Designed to meet or exceed the load limits established by the CONVEYOR Equipment Manufacturers Association (CEMA) . Legend:TroughingTransitionImpactReturnRu bber DiscHeadPulleySnubPulleyBendPulleyTake-U pPulleyTailPulleyImpact Troughing IDLERS are a special version of troughing IDLERS , providing a roll with cushioning rubber discs to lessen the belt damage due to impact from materials being loaded onto the belt . The frame is additionally reinforced to increase ridgidity.

4 Self-Aligning IDLERS , troughing, flat and return, assist in keeping the CONVEYOR belt centered on the CONVEYOR when temporary or transient conditions could result in belt misalignment .Unequal Troughing (Picking) IDLERS are used to reduce the height to aid in magnetic separation, picking, sorting, or manual separation .The inclined roll ends turn up the belt to minimize spillage . Rubber disc rolls are also available . The load ratings are greatly reduced from standard troughing IDLERS because most of the weight is on the long center roll .Channel Inset Troughing IDLERS are attached to a channel CONVEYOR or other vertical surface by side mounting.

5 They are used in tight clearance areas requiring a low profile . Rubber disc rolls are also available . Designed to interchange with other major brands .Flat Carrier Idler applications include picking, sorting, feeders, and package handling . Rubber disc rolls are also available . Load ratings are the same as return rolls and are greatly reduced from that of troughing IDLERS because of the long shaft length and having only two bearings .Return IDLERS support the belt during the return path and meet or exceed the CEMA load requirements . Return and flat IDLERS (R, RRD, F, FRD, CIR, CIRRD, CIF, & CIFRD types) in B, C, D, and E series should not be used in a snub pulley type application.

6 Shafting, bearings, and brackets may be overloaded in such applications leading to premature failure . Steel Tube used when materials are not sticky, corrosive, or abrasive . Rubber Disc used when sticky, corrosive, or abrasive materials are present . Massed end discs are standard .Covered Rolls used when very sticky or abrasive materials are present .The following is a simplified CONVEYOR used to illustrate basic belt CONVEYOR components . Many variations of elevation, loading, discharge, IDLERS and idler spacing, pulleys, and accessories are possible . Live Shaft IDLERS with pillow block bearings provide an increased loading capacity . Available in solid and spaced rubber discs rolls and steel rolls.
