NTN NN3022KC1NAP4 precision double row cylindrical roller bearing with tapered bore, type NN. Bore Diameter: 110 mm. Outside Diameter: 170 mm. Width: 45 mm. Bore Type: Tapered 1:12. Precision Class: RBEC 7 / P4. Internal Clearance: C1NA.
NN — double row cylindrical roller bearing, ribs on the inner ring, plain separable outer ring.
30 — ISO dimension series 30.
22 — bore code, 110 mm.
K — 1:12 tapered bore; mounts directly on a tapered spindle journal.
C1NA — C1 radial clearance, non-interchangeable: inner and outer ring are matched and supplied as a set.
P4 — ISO Class 4 precision.
Dynamic Load Rating: 229,000 N. Static Load Rating: 375,000 N. Limiting Speed: 3,600 rpm grease; 4,300 rpm oil. Item Weight: 3.51 kg (7.74 lb). Cage Material: Machined brass. Operating Temperature: -40 °C to 120 °C. Two rows of rollers give very high radial stiffness; the tapered bore lets radial clearance be set to zero or a slight preload by axial drive-up, the standard arrangement for lathe and machining-centre spindle noses.
Roller outside envelope Ew: 155 mm. Shaft abutment da min: 119 mm. Housing abutment Da max: 157 mm. Fillet r: 2.0 mm; ras max: 2.0 mm.
Matching tapered-bore P4 designs: NSK NN3022MBKRCC1P4 (brass cage), FAG NN3022-AS-K-M-SP (brass cage, outer-ring lube groove), SKF NN 3022 KTN9/SP (polyamide cage) and Koyo NN3022K (normal class, not P4).
