Family specifications and selection conditions
| Product description | These super-precision ball bearings offer very high running accuracy and are well suited for screw drive applications. They are also beneficial in other applications, where safe radial and axial support is required, together with extremely precise axial guidance of the shaft. They provide a high degree of axial stiffness and can accommodate heavy axial loads in one direction, high speeds and rapid accelerations. |
|---|---|
| Manufacturer features | Very high running accuracy • High axial stiffness • High axial load carrying capacity in one direction • Universally matchable • Well suited for screw drive applications |
