TECHNICAL DATA SHEET EVO® High Speed Roller Cradle The EVO® High Speed Roller Cradle is designed to provide belt support in transfer points where belt speeds exceed the operating limits of ordinary impact bar belt support cradles. 1. The first X indicates CEMA class: D = CEMA “D” E = CEMA “E” 2. The next X indicates roll diameter: 5 = 5 inches 6 = 6 inches 7 = 7 inches 3. The next X indicates roll manufacturer: P = PPI 4. The next XX indicates belt width: CEMA D is available in 30–72” CEMA E is available in 36–72” 5. The next XX indicates trough angle: 20 = 20 degrees 35 = 35 degrees 6. The next X indicates stringer width: S = Standard W = Wide Designed and engineered for high speed/high tonnage belts. Designed to withstand the highest belt speeds achievable with heavy-duty impact rolls. Slide-out/slide-in roller frames allow idler service without the need to raise belt or remove adjacent idlers. Close roll spacing allows effective belt sealing and superior belt support. Innovative upper connector brackets link idlers together throughout the load zone, allowing them to work together as a unified structure. Elastomer bar suspension absorbs shocks from impact maximizing the life of the belt support structure and rolling components. Accommodates belt widths and troughing angles for CEMA, DIN, SABS and other conveyor standards. Assemblies are supplied with impact rolls from Precision Pulley and Idler.
