FAQ

What does the 'HR' prefix in HR30315J signify?

The 'HR' prefix on an NSK tapered roller bearing stands for 'High-Reliability'. These bearings are manufactured with high-quality case-carburized steel and have an optimized internal design for increased load capacity and longer service life compared to standard series bearings.

Yes, the HR30315J is designed for universal matching. It can be mounted in pairs, such as back-to-back (DB), face-to-face (DF), or tandem (DT) arrangements, to accommodate higher loads or provide specific levels of stiffness. Ensure proper preload and mounting procedures are followed for paired applications.

The appropriate lubrication depends on the operating speed, load, and temperature of the application. Both grease and oil lubrication are suitable. For most general industrial applications with moderate speeds, a high-quality lithium-based grease (NLGI grade 2) is sufficient. For high-speed or high-temperature applications, oil lubrication (e.g., circulating oil or oil bath) is recommended. Always consult your machinery's manual for specific lubrication requirements.
