Maximum operating temperature: 120 °C. Harmonization Code: 8482.10.50.
Series: 7220 — single-row angular contact ball bearing, 72 medium series, 100 mm bore. Contact Angle: 15°, from the C. Cage Material: phenolic fabric-laminate, from the TC. Searchable forms of the number include 7220CTCC78, 7220-CTC-C78, 7220 CTC C78, 7220CTC and 7220C. The C78 suffix is carried as an MPN variant for search.
A single-row angular contact ball bearing carries thrust in one direction together with a radial load. At 15° the thrust capacity is lower than a 25° or 40° bearing of the same envelope and the speed capability is higher, which is why 15° is the usual choice at the fast end of a spindle. The 72 medium section takes more load than a 70 light bearing of the same bore, in exchange for a larger outside diameter and greater mass. A phenolic window cage is quiet and dimensionally stable and holds oil in the cage body, giving a working ceiling of 120 °C. ABEC 5 tolerances hold bore, outside diameter and raceway runout to precision limits.
Unit Quantity: 1 Pc, a single bearing. Arrangement / Configuration: single bearing.
ISO envelope 7220 at 15°. Direct equivalents are other 7220 C bearings of matching cage and tolerance class, for example Fafnir 2MM220WI, NSK 7220CTY and 7220-C-P5. Same-envelope bearings at another angle — 7220 AC at 25°, 7220 B at 40° — are related sizes.
Application Types: machine tool spindles, grinding heads, precision gearboxes, pump and compressor shafts.
