The INA NKIA-XL series needle roller bearing is a combined unit that integrates a radial needle roller bearing and an axial self-aligning bearing in a single assembly. It is used where space is limited and simultaneous radial and axial loads must be absorbed, for example in pulleys, gears and machine shafts. MR Accesorios Industriales sells this INA line in Buenos Aires, Argentina, and advises you on choosing the correct part number.

The NKIA-XL designation is read as follows: NKIA identifies the combined unit of radial needle rollers with axial self-aligning bearing, and XL is the suffix of the current manufacturing generation. The number that follows the letters indicates the size: in NKIA59/22-XL the 59/22 corresponds to a compact size of the 59 series, while in NKIA5901-XL, NKIA5902-XL and NKIA5903-XL the last digit orders the sizes within the same family. Part numbers such as NKIA5904-XL, NKIA5905-XL, NKIA5906-XL and NKIA5907-XL follow the same logic: same concept, different dimensions. Send me the complete part number and we will quote it.

These bearings appear in applications where axial and radial space is critical: idler pulleys, rollers of textile machines, packaging equipment, compact transmissions and lifting mechanisms. In the Argentine market they are seen in machine tool maintenance, food production lines and material handling equipment. By combining radial and axial load in a single component, they simplify the support design and reduce the number of parts to be mounted.

To select the correct part number, take into account the radial and axial load it will carry, the shaft diameter and the housing dimensions. Mounting requires cleanliness, careful alignment and adequate lubrication: the radial needle rollers and the axial self-aligning bearing may require different lubricant depending on speed and temperature. Verify the clearance and sealing of the assembly; if the environment is dusty or humid, consider additional protection. If in doubt, consult us with the part number and the mounting drawing.

As for equivalents, the INA NKIA-XL series can be interchanged with combined bearings from other manufacturers that share dimensions and load capacity, but you should not go by diameter alone: verify tolerances, type of axial self-aligning bearing and lubrication conditions. MR Accesorios Industriales sells INA and can guide you on alternatives within the same family. It is always advisable to confirm interchangeability with the original part number and the dimensions measured on the equipment.
