9 Uses sealed-for-life ball bearings that allows for trouble-free life even in the harshest applications. Conveyors are a proven way to move bulk materials in practically every industry. Conveyors routinely operate at 90% capacity and can be operated 24/7, 365 days per year. Conveyors have a lower operating cost and can provide a higher return on investment than competitive methods. Maintenance is minimized and less labor is required. Material conveyed can range from very fine to large lumps of iron ore, stone, coal and wood products. The size of material is limited by the belt width used. Triple Labyrinth Seal Seal Cover Wide range of belt size design offers the following available product: exclusive bearing protection Triple CEMA C: 18" to 60". Labyrinth Seal CEMA D: 24" to 72". External shield deters CEMA E: 36" to 94". impurities from entering the bearing housing Rapid response for Made-to-Orders Flinger design removes contaminates away from Extremely low rolling the bearing housing by resistance that allows for lower centrifugal force operating cost Triple Labyrinth Roll gap meets CEMA.

10 Seal is grease filled and standards offers an additional Patent pending Idler end level of protection from welding allows for protection contaminants impacting against belt wear the bearing End-Disc Solid steel shaft the entire The contact lip seal Rubber Lip Seal length of the roll adds additional level of Ball Bearing Exceptional low TIR runout protection Shaft 9 & 7 Standard Steel Tubing, 1/4".
