SKF 7030 CDGA/P4A single-row super-precision angular contact ball bearing. Series: 70, high-capacity D design. Bore: 150 mm. Outside diameter: 225 mm. Width: 35 mm. Contact Angle: 15°. Open on both faces. Country of origin: Italy. Searchable forms include 7030CDGAP4A, 7030 CD/P4A DGA, 7030CDP4ADGA and 7030C.
CD: high-capacity D design at a 15° contact angle. GA: universally matchable, extra light preload. Precision Class: P4A, SKF’s super-precision tolerance class for machine tool spindles, equivalent to ABEC 7. GTIN: 7316570205855.
A 15° contact angle favours speed and radial stiffness over thrust capacity, which is why it is the standard choice for a driven spindle position. Extra light preload keeps frictional heat and running temperature down while still fixing the shaft axially. Dynamic Load Rating: 172 kN. Static Load Rating: 190 kN — in SKF’s 70-series light section the static figure sits above the dynamic figure, and that is the published relationship for this size.
One bearing. Universally matchable: bearings of this designation combine back-to-back, face-to-face or in tandem without shims or grinding, and the preload of the finished arrangement follows from the GA class.
Straight bore on a cylindrical shaft seat. Preloaded execution, so Internal Clearance reads N/A. Ball complement: 22 balls at 23.812 mm. Cage: machined, phenolic.
Base number: 7030. Fafnir spindle equivalent on the same envelope: 2MM9130WI. NSK equivalent: 7030CTYNSULP4. SKF 7030 CDGB/P4A and 7030 CDGC/P4A are the light and medium preload executions on the same 150 x 225 x 35 mm envelope, and 7030 ACD/P4A carries a 25° contact angle — each is a related size rather than a direct substitution.
