SKF NN 3008 AKMC/C481 is a double row cylindrical roller bearing from the SKF NN 30 super-precision series, for machine tool spindles and other assemblies that need high radial stiffness at speed. Bore Diameter: 40 mm. Outside Diameter: 68 mm. Overall Width: 21 mm. Number Of Rows: 2. Rolling Elements: Cylindrical Roller. Bore Type: Tapered 1:12. Cage Material: Machined brass. Cage Type: Machined. Closure Type: Open. Bearing Material: Bearing steel. Unit Quantity: 2 Pcs.
NN — double row cylindrical roller bearing. Two rows of rollers run on one inner ring and carry radial load.
3008 — NN 30 dimension series with bore code 08, the 40 x 68 x 21 mm envelope.
K — tapered bore, taper 1:12.
M — machined brass cage.
Inner Ring Flanges: 3. Outer Ring Flanges: 0. Separable: Yes. Dynamic Load Rating: 42,900 N. Static Load Rating: 56,000 N. Lubricant: Grease or oil. Snap Ring Included: No. Series: NN 30. Base Number: NN 3008. Harmonization Code: 8482.50.00.00. The flangeless outer ring separates from the inner ring and roller assembly.
Bore Diameter: 40 mm, at the small end of the 1:12 taper. Outside Diameter: 68 mm. Overall Width: 21 mm. Mounts directly on a tapered journal. Each piece is a complete bearing: inner ring with rollers and cage, plus its outer ring.
NN 30 boundary dimensions are standardised across makers. FAG NN3008-AS-K-M-SP, NSK NN3008K, NTN NN3008K, Koyo NN3008K and NACHI NN3008K carry the same 40 x 68 x 21 mm envelope. SKF NN 3008 KTN9/SP is the current-production execution at this size, with a polyamide cage.
40 mm bore, 68 mm outside diameter, 21 mm width.
