4.2.4 Points of Notice About Roller Type

Figure 4.17 shows the roller types and ways of guiding used in conveyor chains.

  1. First of all, consider if an R-roller will meet the operating conditions.
  2. An S-roller is designed to relieve shock caused by sprocket engagement, but when the conveyed objects are light and the conveyor length is short, an S-roller may be used.
  3. An F-roller is used primarily to prevent snaking in large pitch conveyor chains. Because its flange operates and wears against the side rail, it is not the roller of choice to convey heavy objects or bulk material or to operate at high speeds.
