Manufacturer Ratings
Load-rating symbols are printed as each manufacturer writes them in its own catalogue, so the same quantity can carry a different symbol from brand to brand.
| Brand | Dynamic Load Rating | Static Load Rating | Additional Data |
|---|---|---|---|
| SKF 71900 CD/P4A | 2.51 kN | 1.1 kN | Contact angle: 15° |
Speed Ratings
Speed limits depend on sealing and lubrication, and definitions differ by manufacturer. Contact-sealed variants are normally greased for life and run slower. Always confirm the exact variant in the manufacturer's table.
| Brand | Grease open / shielded | Oil open | Reference | Limiting |
|---|---|---|---|---|
| SKF 71900 CD/P4A | 70,000 r/min | 110,000 r/min | — | — |

About This Type
Super-Precision angular contact ball bearings are made to tight tolerance classes for high-speed, high-accuracy rotation — first of all machine-tool spindles, but also precision pumps, compressors and measuring equipment.
These bearings are selected by precision class, contact angle (15° or 25° are the common standards) and preload rather than by load rating alone; the intended arrangement — back-to-back, face-to-face or tandem — must be fixed at ordering time. Universally matchable versions can be paired in any arrangement with the stated preload or clearance.
Cleanliness and correct preload decide the result: handle with gloves, mount in a clean environment, never wash out the preservative of sealed-for-life greased versions, and do not re-arrange or interchange rings between matched sets.
Series note: The 71 super-precision series is the light, high-speed design used for most machine-tool spindle applications.
