Clamped Steel Rollers

Steel clamped or monobloc rollers mounted on pre-lubricated and protected radial ball bearings.The externally threaded shaft protrudes from only one end of the tube.In belt conveyors, they are vertically mounted in pairs at the edges of the rubber matting, with the function of restricting any lateral slipping. They are installed on self-centring stations with the same function.The technical characteristics of Series 6 rollers are those of the relative base rollers.Other finishes, see page 30.

They consist of two steel clamped or monobloc rollers mounted on a single “V”-folded shaft. They have the upper bearing mounting heads with hermetic closure and the lower ones, with protruding shaft, with labyrinth dust protection. The shaft is locked in the housing of the central bracket.The latter, with a base plate fitted with mounting holes, is made of cold-formed steel sheet.They are used in concave belt conveyors that operate, even in bad environmental conditions, at medium-high speed, with medium loads and sizes.

Due to the characteristics of the materials of which they are made, these rollers are used in conveyors operating in highly corrosive environmental conditions.With a state-of-the-art manufacture, they possess the requisites of the specifications for steel rollers on page 4. Operating temperature: 10 ÷ +50 [°C].

Garland roller sets are used in belt conveyors that have to handle blunt, bulky, heavy materials. The increased containment capacity of the roller basin facilitates higher speed of transport than those of traditional stations. For upper stations in current use installations, garland sets with 3 and 5 steel or rubberised impact rollers are mounted; for lower stations, garland sets with 2 steel rollers or with scraping rubber rings are mounted. The flexibility of garland sets enables their adaptation to the material to be transported, facilitates transportation, reduces impacts on the rollers, and limits any lateral slipping of the rubber matting. The diagrams and Table 90 show the shapes of mountings of garland sets envisaged in TECNORULLI’s production programme. Other shapes may be considered on request.
