Reduce Downtime with NN3052K High Precision Double Row Cylindrical Roller Bearing

Industrial machinery operators know the frustration of unexpected downtime caused by bearing failures. When precision components like machine tool spindles or reducer gears fail, production stops, maintenance costs rise, and deadlines slip. Sourcing reliable high precision bearings often means navigating minimum order quantities that delay urgent repairs or compromising on quality to meet tight timelines.

Engineered for Reliable Performance in Critical Applications

The NN3052K cylindrical roller bearing addresses these challenges with its robust design and flexible supply options. As an integrated manufacturer with full R&D capabilities and ISO9001 certification, we ensure consistent quality across every unit. Our separated structure allows for easy installation and maintenance, while the P0-P4 precision ratings meet the demands of high-precision industrial machinery. Whether your application requires standard specifications or custom modifications through our OEM/ODM service, this bearing delivers the performance you need without unnecessary delays.

Optimized for Heavy-Duty Industrial Environments

Designed as a radial bearing, the NN3052K excels in applications承受 heavy radial loads at moderate speeds, such as machine tool spindles and industrial reducers. Its double row construction provides enhanced rigidity and load-carrying capacity compared to single row alternatives, making it ideal for precision equipment where stability is critical. The open seal design allows for flexible lubrication options—oil, grease, or dry running—adapting to various operating conditions while maintaining performance integrity.

Precision Parameters That Drive Machinery Performance

The technical specifications of the NN3052K directly impact its operational capabilities. With precision ratings from P0 up to P4, this bearing meets strict tolerance requirements for runout and dimensional accuracy, ensuring minimal vibration and noise in high-speed applications. The V1-V4 vibration grades further enhance its suitability for precision machinery where smooth operation is essential. Measuring 260*400*104 mm, the bearing’s dimensions balance load capacity with space efficiency, making it compatible with a range of industrial equipment designs. Constructed from high-quality bearing steel, it delivers the durability needed to withstand continuous operation in demanding industrial environments.

Long-Term Value Through Quality Engineering

Opting for quality bearings like the NN3052K reduces total cost of ownership by minimizing premature failures and unplanned maintenance. Inferior bearings often fail early, leading to costly production interruptions and potential damage to adjacent components. Our commitment to quality—backed by ISO9001 and ISO14001 certifications—ensures each bearing meets rigorous performance standards. With a 12-month global warranty and defect replacement policy, we stand behind the reliability of our products, providing peace of mind that extends beyond the initial purchase.
