Universally matched pair of SKF 7006 ACD/P4A DGA super-precision angular contact ball bearings. Single row each, 30 mm bore, 55 mm outside diameter, 13 mm width, open on both faces, with a machined phenolic cage riding on the outer ring land. Unit Quantity: 2 Pcs, one matched set, 26 mm total width.
7006 — ISO 70 dimension series with bore code 06, giving a 30 mm bore.
AC — 25° contact angle in the SKF scheme.
D — machined fabric-base laminate phenolic cage.
P4A — SKF’s super-precision tolerance class.
DGA — matched set at extra light preload.
Bore Diameter: 30 mm. Outside Diameter: 55 mm. Width: 13 mm per bearing. Total Width: 26 mm. Contact Angle: 25°. Number Of Rows: 1 per bearing. Rolling Elements: Steel ball. Cage Material: Phenolic. Closure Type: Open. Preload: Extra light. Dynamic Load Rating: 16.8 kN per bearing. Static Load Rating: 10.3 kN per bearing. Limiting Speed: 28,000 rpm. Series: 7000 (ISO 70). Arrangement: universally ground matched pair.
Envelope: 30 x 55 x 13 mm each. The rings are universally ground, so the pair can be arranged back-to-back, face-to-face or in tandem. The DGA extra light preload arises when the rings are clamped together.
Closest numbers at the same size, angle and cage, supplied at light rather than extra light preload: FAG B7006-E-T-P4S-DUL, NSK 7006A5TYNDULP4, Fafnir 3MM9106WI-DUL and RHP 7006ETDULP4. SKF 7006 ACD/P4ADGB is the same bearing at light preload. SKF 7006 CD/P4ADGA has the same 30 x 55 x 13 mm size at a 15° angle.
Bore 30 mm, outside diameter 55 mm, width 13 mm per bearing, 26 mm total width for the pair.
Contact angle 25° (AC). Extra light preload (DGA).
Dynamic Load Rating 16.8 kN and Static Load Rating 10.3 kN per bearing, limiting speed 28,000 rpm.
