Varvel worm gearbox - F RS 40 - Output shaft Ø18mm

The Varvel F RS40 Worm Gearbox: Compact and Reliable Power Transmission for Industry and Agriculture

Designed for demanding environments, the Varvel F RS40 worm gearbox stands out as a benchmark in mechanical power transmission. Versatile and robust, it integrates seamlessly into both industrial and agricultural applications, offering an optimal balance of performance, longevity, and ease of maintenance.

Manufactured in Italy, in the Emilia-Romagna region, this gearbox benefits from globally recognized expertise. It is particularly suitable for conveyors, mixers, transport systems, agricultural machinery, automated lines, labeling machines, and continuous operation equipment.

At Dymatec Industries, each gearbox is carefully selected and configured to ensure optimal compatibility with current industrial installations.

The G-version coupling ensures direct transmission and simplified maintenance

The F RS40 is equipped with a G-version motor-gearbox coupling, ensuring direct and efficient torque transmission. This design prevents motor shaft locking after long periods of use, thus simplifying maintenance operations and reducing maintenance costs.

Choose from 12 reduction ratios to precisely adapt your output speed

With an extensive range of 12 reduction ratios — 5, 7, 10, 15, 20, 28, 40, 49, 56, 70, 80 and 100 — the F RS40 allows precise adjustment of the output speed and torque according to the constraints of each application. The output speed is simply obtained by dividing the motor speed by the selected ratio.

Multiple mounting systems for flexible integration on all your equipment

The gearbox adapts to all mechanical configurations thanks to several mounting systems:

• Direct mounting on casing (PC or PA version)
• Fixing by output flange (types FL, FA or FB) with standardized bolt circles
• Installation on mounting feet
• Mounting with torque arm equipped with silent blocks to absorb vibrations and mechanical stresses

Hollow shaft Ø18 mm as standard, with adaptable output configurations

Delivered as standard with a Ø18 mm hollow shaft for compact mounting, the F RS40 can also be configured with:

• A single-sided solid output shaft (AS)
• A double-sided solid output shaft (AD)

The F RS40 is compatible with standardized IEC 56, 63, and 71 electric motors

The gearbox accepts motor input flanges to the following IEC standards:

These configurations ensure a precise mechanical connection and optimal torque transfer.

Numerous technical options to customize your F RS40 gearbox

The F RS40 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 increased precision
• VB: worm extension on the opposite side to the shaft
• VIT: Viton seals for aggressive environments
• ATEX: version suitable for explosive atmospheres

The Varvel F RS40 is interchangeable with major brands on the market

For a reliable replacement, check that the existing output shaft is indeed Ø18 mm. In case of modernization, providing the nameplate of the existing gearbox allows for quick identification of an equivalent or improved solution.

The F RS40 is generally interchangeable with gearboxes from the following manufacturers:

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