NSK HR30226J Tapered Roller Bearing

Description

The NSK HR30226J is a high-performance, single-row tapered roller bearing engineered to accommodate combined radial and axial loads. Its robust construction makes it ideal for use in gearboxes, hoisting equipment, rolling mills, and other heavy industrial machinery. The separable design, with a separate cone (inner ring with roller and cage assembly) and cup (outer ring), simplifies installation, removal, and maintenance procedures.

FAQ

The 'HR' prefix designates NSK's High-Capacity series of tapered roller bearings. These bearings are designed with an optimized internal geometry and a greater number or size of rollers to provide a significantly higher load rating compared to standard series bearings of the same dimensions.

Standard NSK bearings with a steel cage, like the HR30226J, are typically stable for continuous operation at temperatures up to 120 deg C (250 deg F). For applications with higher operating temperatures, special materials, heat treatment, and lubricants may be required. Please consult the manufacturer's guidelines for specific temperature limits.

While the boundary dimensions (bore, OD, width) of 30226 bearings are standardized by ISO, internal geometry and roller profiles can vary between manufacturers. For optimal performance, longevity, and load distribution, it is strongly recommended to use the cone and cup from the same manufacturer and production batch. Mixing components is not advised.
