Structural Characteristics：

Double-row Cylindrical Roller Design：The NN30K series bearings adopt a double-row cylindrical roller structure, which can bear large radial loads and is suitable for heavy-duty working conditions.
Optional Cage Materials：Cages are available in two materials, nylon and brass. The nylon cage is lightweight, has good self-lubricating and wear-resistant properties, and can reduce operation noise and friction. The brass cage has high strength and can work stably under high temperature and high load conditions.
Precision Ring Machining：The inner and outer rings are processed with high precision and heat-treated. They have high dimensional accuracy, good surface hardness and wear resistance, and fit closely with the rollers, ensuring the rotational accuracy and stability of the bearings.

Performance Advantages：

High Load-bearing Capacity：The double-row roller design endows it with excellent radial load-bearing capacity, which can effectively support the operation of heavy-duty equipment and extend the service life of the equipment.
Adaptability to Various Working Conditions：According to different usage requirements, choosing nylon or brass cages can adapt to different working environments, such as high-speed and light-load or low-speed and heavy-load working conditions.
Low Friction and Long Service Life：The self-lubricating property of the nylon cage and the high strength of the brass cage both help to reduce the internal friction of the bearings, reduce wear, improve the service life of the bearings, and lower maintenance costs.

Application

The bearings can be used in the following industries

Heavy-duty Machine Tools：It can be used in the spindle systems of heavy-duty lathes, milling machines and other machine tools, bearing the huge radial forces during the machining process and ensuring the machining accuracy.
Metallurgical Equipment：In metallurgical machinery such as rolling mills and forging equipment, this series of bearings can reliably support heavy-duty components and adapt to harsh working environments such as high temperature and high dust.
Mining Machinery：Suitable for mining equipment such as crushers and ball mills, it provides reliable support for the stable operation of the equipment and reduces the downtime of equipment failures.
