SKF NN 3017 K super-precision double-row cylindrical roller bearing with a tapered bore. Bore Diameter: 85 mm. Outside Diameter: 130 mm. Overall Width: 34 mm. Number Of Rows: 2. Rolling Elements: Cylindrical Roller. Bore Type: Tapered 1:12. Cage Material: Machined brass. Precision Class: P5. Closure Type: Open. Bearing Material: Bearing steel. Series: NN 30. Base Number: NN 3017.
NN is the double-row cylindrical roller design with ribs on both rings. 3017 is the 30 dimension series at an 85 mm bore. K is a 1:12 tapered bore. M is a machined brass cage. P5 is the precision class. Written as NN-3017-KMC/C481, NN-3017-K-M-P5, NN3017 and NN 3017 K.
Two rows of short cylindrical rollers in a narrow section give very high radial capacity and very high radial stiffness in a small envelope, which is why this is the standard front-bearing choice for a machine tool spindle. P5 holds bore, outside diameter and running accuracy to tighter limits than standard tolerance, so the spindle nose runs true. On a double-row cylindrical roller the static rating sits above the dynamic rating; that is the normal relationship for this type, not a transposition.
Unit Quantity: 1 Pc. One bearing per sale unit, open on both faces.
The 1:12 tapered bore seats directly on a matching tapered spindle journal, and driving the inner ring up that taper is what sets the radial clearance — the preset is made at assembly rather than being built into the bearing. Shaft abutment diameter: 91.5 mm minimum. Housing abutment diameter: 119 mm minimum to 123.5 mm maximum. Shaft and housing fillet radius: 1 mm maximum. Bearing chamfers r1,2: 1.1 mm minimum and r3,4: 0.6 mm minimum. Inner ring shoulder diameter: 102 mm. Outer ring raceway diameter: 118 mm. Oil nozzle position: 116.4 mm. Permissible axial displacement of one ring relative to the other: 2 mm maximum.
NN 3017 K is an ISO-pattern designation and the tapered-bore and brass-cage codes translate across the spindle-bearing makers. Cross-Reference 1: FAG NN3017-AS-K-M-SP. Cross-Reference 2: NSK NN3017TBKRE44CC1P4. Cross-Reference 3: NTN NN3017KC1NAP4. Cross-Reference 4: SKF NN 3017 KTN9/SP (related, glass-fibre polyamide cage execution). Searchable forms: NN-3017-KMC/C481, NN-3017-K-M-P5, NN3017KM, NN3017, NN 3017 K.
