Monobloc 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.

Steel rollers with jacket consisting of tube and bearing mounting head rigidly coupled by pressure. They are mounted on pre-lubricated angular or radial ball bearings protected with double-labyrinth dust seals. Clamped steel rollers are used in belt conveyors with limited or medium-heavy loads. The diagrams and tables on page 34 show the dimensional characteristics and maximum loads. Operating temperature:-10 ÷ +90 [°C].

Due to the structural characteristics of the materials of which they are made, these rollers are used in belt conveyors in handling systems for bulk, humid or sticky materials, in normal, aggressive environments; operating temperature also low. As lower rollers (return) because they prevent the accumulation of material carried by the band, the field of application is specifically on the steel tubes; they thus favour linear and jolt-free running of the rubber matting. They consist of clamped or monobloc base rollers with steel tube and special anti-abrasive rubber rings pressure-aligned on the jacket.
