SP-DTR-T EXTERNAL TEETH

When DTR-T slewing bearings are used with forced circulation lubrication, they are equipped with an oil inlet and an oil drain port. This configuration ensures efficient lubrication throughout the bearing's operation, maintaining optimal performance and extending its service life. The oil inlet allows for the introduction of lubricant into the bearing system, ensuring that all components receive adequate lubrication to reduce friction and wear. Meanwhile, the oil drain port facilitates the removal of used lubricant and contaminants, helping to maintain cleanliness and prevent buildup that could impair bearing function. This feature is particularly beneficial in heavy-duty applications such as those involving tunnel boring machines, where reliable and consistent lubrication is crucial for continuous and safe operation under demanding conditions.
