Family specifications and selection conditions
| Product description | These matched sets of two super-precision, high-capacity, D design, single row angular contact ball bearings are available in a variety of arrangements. They are designed for high-load capacity and relatively high speed operation and, compared to the equivalent SKF B and E design high-speed bearings, are best suited for heavier loads. |
|---|---|
| Manufacturer features | Very high running accuracy • Very high load carrying capacity |
