Rollers are conveyor

Rollers are intended for maintenance of a tape in tape conveyors. The roller feedwell from a steel pipe in accordance with GOST 10704, a shaft from the calibrated steel in accordance with GOST 7417 or hot-rolled steel in accordance with GOST 2590, a lock ring from steel of 65 G in accordance with GOST 13942. Connection of the feedwell of a roller and the case of bearing knot can be both in welded, and in valtsovanny execution. The case of bearing knot - stamped - from a steel sheet in accordance with GOST 9045. The protection cover is manufactured of a steel sheet in accordance with GOST 9045 and installed on an external labyrinth that provides reliable protection of bearing knot against mechanical damages and hit of abrasives and dust. The rollers made by JSC PIER Plant have such distinctive features as: Own original bearing knot (the bearing in accordance with GOST 8338 or upon the demand of the customer in accordance with GOST 7242) is filled with litol-24 greasing in accordance with GOST 21150 or another similar on properties; Specially calculated labyrinth consolidation: external and internal three-channel labyrinths, are made of frost-resistant polypropylene which temperature borders of use from -35 °C to +50 °C; labyrinth consolidation is also filled with greasing; At the expense of lower weight of rollers, in comparison with rollers of other producers, the starting effort to the conveyor considerably decreases that reduces wear of details of the conveyor and especially conveyer belt. The modernized rollers of JSC PIER Plant possess the increased stock of service life of bearing knot. Protection of the bearing against hit of dust and moisture, is provided with two additional details: A boot - pressurizing labyrinths; The Reflector - carrying out function of the shock-absorber of blows of various foreign objects. The plant also lets out rollers shock-absorbing various diameters which are established on tape the conveyor for mitigation of blows in places of loading. The shock-absorbing surface of such roller is formed by installation on a metal roller of rubber rings of various profile. Rollers deflektorny top for a channeled rolikoopora are recommended to be established on all route of the conveyor with a step 10-15 m, and also in places where on the party damage of edges of a tape can result from a tape descent. Rollers deflektorny lower for a flat tape are established on sections of a middle part of the conveyor with a step of 10-15 m, and also in those places where the intensive descent of a tape and damage of its edges is possible.

The term of production is 6-8 working days.
