Self‑Aligning Geometry: The dual‑row ball arrangement and spherical outer raceway allow angular misalignment between shaft and housing.
Misalignment Compensation: The internal geometry accommodates mounting deviations without increasing friction or generating edge stresses.
C3 Clearance: The increased internal clearance supports thermal expansion and higher operating speeds under standard load conditions.
Steel Cage: The pressed steel cage maintains ball spacing and structural stability during continuous rotation.
Open Configuration: The absence of sealing elements allows external lubrication and direct inspection of the rolling elements.
The 1303 C3 RICH bearing is a self‑aligning ball bearing with dimensions 17 × 47 × 14 mm. Its spherical outer raceway enables compensation for shaft or housing misalignment, while the C3 clearance supports applications with increased thermal expansion or rotational speed.
Transparency Note: This bearing is manufactured under the RICH brand. All technical data refer exclusively to the RICH 1303 C3 model and do not imply association with other manufacturers.
