Varvel Worm Gearbox - F RS 130 - Output shaft Ø48mm

Ref: F RS 130 Ø48

Combining robustness and reliability, the Varvel FRS130 worm gearbox, with its circular cast iron casing, ensures precise and smooth speed reduction, while offering an output torque of up to 1,680 Nm. Thanks to its compact design, it easily integrates into conveyor systems, automated lines, and all industrial equipment requiring efficient transmission in a confined space.

Its hollow shaft Ø48 mmallows for direct mounting on the machine, without an intermediate coupling element, guaranteeing a rigid, reliable, and backlash-freeconnection, immediately operational.

The FRS130 is available in several mounting configurations depending on installation constraints, including mounting on a PC casing, a FL flange, mounting with mounting feet, as well as a torque arm with silent-blocdesigned to reduce vibrations and absorb mechanical stress.

Compatible with standardized three-phase IEC 100, IEC 112, and IEC 132 motors, it covers a wide range of powers and motor configurations, thus facilitating its integration into numerous industrial environments.

In case of replacement, providing the nameplate of the existing equipmentallows for quick identification of an equivalent or more powerfulsolution, perfectly suited to your installation.

Varvel FRS130 Ø48 mm Reducer: A Reliable and High-Performance Solution for Your Transmission Systems

Designed to meet the demands of the most challenging industrial and agricultural environments, the Varvel FRS130 worm gear reducer combines robustness, compactness, and versatility. It ensures efficient, precise, and durable power transmission while minimizing maintenance needs, even with intensive use.

Manufactured in Emilia-Romagna, an Italian region renowned for its expertise in industrial mechanics, the FRS130 successfully powers numerous installations such as conveyors, mixers, handling systems, agricultural machinery, automated lines, and labeling equipment. It is particularly suited for applications operating continuously for long periods.

At Dymatec Industries, each FRS130 reducer undergoes rigorous quality control and is configured to your specific needs to ensure optimal integration into your existing equipment.

In Which Sectors Can the FRS130 Ø48 mm Be Used?

Thanks to its ability to deliver high torque at low speed and its numerous mounting options, the FRS130 finds its place in many fields of activity:

  • Conveyors and conveyor belts for moving parts, packages, or bulk products

  • Mixers and agitators for the food, chemical, or pharmaceutical industries

  • Dosing screws and feeding systems requiring precise flow control

  • Agricultural machinery such as seeders, spreaders, irrigation or harvesting equipment

  • Motorized gates, industrial valves, and automated lifting devices

  • Pumps and compressors operating at low rotational speed

  • Packaging, wrapping, and labeling lines requiring a controlled pace

  • Handling equipment such as lifting tables, transfer conveyors, or motorized trolleys

Its silent operation and reduced footprint, characteristic of worm gear reducers, make it a particularly popular solution when compactness, discretion, and longevity are essential criteria.

Coupling Version G: Enhanced Motor Protection

The FRS130 integrates a type G motor-reducer coupling, enabling stable and efficient torque transmission. This design reduces the risk of motor shaft seizure after long periods of inactivity and helps minimize maintenance operations while extending the lifespan of the entire transmission unit.

Twelve Reduction Ratios to Meet Every Need

Available with 12 reduction ratios (5 to 100), the FRS130 allows for precise adaptation of the output speed and transmitted torque to the specific application.

The calculation remains simple:

Motor speed ÷ reduction ratio = output speed

Several Mounting Configurations Available

To adapt to installation constraints, the FRS130 can be supplied in several versions:

  • Casing mounting (PC version)

  • FL output flange

  • Foot mounting

  • Torque arm with silent block to absorb vibrations and dynamic forces

Ø48 mm Hollow Shaft as Standard with Output Options

The reducer is originally equipped with a Ø48 mm hollow shaft, allowing for direct and precise coupling with the driven machine.

Available options:

  • AS: single solid output shaft

  • AD: double solid output shaft

Compatibility with Standard IEC Motors

The FRS130 is compatible with standard IEC motors:

Motor Flange Compatible Motor Shaft
IEC 100 B5 Ø250 Ø28 x 60 mm
IEC 112 B5 Ø250 Ø28 x 60 mm
IEC 132 B5 Ø300 / IEC 132 B14 Ø200 Ø38 x 80 mm

This compatibility ensures a reliable mechanical connection and optimal power transmission.

Customization Options

The FRS130 can be equipped with numerous technical options:

  • AD: double output shaft

  • AS: single output shaft

  • ASC: protective cover for hollow shaft

  • TLI: internal torque limiter

  • TLE: adjustable external torque limiter

  • GRM: low backlash version for high precision

  • VB: worm extension

  • VIT: Viton seals for aggressive chemical environments

  • ATEX: version for explosive atmospheres

A Reliable Alternative to Major Brands

For replacement, it is essential to check for a Ø48 mm output shaft. In case of renovation, the nameplate allows for the identification of an equivalent solution.

The FRS130 can replace numerous manufacturers:

  • Motovario

  • Bonfiglioli

  • SITI

  • STM

  • SEW-Eurodrive (depending on configuration)

  • Rossi

Dymatec Industries specialists will assist you in ensuring a quick return to production without major modification to your installation.
