The Link-belt(r) F5000 trough idler assemblies are recommended where bulk conveyor loads exceed CEMA E ratings for the highest capacities and toughest materials.
The heavy duty design which incorporates 1.75-inch (45mm) diameter precision tapered roller bearings offers significantly higher load ratings and impact capabilities than competitive belt idlers.
F5000 idlers are available in belt widths from 1200 to 3000mm's and with rolls of 178 or 203mm diameter, trough angles 20, 35 & 45 degrees. The F5000 idlers are sealed for life with a grease filled, triple horizontal labyrinth seal that repels contaminants, extends bearing life and eliminates the need for relubrication.
The primary seal is a nitrile rubber triple lip contact member and the rear seal is a non-contact metallic seal. To resist water, the lubricant used is a water resistant, grade 2, lithium-based grease.
The F5000 idler features a solid shaft that is 45mm diameter at the bearings. Optional stepped shafts with diameters of 50mm and 62mm are available.
A polymeric powder coating (Corvel Gray)protects the F5000 rollers and frames from corrosion. The coating is applied following a three-stage phosphate cleaning operation and is then baked on at high temperatures to provide resistance to abrasive elements. Assembly hardware is electro-zinc plated to ensure extended service
The inverted angle frame base of the F5000 idler is constructed of ASTM A-36 steel and is designed to shed material build-up. Slotted footstraps ensure quick, easy mounting and alignment.
The heavy duty, die formed, steel end brackets have a contoured profile and generous clearances to prevent spilled materials becoming jammed and impeding the rotation of the rollers. All idler frames and rolls are welded in accordance with AWS D1.1 specifications for structural welds.
