An SKF 7024 CTC C78 precision angular contact ball bearing in the 120 x 180 x 28 mm envelope, ISO base number 7024. Single row, 15° contact angle, open on both faces.
7024 — single-row angular contact ball bearing, ISO 70 light series, 120 mm bore.
C — 15° contact angle.
TC — phenolic (laminated fabric) ball cage.
A single-row angular contact ball bearing takes thrust in one direction, combined with a radial load. At 15° the thrust capacity is lower than a 25° or 40° bearing of the same size, and the speed capability and stiffness-per-watt are higher, which is the reason 15° dominates high-speed spindle positions. The light 70-series section holds mass and centrifugal ball load down at speed. A phenolic cage is dimensionally stable, quiet, and holds oil within the cage material, with a practical temperature ceiling around 120 °C.
Bore: 120 mm (4.724 in)
Outside diameter: 180 mm (7.087 in)
Width: 28 mm (1.102 in)
Rows: 1
Contact angle: 15°
Series: ISO 70 light
Cage material: phenolic
Rolling elements: balls
Closure: open, both faces
Sale unit is 1 Pc, a single bearing. The designation carries no duplex or preload code, so it is an individual bearing rather than half of a ground matched set.
The inner ring takes a light interference fit on a ground shaft seat and the outer ring a close fit in the housing bore, each clamped against a face square to the axis. Locating a shaft in both directions calls for a second bearing opposed to this one; two 7024 C bearings set back-to-back give the stiffest span.
ISO envelope 7024 at 15°. Direct equivalents are other 7024 C bearings of matching cage and tolerance class, for example Fafnir 2MM9124WI. Same-envelope bearings at a different angle — 7024 AC at 25°, 7024 B at 40° — are related sizes, not interchanges.
