Eliminate Downtime with Genuine NSK NU311 Cylindrical Roller Bearings

Auto spare parts manufacturers and repair shops know the cost of bearing failure: unscheduled downtime, production delays, and expensive replacements. When low-quality bearings fail prematurely in critical components like transmissions or axles, the ripple effect disrupts entire operations. Sourcing reliable, high-precision bearings with flexible ordering and fast delivery has long been a challenge in the industry.

Genuine NSK NU311 Bearings: Precision You Can Rely On

The NSK NU311 Cylindrical Roller Bearing solves these pain points with its authentic Japanese manufacturing and strict quality control. As an integrated bearing supplier with ISO9001 certification, we ensure every NSK NU311 bearing meets P0-P4 precision standards, delivering consistent performance in automotive and industrial applications. With 1pc MOQ for standard items and 3-5 days sample lead time, we support both small-batch repairs and large-scale production needs.

Engineered for High-Radial Load Applications

This cylindrical roller bearing excels in environments with heavy radial loads and moderate speeds, making it ideal for automotive transmissions, machine tool spindles, and industrial gearboxes. Its separated inner and outer rings allow for easy mounting and dismounting, simplifying maintenance procedures. The open design facilitates lubrication customization, ensuring optimal performance in diverse operating conditions—from high-temperature industrial settings to the demanding environments of agricultural machinery.

Precision Parameters That Matter

The NU311’s technical specifications directly impact equipment performance. With a bore diameter of 55mm, outer diameter of 120mm, and width of 29mm, it fits standard automotive and industrial component dimensions. The P0-P4 precision ratings ensure minimal vibration and noise, critical for passenger vehicle comfort and industrial equipment accuracy. As a radial bearing, it efficiently handles axial displacement, protecting adjacent components from excessive stress during operation. The bearing steel construction provides the durability needed to withstand continuous use in high-load applications.

Why Authenticity Beats Counterfeit Savings

Choosing genuine NSK NU311 bearings over counterfeit alternatives reduces total cost of ownership significantly. Counterfeit bearings often fail within months, leading to repeated replacements, production downtime, and potential damage to expensive equipment. In contrast, our authentic NSK bearings come with a 12-month global warranty, ensuring reliability and long service life. Each unit is traceable to the original manufacturing process, giving you confidence in the quality and performance of every bearing you install.
