Flat steel - Import export

PVC-STEEL cylindrical and tapered rollers with one or two grooves rolled on the steel tube, driven by round belt links in series or individually connected to a transmission bar activated by the motor unit. PVC and PVC-STEEL rollers with flat or toothed polyamide resin PA or steel ACC pulley driven by tangential belt or belt links in series. The diagrams and tables on page 86 show the dimensional characteristics and minimum and maximum lengths of manufacture. The rollers for flat or toothed belts are produced in the following versions: with pinion integral to the jacket for continuous transport; with friction pulley for stockpiling transport and in the connection of machines operating at different speeds.

These isolators are the combination of a bearing and dampers in a single device; the latter are typically hysteretic dampers of steel and/or fluid viscous dampers. As such, they are characterized by a high damping capacity. The bearing can be multidirectional or unidirectional. Isolators can also include shock transmitters or mechanical fuse restraints. Experimental hysteretic cycles of a flat sliding isolator with steel hysteretic dampers. Installation of a flat sliding isolator with steel hysteretic dampers, at the Santuario 'Madonna delle Lacrime' of Siracusa. Flat sliding isolators with steel hysteretic dampers, installed in the railway lines "Caracas-Cua" and "La Encrucijada-Puerto Cabello", Venezuela.

The Rockflon series is a line of structural cylindrical bearings that generally allow rotations of ±2° around only one horizontal axis. They represent an evolution of the roller bearings, in which rotation movements take place through the rolling friction between two steel elements, one flat and the other a cylindrical rocker so that contact occurs along the cylinder generator line. The mutual sliding of 2 plane surfaces, one of stainless steel and the other of PTFE, ensures the bearing's translation movements. The use of Rocklon bearings is recommended whenever a high degree of stiffness against transverse rotations is considered necessary, a characteristic also typical of the series. Their elongated rectangular shape along the rotation axis is especially suitable if there is limited space available in the perpendicular direction to the rotation axis. Rockflon bearings are classified by two letters that have the following meaning: KF = Fixed Rockflon Bearing KU = Longitudinally guid
