NU-30 Series

The NU30 series cylindrical roller bearings are single-row, separable precision bearings designed for heavy radial load applications, with our core advantage being full coverage of precision grades including P2, UP, P4, SP, P5 and P6. Featuring a removable inner ring, they are easy to install and maintain, while the integrated K (tapered bore) and W33 (lubrication groove and oil hole) designs enhance adaptability and operational reliability. Constructed from high-carbon chromium steel, these bearings deliver exceptional rigidity, low noise, and high-speed stability, making them suitable for both general industrial and high-precision scenarios.

 
NU-30 Bearing Applications

 NU30 series bearings are widely used in key rotating equipment across industries. They are the preferred choice for gearboxes, reducers, and electric motors requiring heavy radial load capacity, and also excel in CNC machine tool spindles, textile machinery, and printing presses with P4/SP/P5 precision demands. For industrial conveyor systems, mining machinery, and paper mills, the P6 grade offers cost-effective durability, while the P2/UP ultra-precision grades support high-end applications such as aerospace components and semiconductor manufacturing equipment. The K taper bore and W33 lubrication system further make them ideal for large fans, compressors, and metallurgical rolling mills that demand reliable lubrication and shaft fit flexibility
