Product Description

What this part is

SKF 7015 ACD/P4ADGA is a matched set of two super-precision, high-capacity D design single row angular contact ball bearings from the SKF 70 series. The set is universally matched and can be arranged back-to-back, face-to-face or in tandem.

Decoding the designation

7015 — 70 series angular contact ball bearing, 75 mm bore, 115 mm outside diameter.

ACD — high-capacity D design with a 25° contact angle.

P4A — SKF precision class: ISO P4 dimensional accuracy with tighter running accuracy.

DGA — matched set of two bearings for universal matching, extra light preload.

What these specs mean in practice

Bore Diameter: 75 mm. Outside Diameter: 115 mm. Overall Width: 20 mm per bearing. Total Width: 40 mm (pair). Contact Angle: 25°. Precision Class: ABEC 7 / P4A. Preload: Extra light, 310 N (back-to-back or face-to-face). Axial stiffness: 200 N/µm (set). Dynamic Load Rating: 80,600 N (matched set). Static Load Rating: 93,000 N (matched set). Fatigue load limit: 3,900 N (set). Attainable speed, single bearing basis: 10,000 rpm grease; 16,000 rpm oil-air, before the SKF matched-set speed reduction factor. Ball diameter: 12.7 mm. Number of balls: 20 per bearing. Reference grease quantity: 8.4 cm³ per bearing. Bearing Material: Bearing steel. Closure Type: Open. The 25° angle gives higher axial load capacity and axial stiffness than a 15° execution.
