The INA BK series needle roller bushing is a compact radial bearing of the bushing type, with cage and needles, that is mounted directly on the shaft and inside a housing. It is used when radial space is limited and high load capacity is needed with a reduced outside diameter. MR Accesorios Industriales supplies this INA line in Buenos Aires, Argentina, with technical advice to select the correct code according to the application.

The designation of the BK series is read as a size code: the first two figures after the letters indicate the shaft diameter in millimeters, and the next two, the width of the bushing. For example, BK0408 corresponds to a 4 mm shaft and a width of 8 mm; BK0912, to a 9 mm shaft and a width of 12 mm. In the examples BK0509, BK0609, BK0709, BK0808, BK0810 and BK0910 the same logic is repeated. This nomenclature allows quick identification of the size without the need to consult additional tables.

INA BK series needle roller bushings are used in a wide variety of industrial applications in Argentina: transmissions, pumps, compressors, machine tools, packaging equipment and linear motion systems. Their compact design makes them suitable for spaces where a conventional ball bearing does not fit. They are also used in the automotive sector, in components such as gearboxes and steering systems, and in agricultural machinery, where resistance to radial loads and the ability to withstand moderate speeds are decisive.

To correctly select a BK bushing, take into account the shaft diameter and tolerance, the housing diameter and tolerance, and the available width. The BK series accepts grease or oil lubrication; in applications with contamination, evaluate additional sealing. Mounting is done by pressure, with suitable tooling so as not to damage the needles or the cage. It is essential to verify the alignment between shaft and housing, since excessive misalignment reduces service life.

Regarding equivalents, needle roller bushings are manufactured under dimensional standards that allow products to be interchanged between different brands when the dimensions and the type of execution match. INA is a reference in this family, and on the market there are alternatives from other manufacturers with standardized dimensions. To replace an existing bushing, the safest approach is to compare the complete code and the mounting tolerances. If you have doubts, send us the original code and we will help you find the right option.
