Product description of NSK Bearing HR32052XJ
NSK Bearing HR32052XJ Category: NSK Bearing > Rolling Bearings > Tapered Roller Bearings > Single-Row Metric Design. For metric-design medium-angle and steep-angle tapered roller bearings, the respective contact angle symbol C or D is added after the bore number. For normal-angle tapered roller bearings, no contact angle symbol is used. Medium-angle tapered roller bearings are primarily used for the pinion shafts of differential gears of automobiles. Among those with high load capacity (HR series), some bearings have the basic number suffixed by J to conform to the specifications of ISO for the cup back face raceway diameter, cup width, and contact angle. Therefore, the cone assembly and cup of bearings with the same basic number suffixed by J are internationally interchangeable. Among metric-design tapered roller bearings specified by ISO 355, there are those having new dimensions that are different than the dimension series 3XX used in the past. Part of them are listed in the bearing tables. They conform to the specifications of ISO for the smaller end diameter of the cup and contact angle. The cone and cup assemblies are internationally interchangeable. The bearing number formulation, which is different than that for past metric design, is as follows:
NSK Bearing HR32052XJ Bearings of this type use conical rollers guided by a back-face rib on the cone. These bearings are capable of taking high radial loads and axial loads in one direction.
In the HR series, the rollers are increased in both size and number giving it an even higher load capacity. They are generally mounted in pairs in a manner similar to single-row angular contact ball bearings. In this case, the proper internal clearance can be obtained by adjusting the axial distance between the cones or cups of the two opposed bearings. Since they are separable, the cone assemblies and cups can be mounted independently.
Depending upon the contact angle, tapered roller bearings are divided into three types; normal angle, medium angle, and steep angle.
Double-row and four-row tapered roller bearings are also available. Pressed steel cages are generally used.
NSK Bearing HR32052XJ Tapered roller bearings can carry radial loads and unidirectional axial loads and offer high capacity.These bearings are used widely in machines with relatively severe loading conditions, usually in various combinations of opposed or combined single-row bearings.
NSK Bearing HR32052XJ Tapered roller bearings are usually lubricated with grease to facilitate easier maintenance and inspection. Be sure to select a grease appropriate for operating conditions and use the proper amount of grease in the housing space. The necessary free space for various bearing Series are listed in Table 6.The free space of a tapered roller bearing is measured as the outer volume of the bearing the inner ring, outer ring, and cage, as shown in Figure 1. The bearing is filed SO that grease reaches the inner ring rib surface and pocket surface sufficiently. Take care regarding the fill amount and state of the grease, especially if grease leakage occurs or if maintaining low running torque is important.
