When radial space is tight but loads are heavy, the NSK B series needle roller bearing is a common choice. Its thin cross-section fits into gearboxes, pumps, compressors and machine tools where rigidity matters. MR Industrial Accessories supplies this line to customers across the United States and Latin America, and can help you pin down the exact size.

The code itself tells you the size. A letter B comes first, then a number that sets the bore and width. So B-24, B-34 and B-44 are three different sizes. When the code includes a fraction, like B-2 1/2 4 or B-2 1/2 5, the mixed number gives the bore in inches and the final digit gives the width. Reading the code correctly saves you from measuring the old part.

You will find these bearings in automotive, metalworking, food processing and mining equipment. They show up in transmissions, water pumps, air compressors, industrial sewing machines and material handling gear. The ability to carry high radial loads in a small envelope makes them suitable for tough environments.

Selection depends on shaft diameter, radial load and lubrication. The B series is typically mounted with an interference fit on the shaft and a clearance fit in the housing. Check alignment and use the right lubricant, because the needles are sensitive to contamination. If dust or moisture is present, add seals.

NSK B series bearings can be interchanged with other brands that use the same dimensional nomenclature. If you have a code from another maker or an unidentified part, send us the measurements or the code and we will point you to a compatible equivalent. MR Industrial Accessories helps you find the part you need.
