FAG NN3017KM.SP (NN3017-K-M-SP) is a super-precision double-row cylindrical roller bearing for machine tool main spindles. Bearing type: Double-row cylindrical roller bearing. Bore Diameter: 85 mm. Outside Diameter: 130 mm. Overall Width: 34 mm. Number Of Rows: 2.
NN30 — double-row cylindrical roller bearing, ISO dimension series 30. Three ribs on the inner ring, plain separable outer ring; non-locating bearing.
17 — bore code, 17 x 5 = 85 mm.
K — tapered bore, taper 1:12. Mounts directly on a tapered spindle journal; radial internal clearance is set by axial drive-up.
M — machined brass cage, roller guided.
SP — Schaeffler super-precision tolerance class SP.
Bore Type: Tapered 1:12. Cage Material: Machined brass. Precision Class: SP (super precision). Seal type: Open. Closure Type: Open. Lubricant: grease or oil. The double row of rollers gives high radial rigidity and load capacity in a thin 30-series section, the standard arrangement at the work end of lathe and machining-centre spindles.
Successor NN3017-D-K-TVP-SP-XL data (Schaeffler medias): Dynamic load rating 138,000 N. Static load rating 183,000 N. Fatigue load limit 27,500 N. Limiting speed 8,200 rpm grease; 9,700 rpm oil. Mass 1.457 kg. Axial displacement 2.5 mm. Outer ring raceway diameter 118 mm. Operating temperature −30 °C to +120 °C. The successor carries a polyamide TVP cage in place of the brass M cage on the same 85 x 130 x 34 mm envelope.
Successor NN3017-D-K-TVP-SP-XL data: shaft shoulder diameter 98 mm (h12), housing shoulder diameter 120.6 mm (H12), maximum recess radius 1 mm, minimum chamfer 1.1 mm, lubrication injection pitch diameter min 116.3 mm.
Compatible With / Replaces: FAG NN3017-D-K-TVP-SP-XL is the current Schaeffler execution on this envelope. Cross-Reference: SKF NN 3017 K/SP. MPN Variants: NN3017KM.SP, NN3017-K-M-SP, NN3017KMSP, NN 3017 K M SP, NN 3017 AS K M SP.
