Link-Belt ® Tapered Bearing Idler RollsSealed for life roll design ensures extended, trouble-free service lifefor CEMA Series D, E and F models. . .Link-Belt Tapered Bearing Idler Rolls are perfectlysuited for continuous material handling operationsmoving massive volumes of tough, abrasivematerials such as coal, iron ore, and rock products.Boasting load ratings that exceed CEMA requirements,this rugged line is available in CEMA D, E and Fseries models.Link-Belt sealed for life tapered roller bearing idlersfeature factory-lubricated and sealed for life rollswhich eliminates relubrication maintenance costs.In the CEMA E and F series rolls, bearing life isextended by using solid, cold drawn steel shaftsto minimize deflection and increase load ratings.Link-Belt D-7000 rolls feature stub shaft technology,discussed in detail on the following page.Link-Belt CEMA E and F series rolls are designed tohandle the heaviest, most abrasive materials. Theyfeature a premium quality Delrin triple horizontallabyrinth outer seal that protects the precisiontapered roller bearings in several ways. The outerdeflector cap (flinger) features a 90˚ contoured lipto deflect material away from the roll end. Triplehorizontal, grease-filled labyrinths and contact primaryseals, along with rear non-contact seals,ensure against the ingress of performance-inhibitingcontaminants. Outer adjusting nuts are zinc-platedmachined steel to minimize corrosion.Link-Belt rolls are protected from corrosion by a polymericpowder coating baked on at high temperatures to provideresistance to abrasive elements. Assembly hardware iselectro-zinc plated to ensure extended service.

Link-Belt ® D7000 SST II Idler RollsSignificant advancements in tapered roller bearing technology,quality, performance, reliability and value. . .First introduced in 2002, the patented Link-BeltD7000 SST stub shaft tapered bearing idler rollrepresented the first significant advancement inroll technology in more than 40 years. In 2004,FMC engineers released the next generation inthis revolutionary series, the SST II. The SST IIdelivers significantly longer service life withoutcompromising the significant technology advancementsof the original design.In addition to proprietary pressed head technology,the SST II features a new, proprietary quadtapered roller bearing (developed exclusively forthe SST II) that delivers a 20 percent longer servicelife than commercially available bearings.A new, advanced sealed forever sealing system hasalso been incorporated to repel contaminants,extend bearing life and eliminate the need forrelubrication. FMC’s engineers redesigned the sealto decrease the amount of friction introduced intothe roll, resulting in a new, triple-lip contact sealwith lower torque and less drag. The lips of the sealrub against the shaft, taking full advantage of thenear zero TIR (total indicator runout).Ratings exceed CEMA D standards in all sizes andare constant for all belt widths, decreasing only bythe weight of the roll. Because shaft slope throughthe bearings is minimized, the quad bearing / stubshaft design improves service life over thru-shaftdesigns with no reduction of bearing life underapplied loads.●Link-Belt ® D7000 SST IICema D Idler RollsFMC proprietary quad tapered rollerbearings with 20% longer servicelife than commercially availablequad tapered roller bearings.D7000Rugged ductile-iron, interference-fit headpresses into shell eliminating welding and thepotential problems that go with it.Standard zinc-plated stub shaft minimizesshaft slope with no reduction of bearinglife under applied loads.Low-friction triple lip shaft contact sealprevents life robbing contaminants fromentering the bearing cavity.●●Used in conjunction with FMC’szinc-plated stub shaft, this uniquedesign offers significantly higher loadratings, impact capabilities and servicelife than competitive belt idlers.Advanced sealing system repelscontaminants, extends bearing lifeand eliminates the need forrelubrication.Quad tapered roller bearings deliversignificantly higher load ratings andimpact capabilities.Rear cap completes the “Sealed Forever” grease reservoirand eliminates rear seal drag and grease leakage.● Interference-fit head presses into thehigh-tolerance shell, eliminatingwelding and associated problems.● Universal retrofit capability.7
