Monobloc steel - Import export

Clamped or monobloc steel rollers mounted on pre-lubricated and protected radial ball bearings.The externally threaded axle protrudes from one end of the tube only. They are vertically mounted, with a guiding and sliding function, in gravity or motor-driven conveyors.The technical characteristics of Series 6 rollers are those of the relative base rollers.

Steel rollers with the jacket consisting of tube and bearing mounting head rigidly coupled by welding.Monobloc steel rollers are used in conveyors with medium, heavy or very heavy loads. Depending on their application, the rollers have specific shapes for connection to the structure. This need is particularly noticeable in the production of gravity and motor-driven conveyors.For the correct installation of steel idlers, refer to the “Fixing rollers to structures” section on page 11.For the correct installation of motor-driven rollers, refer to the “Fixing rollers to structures” section on page 68. The diagrams and Table 60 show the shapes of the ends of the axles envisaged in TECNORULLI production’s “Monobloc steel rollers” programme.On request, other forms of connections and rollers with hubs can be considered.

Steel rollers with jacket consisting of tube and bearing mounting head rigidly coupled by welding. They are mounted on pre-lubricated angular or radial ball bearings and protected with double labyrinth, triple labyrinth dust seals with additional watertight protection. Monobloc steel rollers are used in belt conveyors with medium, heavy or very heavy loads. The diagrams and tables on page 42 show the dimensional characteristics and maximum loads.Operating temperature:-10 ÷ +90 [°C].

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.

Due to the structural characteristics of the materials of which they are made, these rollers are used for motor-driven conveyor in combined systems of handling and stockpiling of light, medium-heavy and heavy packages in normal, dusty, corrosive, and also humid and warm environments.They are made of clamped or monobloc base rollers with steel tube, crown and simple double steel pinions, aligned on the tube or at one end of the jacket.

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.

Due to the structural characteristics of the materials of which they are made, these rollers are used in belt conveyors in handling systems of bulk materials, including sharp and abrasive, mixed size, large and heavy materials, in normal, dusty and aggressive environments. As upper rollers, their field of application is specifically in the loading areas of conveyors to protect the rubber matting from the dynamic action of falling materials. They consist of monobloc base rollers with steel tube and special anti-abrasive rubber rings pressure-aligned on the jacket.

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.

DESCRIPTION Circular electromagnet, heavy-duty and service cycle of 75% ED. Built of copper or aluminum coil, according to capacity requirements. Among the construction characteristics, it is worth mentioning: ·Heavy-duty monobloc carcass of moulded steel with high strength ribs and high mechanical strength ·Two protection shields of non magnetic steel ·Heavy-duty connection box ·Isolation class H ·Lugs with steel bushes to avoid wear ·Suspension chain of three ways of high strength alloy steel with a traditional eye bolt APPLICATIONS Aimed at meeting any handling need for ferrous materials: from small scrap yards to heavy duty steel industry. Due to their low weight and high mechanical strength they are ideal for hydraulic boom cranes in high performance applications. Adequate for underwater works following prior minimum service.
