DTR-T TYPE EXTERNAL TEETH

DTR-T slewing bearings are specifically equipped with features essential for supporting the main cutter of a tunnel boring machine. These include high shock resistance to withstand sudden impacts, a high load rating to handle heavy loads, and superior sealing performance to protect against contaminants and ensure reliable operation in challenging tunneling environments. The bearings' design incorporates a triple-row compound cylindrical roller bearing structure, optimizing load distribution and operational stability. This makes DTR-T slewing bearings ideal for critical applications where precision, durability, and performance under extreme conditions are essential requirements.
