When you need to replace a tapered roller bearing, the full designation matters. The NSK HR J series covers a wide range of sizes, each identified by its own part number, such as HR 30203 J, HR 32222 J, or HR 33120 J. These bearings share a common design, but their dimensions differ from one number to the next. That is why the complete part number is essential for a correct replacement.

A single-row tapered roller bearing consists of cone-shaped rollers running between two angled raceways. This configuration handles combined radial and axial loads, but only in one axial direction. The inner ring, rollers, and cage form the cone, which is separable from the outer ring, or cup. This separability simplifies mounting and allows for individual component replacement.

Since axial capacity is limited to one direction, these bearings are typically installed in opposed pairs. This arrangement enables the assembly to accommodate axial loads from both sides. During installation, clearance or preload must be set according to the manufacturer's specifications. Proper adjustment is critical because it directly affects bearing life and performance.

The part number comprises three elements: the HR prefix, a five-digit numeric code, and the J suffix. Both the prefix and suffix are integral to the complete designation and should never be left out. The numeric portion indicates the series and size, which is why this product family includes bearings with vastly different dimensions. Always refer to the full part number for exact dimensions.

Common applications include wheel hubs, gearboxes, transmissions, and shafts in heavy machinery—essentially any setup with combined loads. For replacement, locate the part number etched on the bearing ring and provide it in full. If the marking is unreadable, measure the bore, outer diameter, and width to identify the correct bearing.
