A type of rolling-element bearing designed to accommodate misalignment and heavy radial loads.
Technical details and manufacturing context for Spherical Roller Bearings
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Bore Diameter | 20–400 mm | Standard series available up to 400 mmISO 15 |
| Outside Diameter | 52–600 mm | Matches bore size for standard seriesISO 15 |
| Width | 15–200 mm | Varies with seriesISO 15 |
| Dynamic Load Rating | 30–2000 kN | Higher values for larger sizesISO 76 |
| Static Load Rating | 20–3000 kN | Higher values for larger sizesISO 76 |
| Fatigue Load Limit | 1–300 kN | Depends on material and heat treatmentISO 76 |

Commonly used trade names and technical identifiers for Spherical Roller Bearings.
This component is essential for the following industrial systems and equipment:
| pressure: | Not pressure-rated (load capacity specified in kN), typical radial load capacity: 50-5000 kN depending on size |
| speed limit: | Up to 3000 rpm (depends on size, lubrication, and load) |
| temperature: | -30°C to +120°C (standard), up to +200°C with special materials/lubrication |
| misalignment accommodation: | Up to 2° shaft misalignment |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Standard series are available with bore diameters from 20 to 400 mm, per ISO 15. However, the exact bore size for a specific application must be confirmed with the manufacturer or supplier.
Yes, they have a self-aligning capability that allows them to compensate for shaft deflection and misalignment up to 1 to 2.5 degrees, per ISO 492. This is due to the spherical raceway on the outer ring.
Common materials include high-carbon chromium bearing steel (e.g., GCr15/52100) and case-hardened steel (e.g., 8620). The choice depends on the application requirements and must be verified with the manufacturer.
With standard grease, the operating temperature range is -40 to 200 °C, per ISO 15312. Special materials and lubricants may extend this range, but the actual limits must be confirmed with the supplier.
