The INA HK series needle roller bearing is a radial needle roller bearing with a drawn cup outer ring and no inner ring. It is used when the shaft acts directly as the raceway and radial space is limited. Its compact design allows it to be mounted in machined housings with an interference fit, and it is common in applications that require high load capacity in a small volume. MR Accesorios Industriales sells this line, with technical advice to select the correct part number.

The HK series designation is read by numbers: the first two indicate the shaft diameter in millimeters and the next two the width of the drawn cup. For example, HK0408 fits a 4 mm shaft with 8 mm width; HK0810 corresponds to an 8 mm shaft and 10 mm width. This logic makes it quick to identify the size you need without a table.

In Argentine industry, INA HK series needle roller bearings are used in transmissions, pumps, compressors, machine tools and packaging equipment. They also appear in conveyor rollers, joints and lifting mechanisms. Because they have no inner ring, the shaft must have suitable hardness and be ground to function as a raceway. They are common in repairs where space is critical and bushings are being replaced with needle roller bearings.

To select the drawn cup, check the shaft diameter and tolerance, the available width and the type of load. Mounting is done by pressing it into the housing, with tooling that does not deform the drawn cup. Lubrication can be grease or oil depending on the environment; in contaminated applications, consider external seals or versions with a seal. Alignment between shaft and housing is key to avoid edge loads. If the shaft is not hardened, it is advisable to use a version with an inner ring.

Needle roller bearings are interchanged between manufacturers by dimensional part number: the same shaft diameter and width usually has equivalents in other brands. However, check tolerances, load capacity and type of drawn cup before replacing. INA is a reference in this family, and MR Accesorios Industriales sells the line. For equivalents, the safest approach is to compare the complete designation and consult with the supplier.
