SKF 7024CTCC78G1 single row angular contact ball bearing. Bore: 120 mm. Outside diameter: 180 mm. Width: 28 mm. Series: 70. Open on both faces, straight bore, chrome steel rings and balls. Precision class ABEC 5 / P5.
7024: ISO 70 series, 120 mm bore on the 180 mm outside diameter and 28 mm width envelope. C: 15° contact angle. TC, C78 and G1 are legacy North American execution and tolerance suffixes carried on the ring and the carton, and they are recorded here as part of the full part number.
A 15° contact angle runs faster and takes less thrust than a 25° angle of the same envelope, which suits high-speed spindle positions. ABEC 5 / P5 holds bore, outside diameter and running accuracy to a tighter band than a standard-tolerance bearing, giving closer shaft location and lower running vibration.
Phenolic window cage. Phenolic runs quieter and lighter than brass at high speed and holds oil in the fabric, which suits sustained high-speed spindle duty.
One bearing. Mass: 2.40 kg (5.30 lbs).
The 7024 envelope is 120 x 180 x 28 mm. Same-envelope equivalent at 15°: Fafnir 2MM9124WI CR. SKF’s current super-precision equivalents on this envelope are 7024 CD/P4A at 15° and 7024 ACD/P4A at 25°, both held to the tighter P4 class. Searchable forms: 7024CTCC78G1, 7024 C TC C78 G1, 7024-CTC-C78-G1, 7024CTCC78, 7024C, 7024.
