A matched pair of single-row super-precision angular contact ball bearings in the 70-series, 65 mm bore, 100 mm outside diameter, 18 mm width per bearing. The rings are ground as a set for back-to-back mounting at a defined light preload.
7013 — single-row angular contact ball bearing, 65 mm bore, 70 dimension series.
AC — 25° contact angle in the SKF scheme.
CD — super-precision execution.
DGB — matched pair, back-to-back, light preload.
P4A — ABEC 7 precision class, SKF super-precision tolerance.
A 25° contact angle carries substantially more thrust and gives higher axial stiffness than a 15° execution of the same 65 x 100 x 18 mm envelope, in exchange for a lower speed ceiling. Light preload gives the set defined axial stiffness while keeping friction and running temperature moderate. Back-to-back mounting spreads the load lines outward, which resists moment loads and holds the shaft square under overhung tooling. ABEC 7 running accuracy holds the radial and axial runout that spindle work depends on.
2 Pcs, one matched pair. Total mounted width of the pair is 36 mm.
The pair mounts in its ground orientation with the etched face markings aligned so the two outer rings meet at their narrow faces. Both rings are clamped fully home, so the preload comes off the ground faces rather than off clamp force, and rings are pressed by the ring being fitted rather than through the balls or cage.
25° ABEC 7 back-to-back 7013-size pairs in other makers’ schemes: NSK 7013A5TRDUM and Fafnir 3MM9113WI DUM – both medium preload, not light. Near parts: SKF 7013 CDGB/P4A – 15° vs 25°; SKF 7013 ACDGA/P4A – extra light preload; single universally ground 7013 ACDGA/HCP4A executions – not a matched pair.
