NU and NJ designs with separable rings
Line contact between roller and raceway gives this type far more radial capacity than a ball bearing of the same size, which is why it lands in gearbox output shafts, motor drive ends, and mill positions. Inventory includes single-row NJ and NU designs in metric sizes such as 45x85x23 mm and 90x160x34 mm, Link-Belt numbers, and a few non-standard widths with no direct ISO interchange. Because the rings separate, note which ring your housing or shaft actually needs; an NU where the position calls for an NJ rib leaves the shaft without axial location. Send bore, OD, width, and any design letters and we will confirm the fit. Tight radial space instead? Try needle roller bearings.
