SKF 7013 ACD/P4AQBCA is a matched set of super-precision, high-capacity single row angular contact ball bearings in the 70 series, with a 25° contact angle and extra light preload, arranged tandem back-to-back. The factory QBCA set is four bearings: two tandem pairs mounted back-to-back, for high axial and radial stiffness in machine tool spindles.
70 — ISO dimension series 10, light section.
13 — bore code, 13 x 5 = 65 mm bore.
ACD — 25° contact angle, high-capacity D design.
P4A — SKF tolerance class: ISO P4 dimensional accuracy with ISO P2 running accuracy.
QBC — matched set of four bearings, tandem back-to-back arrangement.
A — extra light preload.
