NSK NN3022MBKRCC1P4 is a double row cylindrical roller bearing of the NN3022K type, built to super-precision tolerances with a tapered bore and a machined brass cage. Bore Diameter: 110 mm. Outside Diameter: 170 mm. Overall Width: 45 mm. Rolling Elements: Cylindrical Roller. Number Of Rows: 2. Closure Type: Open. Bearing Material: Bearing steel. Series: NN30 double row cylindrical roller. Base Number: NN3022.
NN — double row cylindrical roller bearing.
3022 — 30 dimension series, 110 mm bore.
MB — machined brass cage.
K — 1:12 tapered bore.
P4 — ISO class 4 precision, ABEC 7 equivalent.
Dynamic Load Rating: 281,000 N. Static Load Rating: 375,000 N. Limiting Speed: 3,400 rpm grease; 4,300 rpm oil. Precision Class: ABEC 7 / P4. Cage Material: Brass. Cage Type: Machined. Item Weight: 3.71 kg (8.18 lb). The two roller rows carry radial load only; axial location comes from a separate thrust member in the spindle.
Bore Type: Tapered 1:12. Shaft abutment diameter da min: 119 mm. Housing abutment diameter Da: 157–161 mm. Chamfer r min: 2 mm. Fillet radius ra max: 2 mm. Lubricant: Grease or oil. The tapered bore seats directly on a matching 1:12 taper on the spindle journal; no adapter sleeve is used. Driving the inner ring up the taper expands it and sets the running clearance.
Unit Quantity: 1 Pc. Mounting Arrangement: Single bearing, radial location on a tapered journal.
FAG NN3022-AS-K-M-SP is the super-precision, machined brass cage, tapered bore match on the 110 · 170 · 45 mm size. SKF NN 3022 K, Koyo NN3022K, NTN NN3022K and NSK NN3022K share the size, the two roller rows and the 1:12 tapered bore but are standard class, not P4. The NN3022 with a cylindrical bore is a different bore form.
