NJ309 Cylindrical Roller Bearing
NJ309 is a single row cylindrical roller bearing with a 45 mm bore, 100 mm outer diameter and 25 mm width, built to the ISO 15 boundary dimensions of the NJ3000 series. It is the largest size in the series. It carries high radial load and provides no axial location, so the shaft position must be fixed by another bearing in the arrangement.
Because the boundary dimensions are fixed by ISO 15, the NJ309 is interchangeable with SKF NJ309, NSK NJ309, FAG NJ309 and NTN NJ309: it fits the same 45 mm shaft and the same housing bore. Cage material, internal clearance, precision grade and sealing differ between makers and should be confirmed against the application before substitution.
