A single-row cylindrical roller bearing on a tapered bore, in NSK’s N10 super-precision machine tool series. Bore Diameter: 70 mm. Outside Diameter: 110 mm. Overall Width: 20 mm. Rolling Elements: Cylindrical Roller. Number Of Rows: 1. Bore Type: Tapered 1:12. Closure Type: Open. Precision Class: ABEC 7 / P4. Bearing Material: Bearing steel.
N — cylindrical roller bearing, N type. Two integral ribs on the inner ring, a plain ribless outer ring. The rollers and inner ring can move axially relative to the outer ring, so the bearing floats and carries radial load only.
1014 — the N10 light section at 70 mm bore, 110 mm outside diameter, 20 mm width.
K — 1:12 tapered bore. Bore Type: Tapered 1:12.
P4 — ISO tolerance class 4. Precision Class: ABEC 7 / P4.
A 20 mm width on a 70 mm bore puts this in the thin light section used for machine tool spindles, where radial stiffness and running accuracy matter more than load capacity.
ABEC 7 / P4 tightens bore, outside diameter, width and running-accuracy tolerances well beyond Normal class. That is the class range in which spindle runout is held to single-digit microns.
Bore Diameter: 2.7559 in. Outside Diameter: 4.3307 in. Overall Width: 0.7874 in. The 1:12 tapered bore seats directly on a matching tapered spindle journal. Driving the inner ring further up the taper expands it and sets radial clearance or preload, so no adapter sleeve is involved on this bearing type.
Unit Quantity: 1 Pc.
The closest matches are the tapered-bore spindle-grade N1014s: FAG N1014-K-M1-SP with a brass cage and SKF N 1014 KTN9/SP with a polyamide cage, both built to SP precision. NTN N1014K and Koyo N1014K share the 70 x 110 x 20 mm size and 1:12 taper but are standard precision, not P4.
