The INA NK-XL series is a single-row radial needle roller bearing built around a machined outer ring, supplied without an inner ring. It is intended for arrangements where radial space is limited and the shaft itself serves as the raceway, which keeps the surrounding design simple and light. MR Industrial Accessories supplies this series and helps customers match the right part number to the application.

Reading the designation: NK tells you this is a needle roller bearing with a machined outer ring and no inner ring. The number right after the letters is the bore diameter, and the number following the slash is the overall width. The -XL suffix marks the manufacturer's current design, which carries dimensional and load capacity refinements. So NK16/20-XL is a bearing with a 16 mm bore and a 20 mm width.

Typical installations include machine tools, pumps, compressors, gearboxes, conveyors, packaging lines and agricultural equipment. Because the bearing handles considerable radial load while keeping a low profile, it fits gearboxes, shaft supports and mechanisms where radial room is scarce. It also suits arrangements that call for high rigidity and rotational precision, such as grinding spindles and milling heads.

When selecting an NK-XL bearing, look at the radial load, the rotational speed, the lubrication available and the sealing the location needs. With no inner ring, the raceway has to be machined on the shaft with the right hardness and surface finish; if the shaft cannot meet that, pair the bearing with a suitable inner sleeve. At mounting, check alignment between shaft and housing and confirm radial clearance for the application. Grease or oil both work as lubricants, and in dirty environments add separate seals.

For interchangeability, needle roller bearings without an inner ring from other manufacturers can stand in for the NK-XL series provided the bore, outer diameter and width, along with the load capacities, line up. Tolerances and the design type, open or sealed, also need checking so operation stays equivalent. On critical applications, run the replacement past our technical team before committing to it.
