Self-centering conveyor idler roller
18" - 72" | D7000 series FMC Technologies, Material Handling Solutions

The revolutionary Link-Belt® D7000 SST II™ Tapered Bearing Idler is a quad bearing belt conveyor idler that delivers significant advancements in technology, quality, performance, reliability and value through stub shaft design. First introduced in 2002, the patented Link-Belt D7000 SST idler delivers continuous service capabilities, load ratings that exceed current CEMA standards, zero maintenance requirements and universal retrofit capabilities. Plus, recent design improvements have resulted in a significantly longer service life.

New Proprietary Roller Bearing Technology

Since the introduction of the first SST idler in 2002, FMC Technologies has continued to focus on the importance of bearings in idler roll design. As a result, the SST II features a new, proprietary bearing developed exclusively for the Link-Belt D7000 SST II idlers. The new FMC bearing has a 20 percent longer service life than commercially available bearings. Used in conjunction with the zinc-plated stub shaft, this unique design offers significantly higher load ratings and impact capabilities than competitive belt idlers. The ratings exceed CEMA D standards in all sizes and are constant for all belt widths, decreasing only by the weight of the roll. Because shaft slope through the bearings is minimized, the proprietary bearing/stub shaft design also improves service life over thru-shaft designs, with no reduction of bearing life under applied loads. The SST II Troughed Idler has load ratings that are 37 percent higher than CEMA specifications, while the SST II Return Idler has load ratings that are more than five times greater than CEMA specifications.
