BNTB 326247/HB1
Indexing roller unitSKF 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.
- Non-separable unit
- Very thick walled outer ring for high loads
- Sealed and filled with high-quality SKF grease
- Virtually maintenance-free
