The most comprehensive range of idler rollers for light, medium, and heavy-duty applications.
Built to last in any industrial environment, available in steel, stainless steel, PVC, and aluminum.
Idler rollers are essential components for any roller conveyor system. Installed as passive components—that is, without their own motor—they allow packages, pallets, crates, and materials of all shapes and weights to move smoothly, reducing friction and ensuring a smooth, controlled flow.
NUOVA OMEC has been designing and manufacturing idler rollers for over thirty years for the manufacturing, logistics, ceramics, packaging, and many other industries. Each roller is made from high-quality materials and can be customized to meet specific requirements regarding load capacity, operating environment, and package type.
The correct selection of the idler roller depends on: the dimensions and weight of the package, the conveyor speed, environmental conditions (humidity, temperature, chemicals), the type of support surface, and the desired center-to-center distance between the rollers
Lightweight rollers for standard environments. PVC casing (standard anthracite gray) or steel. PVC end caps, technopolymer bearings with stainless steel balls. Load capacity up to 10 daN. Retractable shaft with spring (R version) for quick installation. Temperature range: −5°C to +80°C.
Lightweight PVC roller with PVC shaft and sleeve; low weight; economical. Load capacity up to 8 daN. Technopolymer bearings with steel balls. Ideal for light-duty packaging and sorting systems.
Light-to-medium-duty series made of galvanized steel. Wide range of shell diameters (32–76 mm) and shaft diameters (8–20 mm). High versatility for standard roller conveyors.
Light- to medium-duty roller with a pre-galvanized (Sendzimir) or stainless steel shell. Available with CNG grooves for round belt drives. Ideal for conveyors with curves.
The most versatile series in the OMEC lineup. Shaft diameter: 40–80 mm; shaft up to 30 mm in diameter. Available in idle, CNG-grooved, motorized, and clutch-equipped versions. Wide selection of finishes.
A reinforced version of the LGS with a thicker wall for higher loads. Particularly suitable for transporting industrial pallets and concentrated loads.
Medium-to-heavy-duty rollers. Shaft diameter: Ø25–40 mm; roller shell diameter: up to Ø133 mm. Large-size bearings for high load capacities. Ideal for logistics and automated sorting.
Unit Handling series specifically optimized for pallet transport. Casing with a shaft diameter of Ø30–40 mm, reinforced bearings. Load capacity ranging from 100 to 500 daN per roller.
Heavy-duty roller with a square tube (option Q) or round shell. 40 mm diameter shaft. Ideal for applications in harsh environments with high distributed loads.
Unit Handling Heavy-Duty Roller. Roller shell up to Ø159 mm, shaft up to Ø50 mm. Large-size bearing for loads up to over 1,000 daN. Standard for high-density automated warehouses.
Extra-Heavy Duty. Shaft diameter up to Ø60 mm. For the heaviest industrial loads: steel mills, foundries, and steel production facilities. Versions made of high-sliding-resistance hardened steel.
Nuova Omec idler rollers are a key component of any conveyor belt system. Designed to ensure smooth belt movement, they absorb vertical loads by distributing them evenly and minimizing friction.
Available in galvanized steel, stainless steel, and HDPE polyethylene, manufactured to tight tolerances across all diameters from 63 to 219 mm. Lengths can be customized to meet customer specifications.

For special applications (grip, antistatic properties, chemical resistance, food-grade use), steel rollers are available with interference-fit or vulcanized coatings:
Available axis configurations
Conveying packages, boxes, trays and pallets in automated warehouses, distribution centres and sorting lines. LGS, LP-UH and LMT-UH series.
Roller conveyors for handling green, dried and fired tiles. Stainless-steel and coated versions for environments with ceramic dust and high temperatures.
Heavy-duty rollers for belt conveyors operating in demanding environments, including quarries, mines, steelworks and cement plants. LEP and LMT-UH series for extra-heavy loads.
FDA-compliant stainless-steel versions with food-grade bearings and seals. Maximum hygiene and resistance to cleaning with water and aggressive detergents.
Selecting the right idler roller requires knowledge of certain key parameters. Our engineering department is available to assist with the design process, but here is a summary of the main criteria:
The idler roller rotates passively under the action of the shaft or gravity, without its own drive system. The motorized roller (or “motor”), on the other hand, incorporates an internal electric motor or a drive system (chain, belt) that actively moves the shaft along the conveyor.
Yes. NUOVA OMEC manufactures idler rollers with a shaft, end caps, and bearings made of AISI 304 stainless steel (designation IX1/IX). For food-contact applications, an FDA-compliant version is also available, featuring materials certified for food use, including seals and lubricants.
Yes, NUOVA OMEC manufactures custom rollers in non-standard lengths, in addition to the lengths listed in the catalog. Please contact the technical department for special lengths, specific diameters, or non-standard designs.
Yes, there is a specific line of conical rollers (idler and motorized) for creating 90° curves. The LGE-RS conical, LGS conical, and LGED (double roller) series allow for the construction of compact curves with inside radii of 800 mm and up.
