Product description

Designed for the heavy-duty Eurovac DR8 and DR858 series 10 HP blowers, the NTN 6309LLB3 drive-end bearing is built to handle the significant mechanical forces of a large-scale industrial vacuum system. These regenerative blowers move substantial air volumes, placing continuous radial and axial loads on the motor bearings. The 6309 series offers a substantial bore and outer diameter to accommodate the larger shafts of 10 HP motors, providing a stable foundation for the high-speed impeller. With NTN's advanced LLB sealing technology, this bearing provides a dependable barrier against the grit and debris common in extraction environments, ensuring that the internal grease remains pure and effective. Replacing a worn bearing with this high-quality NTN component prevents costly motor damage and maintains the consistent performance required for industrial air management.
