SKF 71911 CD/P4ADGC is a matched set of two super-precision, high-capacity D design, single row angular contact ball bearings from the SKF 719 extra-light series. The two bearings are ground for universal matching and can be mounted back-to-back, face-to-face or in tandem. Typical service is machine tool spindles and other high-accuracy shafts carrying combined radial and axial load.
719 — ISO dimension series 19, the extra-light cross-section.
11 — bore code, 11 x 5 = 55 mm bore.
CD — high-capacity D internal design with a 15° contact angle.
P4A — ISO P4 dimensional accuracy with running accuracy better than P4.
DG — set of two bearings for universal matching, with matched bore and outside diameters.
Bore Diameter: 55 mm. Outside Diameter: 80 mm. Overall Width: 26 mm for the two-bearing set, 13 mm per bearing. Contact Angle: 15°. The 15° angle favours speed and radial stiffness over axial capacity.
Dynamic load rating: 31,200 N for the set. Static load rating: 29,000 N for the set.
Precision Class: P4A. Number Of Rows: 2 (two single row bearings). Bearing Material: Bearing steel. Seal type: Open. Closure Type: Open. Bore Type: Straight. Item weight: 0.352 kg (0.78 lb) for the set.
Unit Quantity: 2 Pcs, one factory matched set of two bearings. Arrangement / Configuration: universal matching — back-to-back, face-to-face or tandem.
