Family specifications and selection conditions
| Product description | CARB toroidal roller bearings are unique: as well as accommodating misalignment without increased stress levels, they also provide frictionless axial movement within the bearing in the non-locating position in self-aligning bearing arrangements. Being SKF Explorer bearings, they can accommodate higher load levels and provide significantly extended service life. |
|---|---|
| Manufacturer features | Accommodate misalignment and axial displacement within the bearing • High radial load carrying capacity • Provide frictionless axial movement • Long bearing system life • Reduce noise and vibration levels |
