The NTN BK series needle roller bearing is a compact single-row radial bearing with a machined outer ring and open ends. It is used when radial space is limited and radial loads must be supported with high capacity relative to its size. It is common in transmissions, power tools, pumps and automation equipment. MR Accesorios Industriales sells this NTN line in Buenos Aires, Argentina, and helps you identify the right size for your application.

The BK series designation is read in blocks: the number following the abbreviation indicates the bore diameter and the width. For example, in 7E-BK4012CT, the prefix 7E identifies an execution variant, BK is the needle roller bearing series with outer ring, 40 corresponds to the bore diameter and 12 to the width. The suffix CT defines the cage type and sealing. With that data you can locate the exact reference within the BK family.

This type of bearing is used in Argentine industries such as food, metalworking, textile and automotive. It appears in transmission cases, pumps, compressors, machine tools, packaging equipment and portable power tools. Its low profile allows it to be mounted in spaces where a deep groove ball bearing does not fit. It is also used in continuous rotation applications with moderate radial loads and medium speeds.

To select the correct bearing, take into account the shaft diameter, the available width and the type of load. The BK series handles radial loads; if there is axial load, it is best to combine it with another bearing. Assembly requires alignment between shaft and housing, and adequate lubrication according to speed and working temperature. The sealing of the CT suffix protects against contaminants and retains lubricant, which extends service life in environments with dust or moisture.

If you need to replace a bearing from another brand, interchangeability is defined by the main dimensions: bore diameter, outer diameter and width. With those three data points you can search for the equivalent in the NTN BK series. The competitor's code alone is not enough: tolerances and cage type must be verified.
