Varvel Worm Gearbox - F RS 60 - Ø25mm Output Shaft

Varvel FRS60 Ø25mm worm gear reducer: reliability and power for your industrial and agricultural transmissions

Developed for the most demanding environments, the Varvel FRS60 worm gear reducer stands out for its mechanical robustness, compact size, and high flexibility of use. Whether for industrial or agricultural applications, it offers efficient and durable transmission, while minimizing daily maintenance requirements.

Originating from the renowned expertise of Italy's Emilia-Romagna region, the FRS60 integrates perfectly into conveyors, mixers, transport systems, agricultural machinery, automated lines, and labeling machines, as well as any equipment requiring intensive and continuous operation.

At Dymatec Industries, each FRS60 reducer undergoes rigorous inspection and precise parameter setting to guarantee perfect suitability for your production facilities.

What are the applications for the Varvel FRS60 worm gear reducer?

Its ability to generate high torque at low rotation speeds and its versatility of installation make the FRS60 an essential transmission solution in many sectors. It is typically found on:

• Conveyors and belt conveyors: conveying parts, packages, or bulk materials in industrial environments
• Mixers and agitators: stirring and homogenization of food, chemical, or pharmaceutical products
• Screw conveyors and dosing systems: precise distribution of raw materials in the food and plastics industries
• Agricultural machinery: spreaders, seeders, irrigation equipment, and harvesting machinery
• Gates and lifting systems: control of automatic barriers, industrial valves, and hatches
• Pumps and compressors: slow drive for viscous or heavily laden fluids
• Packaging and labeling lines: precise regulation of speeds on packaging lines
• Handling equipment: lifting tables, motorized trolleys, and transfer systems

Its low noise level and reduced footprint — two characteristic advantages of worm gear transmissions — make it a preferred choice in environments where quiet operation, compactness, and reliability are essential.

The G version ensures optimal torque transfer and extends the reducer's lifespan

The FRS60 features a motor-reducer coupling in G version that guarantees direct, precise, and energy-loss-free torque transmission. This device eliminates the risk of motor shaft seizure during extended shutdown periods, reduces the frequency of maintenance interventions, and helps to permanently reduce your operating costs.

Precisely adjust your transmission with the 12 available reduction ratios

The FRS60 covers a range of 12 reduction ratios: 5, 7, 10, 15, 20, 28, 40, 49, 56, 70, 80, and 100, offering great flexibility to adjust the output speed and transmitted torque to the specific constraints of each installation. To determine the output speed: motor speed ÷ reduction ratio = output speed.

Four mounting configurations to adapt to all your installation constraints

The FRS60 offers great freedom of installation thanks to its different mounting options:

• Frame mounting (PC or PA version)
• FL, FA, or FB output flange with standardized bolt circles
• Installation on mounting feet
• Torque arm with silent block to absorb vibrations and dynamic forces

Ø25 mm hollow shaft as standard, with customizable output configurations

The FRS60 comes standard with a Ø25 mm hollow shaft ensuring a direct, compact, and backlash-free connection to your machine. For specific needs, two output options are also available:

• Single solid output shaft (AS)
• Double solid output shaft (AD)

Full compatibility with IEC 71, 80, and 90 standard electric motors

The FRS60 connects to motor input flanges with the following IEC standards:

These combinations ensure a rigorous mechanical link between motor and reducer for uncompromising power transfer.

Numerous technical options to customize your FRS60 reducer

The FRS60 is available in multiple configurations to meet the specific requirements of each application:

• 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 applications
• VB: screw extension on the side opposite the shaft
• VIT: Viton seals for chemically aggressive environments
• ATEX: certified version for potentially explosive atmospheres

The Varvel FRS60: interchangeable with major industrial reducer brands

To ensure a risk-free replacement, make sure that the existing output shaft is indeed Ø25 mm. For equipment renovation or modernization, provide the nameplate of your current reducer to quickly determine the equivalent or technically superior solution.

The FRS60 is compatible for replacement with the following manufacturers:

• Motovario
• Bonfiglioli
• SITI
• STM
• SEW-Eurodrive (depending on configurations)
• Rossi

Our specialized technical team is at your disposal to guide you towards the most suitable reducer for your needs and ensure immediate resumption of activity, without intervention on your existing infrastructure.
