The NSK FJLTT series is a line of radial needle roller bearings built to carry high radial loads in a very slim cross-section. They fit where radial space is tight and load capacity still matters, such as gearboxes, pumps, compressors and machine tools.
The FJLTT code starts with the letters FJLTT and ends with four digits that define the main dimensions. Examples in the series include FJLTT-1014, FJLTT-1216, FJLTT-1422, FJLTT-1516, FJLTT-1521, FJLTT-1626 and FJLTT-1721. As a rule, the first two digits point to the bore diameter and the last two to the outside diameter, but this can change from size to size, so always confirm with the full part number.
These bearings appear in automotive, metallurgy, food processing and machine tool applications. They are common in transmissions, hydraulic pumps, air compressors and linear motion equipment. The thin profile and radial load capacity make them a practical choice when a conventional bearing will not fit the available space.
When specifying a bearing, check three dimensions: shaft diameter, housing diameter and seat width. The FJLTT series has no integral seal, so add a radial shaft seal or other external sealing if dust or moisture is present. Grease or oil can be used for lubrication, depending on speed and operating temperature. Correct alignment between shaft and housing helps prevent unwanted axial loads and supports service life.
NSK needle roller bearings can be interchanged with other brands that use the same standard dimensions. If you have a part number from another maker, we can help you find the equivalent. On replacement, verify that shaft and housing tolerances match the manufacturer's recommendations.
