Varvel Worm Gearbox - F RS 40 - Output Shaft Ø20mm

Varvel FRS40 Ø20mm: The Worm Gear Solution for Industry and Agriculture

The Varvel FRS40 worm gear reducer is a technical benchmark combining compactness, robustness, and versatility. Designed to meet the demands of the industrial and agricultural sectors, it ensures reliable long-term operation while facilitating maintenance and upkeep.

A product of Italian expertise from the Emilia-Romagna region, this reducer successfully powers conveyors, mixers, transport systems, agricultural machinery, automated lines, and labeling machines, as well as any equipment requiring continuous operation.

Dymatec Industries offers a carefully selected range of FRS40 reducers, configured to ensure a perfect fit with your current industrial installations.

The G-version coupling prevents seizing and facilitates maintenance operations

The FRS40 includes a G-version motor-reducer coupling, ensuring efficient and lossless torque transfer. This system prevents the motor shaft from locking in case of prolonged shutdown, thus reducing downtime and maintenance costs.

Precisely fine-tune your output speed with the 12 available reduction ratios

The FRS40 is available in 12 reduction ratios: 5, 7, 10, 15, 20, 28, 40, 49, 56, 70, 80, and 100. This wide range allows for precise definition of the output speed and the necessary torque for each application. The calculation is simple: motor speed ÷ reduction ratio = output speed.

Varied mounting solutions for quick and secure installation

The FRS40 adapts to all mounting constraints thanks to several available configurations:

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

A standard Ø20 mm hollow shaft, with custom output configurations

The FRS40 comes standard with a Ø20 mm hollow shaft  for direct and compact installation. Alternative configurations are available as needed:

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

Extended compatibility with IEC 56, 63, and 71 standardized motors

The reducer accepts motor input flanges compliant with the following IEC standards:

These combinations guarantee optimal torque transmission and precise and secure installation.

Adapt your FRS40 to your needs with a wide range of technical options

The FRS40 can be configured according to the specific requirements of each application:

• AD: double output shaft
• AS: single output shaft
• ASC: protection cover for hollow shaft
• TLI: internal torque limiter
• TLE: adjustable external torque limiter
• GRM: low backlash version for precision applications
• VB: worm extension on the opposite side of the shaft
• VIT: Viton seals for aggressive environments
• ATEX: certified version for potentially explosive atmospheres

The Varvel FRS40: A direct replacement for major market reducer brands

To ensure a reliable replacement, verify that the existing output shaft is indeed Ø20 mm. In case of renovation, please provide the nameplate of your current equipment to quickly identify an equivalent or technically superior solution.

The FRS40 is interchangeable with reducers from the following manufacturers:

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

Our technical office is at your service to guide you towards the most suitable solution for your needs and ensure a rapid return to production, without modification of your existing infrastructure.
