SKF 7018 CGA/P4 super-precision angular contact ball bearing, single row, 90 x 140 x 24 mm, universally matchable. Unit Quantity: 1 Pc. 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.
Bore Diameter: 90 mm (3.5433 in). Outside Diameter: 140 mm (5.5118 in). Width: 24 mm (0.9449 in). Contact Angle: 15°. Precision Class: ABEC 7 / P4. Preload: Extra light (GA). Rolling Elements: Steel balls, single row. Closure Type: Open both faces. Series: ISO 70. Base Number: 7018.
