SKF 7003 CD/P4ADT is a matched set of two super-precision, high-capacity D design single row angular contact ball bearings from the SKF 70 series, matched for tandem mounting. Both bearings face the same direction and share the axial load in one direction. Not a double-row bearing.
7003 — 70 series angular contact ball bearing, 17 mm bore, 35 mm outside diameter.
CD — high-capacity D design with a 15° contact angle.
P4A — SKF precision class: ISO P4 dimensional accuracy with tighter running accuracy.
DT — matched set of two bearings for tandem arrangement.
Bore Diameter: 17 mm. Outside Diameter: 35 mm. Overall Width: 10 mm per bearing. Total Width: 20 mm (pair). Contact Angle: 15°. Precision Class: ABEC 7 / P4A. Mounting Arrangement: Tandem. Dynamic Load Rating: 11,100 N (matched set). Static Load Rating: 6,550 N (matched set). Fatigue load limit: 275 N (set). Attainable speed, single bearing basis: 50,000 rpm grease; 75,000 rpm oil-air, before the SKF matched-set speed reduction factor. Ball diameter: 5.556 mm. Number of balls: 12 per bearing. Reference grease quantity: 0.54 cm³ per bearing. Bearing Material: Bearing steel. Closure Type: Open.
Inner ring shoulder diameter d1: 22.6 mm. Outer ring shoulder diameter D1: 29.3 mm. Chamfer r1,2 min: 0.3 mm. Chamfer r3,4 min: 0.2 mm. Shaft abutment da/db min: 19 mm. Housing abutment Da max: 33 mm; Db max: 33.6 mm. Fillet radius ra max: 0.3 mm; rb max: 0.2 mm. Oil nozzle position dn: 23.7 mm.
Unit Quantity: 2 Pcs. One tandem-matched set of two bearings.
Same envelope and 15° angle, tandem set: FAG B7003-C-T-P4S-DT, NSK 7003CTYNDTP4, Timken/Fafnir 2MM9103WI DT. Cage execution and exact class vary by maker.
