Producer PerspectiveWet and Wild“ In the beginning, our plant was stocked by anotherbrand and some of them were lasting just threemonths! We run a lot of wet sand and they weren’tmaking the cut. ”Seal Power“ With other brands, the problems were directlyrelated to bearing failure. Sand was getting throughthe seals and into the can. I read about Superior’sseal in magazines and now I’m witnessing it! ”Competitive Comparison“ Comparing brand to brand, we get three – sometimesfour – times the life with Superior Idlers. They definitelyfit the bill! ”Plant Superintendent at Eastern Colorado Aggregates, La Junta, COPart Number GuideCEMARatingRollDiameterTroughingAngleIdlerTypeBeltWidthB, C, D, E, E, F 4” - 8” 20˚, 35˚, 45˚ See Below 18” - 120”12345CEMA Rating or Seriesu Specify either CEMA B, C, D, E, or FRoll Diameteru Specify either 4, 5, 6, 7, or 8 for the roll size diameterTroughing Angleu Specify either 20, 35, or 45 for the troughing angleIdler Typeu Specify the idler identification letter for the particular idler,you may need from the chart to the rightBelt Widthu Specify the belt widthIdler TypeE Troughing Idler Equal Length RollsEI Rubber Cushion Troughing IdlerEA Self-AlignerBA Bi-Directional Aligning IdlerRET Return IdlerFLT Flat Carrier IdlerFLTI Flat Carrier Rubber Cushion IdlerRETI Return Rubber Cushion IdlerRETU Urathon ® ReturnRETUSP Spiral Urathon ® Return RollRETA Return Self-Aligning Idler RollRETAI Return Self-Aligning Rubber Cushion IdlerRETV V-Return IdlerP Picking Idler Length RollsU Troughing Idler Unequal Length RollsCM Low-Profile Channel Mount IdlerCMI Channel Mount Impact Low Profile IdlerSM Low-Profile Standard Mount IdlerSMI Standard Mount Impact Low Profile IdlerGO Offset Troughing IdlerEW Wire Rope IdlerVPE Variable Pitch IdlerMOX Moxie ® RollCB CB504 SeriesLS Live ShaftLSB Live Shaft Beater
