SKF 7215 CD/P4 DGA super-precision angular contact ball bearing. Series: 72, light section. Base number: 7215. Bore: 75 mm. Outside diameter: 130 mm. Width: 25 mm. Single row, straight bore, open on both faces. Searchable variants of the designation: 7215CD/P4DGA, 7215 CD P4 DGA, 7215CDP4DGA, 7215-C-P4-DGA, 7215CP4DGA, 7215C.
Contact Angle: 15°. Precision Class: P4, equivalent to ABEC 7. Preload: light. Cage: machined, fabric-reinforced phenolic, rated to 120 °C.
A 15° contact angle favours speed and radial rigidity over thrust capacity, which is why this execution is standard in machine tool spindles and precision grinders. Light preload holds running accuracy with lower heat generation than a medium or heavy setting. Basic dynamic load rating: 74.1 kN. Basic static load rating: 64.0 kN. Limiting speed: 13000 rpm.
Two bearings. Unit Quantity: 2 Pcs. Universally matchable execution, ground to the light preload class. Internal Clearance: N/A — the bearings are preload-set, not clearance-set.
New old stock, open box. Item weight 2.55 lbs per bearing.
Mounting is by interference on the inner ring seat with the outer ring located axially in the housing. Oil or grease lubrication both suit the phenolic cage. Operating range: -30 °C to 120 °C.
Same-spec equivalents: Fafnir 2MM215WI-DUL, NSK 7215CTYNDULP4. Related size: 7215 ACD/P4A carries a 25° contact angle and a different thrust capacity.
