possibility is a blocked oil circuit; make sure all stopping valves are open. Finally, high suction pressure could be the culprit; select a suction pipe/hose that is adequately wide and reduce the suction height.

Why is the operating temperature too high in my SEW-Eurodrive X Series?
- E
  Erica MooreAug 17, 2025
  High operating temperatures in SEW-Eurodrive Industrial Equipment can stem from several causes. It could be due to excessive or old oil, or heavily contaminated oil, requiring you to check the oil level and change the oil if needed, and analyze the oil to determine the cause. High ambient temperatures can also be a factor, so protect the gear unit from external heat. For gear units with a fan, ensure the air intake openings and gear unit housing are clean. If equipped with an oil-air or oil-water cooling system, consult its operating instructions. For units with built-in cooling, verify the cooling liquid flow rate, entry temperature, and clean the cooling system if there are deposits.

How to troubleshoot unusual, regular running noise in SEW-Eurodrive Industrial Equipment?
- S
  Scott ZimmermanAug 20, 2025
  Unusual, regular running noises in SEW-Eurodrive Industrial Equipment can arise from several issues. A meshing or grinding noise may indicate bearing damage, suggesting a need to check the oil consistency and change the bearings. A knocking noise could point to an irregularity in the gearing, in which case you should consult SEW-EURODRIVE and provide an audio recording. Deformation of the housing upon tightening can also cause noise, requiring you to check the gear unit mounting. Insufficient rigidity of the gear unit foundation may also generate noise, suggesting that you reinforce the foundation.
