BNTB 326247/HB1

Indexing roller unit
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.

  • Non-separable unit
  • Very thick walled outer ring for high loads
  • Sealed and filled with high-quality SKF grease
  • Virtually maintenance-free
