SKF NN 3026 KM/SPW33 double-row super-precision cylindrical roller bearing. Bore: 130 mm, tapered 1:12. Outside diameter: 200 mm. Width: 52 mm. Series: NN 30. Two rows of cylindrical rollers, machined brass cage, open, with a W33 lubrication groove and three feed holes in the outer ring.
NN: double-row cylindrical roller, ribs on the inner ring, plain separable outer ring. 3026: series NN 30, bore code 26, 130 mm bore. K: 1:12 tapered bore. M: machined brass cage. SP: super-precision tolerance class, P5 running accuracy. W33: lubrication groove plus three radial feed holes in the outer ring.
A double-row cylindrical roller bearing carries high radial load in a short axial space and gives a machine-tool spindle its radial stiffness. The 1:12 tapered bore sets radial clearance by how far the inner ring is driven up the taper, so clearance is adjustable at assembly. Internal Clearance: C1, a reduced clearance for close spindle location. Limiting speed: 5,300 rpm. Operating temperature range: -30 to +150 °C.
One bearing, 1 Pc. Inner ring, roller and cage assemblies, and separable outer ring.
The 1:12 tapered bore mounts directly on a tapered spindle journal. Drive-up on the taper sets the running clearance, and the W33 groove aligns with the oil or grease feed in the housing. Rollers are guided by the ribs on the inner ring, so the outer ring lifts off as a plain sleeve.
FAG NN3026-AS-K-M-SP, NSK NN3026MBKRE4, Timken NN3026K and Koyo NN3026K are the same 130 x 200 x 52 mm double-row tapered-bore size in the same class. SKF NN 3026 KTN9/SPW33 is a related execution on the same envelope with a glass-fibre polyamide cage and its own load ratings. Searchable forms: NN3026KMSPW33, NN 3026 KM/SPW33, NN-3026-K-M-SP-W33, NN3026.
