An SKF 7018 CGA/P4 super-precision angular contact ball bearing, single row, universally matchable. Steel rings, steel balls, open on both faces.
70 — ISO 70 dimension series; bore code 18 gives a 90 mm bore.
C — 15° contact angle in SKF’s scheme.
GA — universally matchable design, extra light preload.
/P4 — ISO tolerance class 4, equivalent to ABEC 7.
A 15° contact angle favours speed and radial stiffness over thrust capacity, which is the standard choice for a spindle front position. Extra light preload holds a low running temperature and low frictional torque, at some cost in axial stiffness. Universal matching means the ring faces are flush-ground to a common height, so any two rings of this designation seat together back-to-back, face-to-face or in tandem and reach the marked preload with no shim stack. P4 tolerances hold the bore, outside diameter and running accuracy to ISO class 4.
Bore: 90 mm (3.5433 in). Outside diameter: 140 mm (5.5118 in). Width: 24 mm (0.9449 in). Contact angle: 15°. Precision class: P4 (ABEC 7). Preload: extra light (GA). Rolling elements: steel balls, single row. Closure: open both faces.
1 Pc, a universally matchable single at extra light preload.
ISO base number 7018. Searchable forms are 7018 CGA/P4, 7018CGA/P4, 7018CGAP4, 7018-CGA-P4 and 7018 CGA P4. SKF 7018 ACGA/P4 is the same size at 25°. SKF 7018 CGB/P4 and 7018 CGC/P4 are the same bearing at light and medium preload.
