SKF NU 228 ECJ is a single row cylindrical roller bearing of NU design with a pressed steel cage. The outer ring has two integral flanges; the inner ring has none, so the shaft can move axially in both directions. The inner ring is separable. It is the floating bearing in gearboxes, motors, pumps and rolling mill equipment.
NU — two flanges on the outer ring, no flanges on the inner ring. Non-locating bearing.
2 — dimension series 02, light section.
28 — bore code, 28 x 5 = 140 mm bore.
EC — SKF optimized internal design with increased load capacity.
J — pressed steel cage.
