SKF7010ACDP4ADGASuper-Precision Angular Contact Ball Bearing – 50 mm ID, 80 mm OD, 16 mm Width, Open, 25°, Light Preload, ABEC 7

Product Description

What this part is

SKF 7010 ACDGA/P4A super-precision angular contact ball bearing. Bore: 50 mm. Outside diameter: 80 mm. Width: 16 mm. Series: 7000, light section. Base number: 7010. Single row, open, bearing steel rings and balls. Searchable forms of the designation include 7010 ACDGA/P4A, 7010-ACDGA/P4A, 7010ACDP4ADGA, 7010 ACD/P4A DGA and 7010A5. GTIN: 7316570650259.

Decoding the designation

Contact Angle: 25°, from the ACD position. Cage: machined fabric-base laminate phenolic, outer-ring guided, from the D position in SKF’s super-precision scheme. Preload: light, from the DGA position. Precision Class: ISO P4 / ABEC 7, from P4A. Universally matchable, so any two pieces of this designation pair up in any orientation.

What these specs mean in practice

A 25° contact angle carries more thrust and less speed than a 15° bearing of the same envelope, which suits spindles that see substantial axial cutting load. Dynamic Load Rating: 26.6 kN. Static Load Rating: 22.8 kN. Limiting Speed: 18,000 rpm. Operating temperature: –30 to +100 °C. Mass: 0.251 kg. The machined phenolic cage is light and quiet at speed and suits oil-mist and oil-air lubrication. ISO P4 tolerances give tighter running accuracy and lower running vibration than standard class.

Quantity and configuration

One bearing. Light preload is ground into the ring faces, so pairing two pieces and clamping them solid sets the preload without shims or spacers.

Fitting notes

Rings are clamped against the shaft shoulder and the housing shoulder. Because preload is ground in, this bearing carries no radial internal clearance class. Running accuracy, radial and axial runout: P4.

Interchange guidance

Equivalents at the same envelope, angle and light preload: Fafnir 3MM9110WI-DUL, GMN S6010 E TA A7, FAG B7010-E-T-P4S-UL. The 7010 CDGA/P4A is a related size at 15° and carries different thrust and speed figures. The 7010 ACDGB/P4A and 7010 ACDGC/P4A are the same envelope at medium and heavy preload.
