NSK NN3008MBKRCC1P4 is a double-row cylindrical roller bearing in the ISO NN3008 size: 40 mm bore, 68 mm outside diameter, 21 mm width. Two rows of cylindrical rollers, machined brass cage, 1:12 tapered bore, P4 precision (ABEC 7), open design. Unit Quantity: 1 Pc: one complete bearing with inner ring, outer ring, both roller rows and cage.
NN — double-row cylindrical roller bearing; the guiding ribs are on the inner ring.
30 — dimension series 30.
08 — bore code, 08 x 5 = 40 mm.
MB — machined solid brass cage.
K — 1:12 tapered bore.
P4 — ISO P4 precision class, equivalent to ABEC 7.
Bore Diameter: 40 mm (1.5748 in). Outside Diameter: 68 mm (2.6772 in). Overall Width: 21 mm (0.8268 in). Number Of Rows: 2. Rolling Elements: Cylindrical Roller. Cage Material: Machined brass. Bore Type: Tapered 1:12. Precision Class: ABEC 7 / ISO P4. Closure Type: Open. Series: NN30. Unit Quantity: 1 Pc.
