    Interroll has presented tapered elements for its curved roller conveyors that offer optimized fixing.Installing a roller conveyor curve is all about the details, which can have a large impact on the smooth flow of materials.

    As is the case with cylindrical rollers, the material being conveyed is moved outward from speeds of around 0.8 meters per second, because the centrifugal force becomes greater than the frictional force.If the tapered elements were locked from the outside, interfering edges or points of interference would appear.

    NTN has introduced its ULTAGE spherical roller bearings. ULTAGE bearings contain an optimized surface finish and incorporate a window-type pressed steel cage without the center guide ring for higher rigidity, stability and better lubrication flow throughout the bearing. These design features allow for 20 percent higher limiting speeds when compared to conventional designs, reducing operating temperatures that extend lubrication intervals and keep production lines running longer.
