ZKL NN3012 W33 P51 NA is a double-row cylindrical roller bearing with a cylindrical bore, built to P5 precision with C1 radial clearance for machine tool spindles. The NN design carries the guide ribs on the inner ring and a plain outer ring.
NN — double-row cylindrical roller bearing, ribs on the inner ring.
30 — ISO dimension series 30.
12 — bore code, 12 x 5 = 60 mm bore.
W33 — lubrication groove and three radial holes in the outer ring, for grease or oil feed.
P51 — P5 dimensional and running accuracy combined with C1 radial clearance.
NA — radial clearance set for non-interchangeable rings; the inner and outer rings are a matched pair.
