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 | Fatigue Load Limit |
|---|---|---|---|
| SKF 3200 ATN9 | 7.61 kN | 4.3 kN | 0.183 kN |
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 3200 ATN9 | — | — | 26,000 r/min | 24,000 r/min |

About This Type
Angular contact ball bearings carry combined radial and axial loads; the contact angle lets a single bearing take axial load in one direction. They run at high speed and are the standard choice for machine-tool spindles, pumps, compressors, gearboxes and electric motors.
A single bearing carries axial load in one direction only, so two bearings are mounted back-to-back, face-to-face or in tandem — or a double-row 32/33 series bearing is used instead. A larger contact angle (commonly 40° rather than 30°, or 25° rather than 15°) raises axial capacity at the cost of radial capacity and speed. Axial clearance is not a catalogue suffix here: it is set by the paired configuration and the mounting adjustment, and universally matched bearings are supplied ground for a defined clearance or preload.
Orientation decides everything: in a back-to-back pair the load lines diverge and the arrangement is stiff against tilting; face-to-face tolerates more misalignment; tandem doubles the thrust capacity in one direction. Mount so that the thrust acts against the high shoulder of the outer ring, keep matched sets together, and apply the manufacturer’s preload or clearance setting — a loose pair loses the stiffness the arrangement was chosen for.
Series note: The 32 series is the double-row design: it takes axial load in both directions, so no paired mounting is needed.
