Contact Angle: 15°. Cage Material: phenolic. Cage Type: outer-ring guided. Bearing Material: through-hardened chrome bearing steel. Precision Class: ABEC 5 / P5. Dynamic Load Rating: 111 kN (24,954 lbf). Static Load Rating: 114 kN (25,628 lbf). Limiting Speed: 6,300 rpm. Lubricant: oil. Operating temperature range: −30 °C to 120 °C. Item Weight: 7.8 lb. Harmonization Code: 8482.10.50.

Decoding the designation

Series: 7024 — single-row angular contact ball bearing, ISO 70 light series, 120 mm bore. Contact Angle: 15°, from the C. Cage Material: phenolic (laminated fabric), from the TC. Searchable forms of the number include 7024CTCC78, 7024-CTC-C78, 7024 CTC C78, 7024CTC and 7024C. The C78 suffix is carried as an MPN variant for search.

What these specs mean in practice

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 why 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, giving a working ceiling of 120 °C. ABEC 5 tolerances hold bore, outside diameter and raceway runout to precision limits, which keeps a spindle running true at speed.

Preload and arrangement

Mounting Arrangement: universal, so any two bearings of this designation pair in any orientation. Preload: light, set by the ground faces on clamp-up. Internal Clearance: N/A, since a preloaded set and a clearance class are alternatives to one another. Running Accuracy — Radial And Axial Runout: high precision.

Quantity and configuration

Unit Quantity: 1 Pc, a single bearing.

Interchange guidance

ISO envelope 7024 at 15°. Direct equivalents are other 7024 C bearings of matching cage and tolerance class, for example Fafnir 2MM9124WI-CR, FAG B7024-C-T-P5 and NSK 7024CTRP5. Same-envelope bearings at a different angle — 7024 AC at 25°, 7024 B at 40° — are related sizes.

Applications

Application Types: machine tool spindles, grinding heads, precision gearboxes, pump and compressor shafts, rotary tables.
