Series 40,000 and 70,000 Catenary Belt Conveyor Idlers Link-Belt Series 40,000 and 70,000 Catenary Belt Conveyor Idlers combine the proven capabilities of the Link-Belt roll design with the benefits of a catenary suspension to form a smooth natural trough and ideal load conveying surface. Series 40,000 and 70,000 Catenary Idlers are manufactured to withstand heavy impact at loading and transfer points as required by wide belts through 96-inch width. Superior performance and proven dependability are the result of rugged roll construction, exclusive labyrinth seal design and high-capacity “sealed for life” tapered roller bearings. Especially suited to loading areas or transfer points in reclaiming installations where high impact loads must be absorbed, these catenary idlers have the design and built-in ability to adjust under varying loading conditions. The Series 40,000 exclusive outboard seal effectively protects bearings three ways… a triple lip nitrile rubber primary seal… triple labyrinth… and grease-filled clearances. This design makes the idlers impervious to moisture and contaminants, extending idler life. The complete line of Link-Belt Series 40,000 Catenary Belt Conveyor Idlers includes 35° 3-roll Troughing Idlers, 55° 5-roll Impact Idlers, and 10° and 15° 2-roll V-Return Idlers. V-Return Idlers are supplied with steel rolls. This full range of idlers provides the design engineer with components required to select an efficient material conveying system. All Series 40,000 idlers are available for belt widths from 36 up to 96-inches and can be supplied with either 6- or 7-inch diameter rolls. Prior to shipping, rolls are protected by a baked on polymeric powder coating. When load carrying requirements exceed standard limitations, the Series 70,000 Catenary Idler provides more than double the capacity of the Series 40,000 Belt Conveyor Idler. Catenary Chain Connecting Devices are an economical and effective means for suspension of 3-roll Troughing Idlers and 2-roll V-Return Idlers. A bar link arrangement for 5-roll Impact Idlers is also available. There are various other Connecting Devices available for the Link-Belt Catenary Idlers which allow the conveyor designer complete freedom in choice of support structures. Details can be furnished upon request. Quick Disconnect Devices for Syntron Material Handling Catenary Idlers can also be provided, which permit operators to drop an idler out of service without stopping the conveyor. …featuring impact resistance and load adaptability for smooth c
