The NTN BK series is a single-row needle roller bearing with a machined outer ring and open ends. It fits where radial space is tight and radial load capacity must be high for the bearing size. Typical equipment includes transmissions, power tools, pumps and automation systems. MR Industrial Accessories supplies this line to customers across the United States and in several Latin American countries, and can help you match the right size to your application.

Reading the code helps you find the exact reference. In 7E-BK4012CT, the 7E prefix marks an execution variant, BK is the needle roller bearing series with outer ring, 40 is the bore diameter and 12 is the width. The CT suffix sets the cage type and sealing. Once you have those elements, you can locate the correct item in the BK family.

This bearing type appears in transmission cases, pumps, compressors, machine tools, packaging equipment and portable power tools. Its low profile lets it be mounted where a deep groove ball bearing will not fit. It also suits continuous rotation with moderate radial loads and medium speeds.

For selection, check shaft diameter, available width and load type. The BK series carries radial loads; if axial load is present, combine it with another bearing. Assembly calls for alignment between shaft and housing, plus suitable lubrication for the speed and working temperature. The sealing of the CT suffix keeps contaminants out and lubricant in, which supports service life in dusty or damp environments.

When replacing a bearing from another brand, interchangeability comes down to bore diameter, outer diameter and width. Those three dimensions let you search the NTN BK series for an equivalent. The other brand's code alone is not enough: tolerances and cage type also need checking. Send us the original part code and we will identify the compatible alternative.
