Family specifications and selection conditions
| Product description | SKF indexing roller units are based on full complement cylindrical roller bearings. They have been developed for continuous furnaces of sintering and pelletizing plants. These ready-to-mount units are also suitable for heavy load applications where the direction of rotation is frequently reversed, or where rotational speeds are low. Also available on request with special sized bore and/or outside diameters, suitable for reworked shafts and housings. |
|---|---|
| Manufacturer features | Non-separable unit • Very thick walled outer ring for high loads • Sealed and filled with high-quality SKF grease • Virtually maintenance-free |
