SKF7003ACDGAP4ASuper-Precision Angular Contact Ball Bearing – 17 mm ID, 35 mm OD, 10 mm Width, Open, 25° Contact Angle, Light Preload

Product Description

What this part is

SKF 7003 ACDGA/P4A single-row super-precision angular contact ball bearing. Series: 70. Bore: 17 mm. Outside diameter: 35 mm. Width: 10 mm. Contact Angle: 25°. Open on both faces. Country of origin: Italy. GTIN: 7316570226102. Searchable forms include 7003ACDGAP4A, 7003-ACD-GA-P4A and 7003A5.

Decoding the designation

ACD: high-capacity D design at a 25° contact angle. GA: light preload on a universally matchable bearing. Precision Class: P4A, SKF’s super-precision class, equivalent to ABEC 7. The carton also carries the Fafnir equivalent 3MM9103WI CR SUL, in which 3MM confirms the 25° angle and CR the phenolic outer-ring land-riding cage.

What these specs mean in practice

A 25° contact angle carries substantially more thrust than a 15° bearing on the same envelope and runs at a lower speed limit, which is the trade a fixed-position or thrust-carrying spindle bearing is chosen for. Dynamic Load Rating: 6.55 kN. Static Load Rating: 3.55 kN. Limiting Speed: 38,000 rpm — a small-bore super-precision bearing reaches very high shaft speeds because the ball set is small and light.

Quantity and configuration

Universally matchable execution. 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.

Fitting notes

Straight bore on a cylindrical shaft seat. Preloaded execution, so Internal Clearance reads N/A. Cage: machined phenolic, riding on the outer ring land. Operating range: -40 °C to 120 °C.

Interchange guidance

Base number: 7003. FAG equivalent: B7003-E-T-P4S-UL. Fafnir equivalent: 3MM9103WI CR. NSK equivalent: 7003A5. SKF 7003 CDGA/P4A carries a 15° contact angle on the same 17 x 35 x 10 mm envelope and is a related size rather than a direct substitution.
