Varvel worm gearbox - F RS 40 - Output shaft Ø19mm

Varvel FRS40 gearbox: the versatile worm gearbox for your industrial and agricultural applications

Known for its reliability and robustness, the Varvel F RS40 worm gearbox meets the highest requirements for mechanical transmission. Suitable for both industrial and agricultural environments, it combines high performance, durability, and easy maintenance for optimal productivity.

Produced with Italian expertise from the Emilia-Romagna region, this gearbox is perfectly suited for conveyors, mixers, transport systems, agricultural machinery, automated lines, labeling machines, and any equipment operating continuously.

At Dymatec Industries, each unit is rigorously selected and configured to ensure optimal integration into modern industrial installations.

The G version simplifies assembly and extends the lifespan of your installation

The F RS40 incorporates a G-version motor-gearbox coupling that ensures direct and efficient torque transfer. This technology prevents motor shaft seizure during prolonged shutdowns, facilitating maintenance operations and significantly reducing maintenance costs.

12 reduction ratios available for precise adjustment of your output speed

The F RS40 offers 12 reduction ratios: 5, 7, 10, 15, 20, 28, 40, 49, 56, 70, 80, and 100, allowing fine adjustment of the output speed and transmitted torque according to the needs of each installation. To calculate the output speed, simply divide the motor speed by the chosen ratio.

A wide range of mounting systems to adapt to all your configurations

The F RS40 is easily installed thanks to various mounting solutions:

• Direct mounting on casing (PC or PA version)
• Output flange (FL, FA or FB types) with standardized bolt circles
• Mounting on mounting feet
• Installation with torque arm and silent block to dampen vibrations and mechanical stresses

The Ø19 mm hollow shaft as standard for direct mounting, with customizable output options

The F RS40 comes standard with a Ø19 mm hollow shaft ensuring direct and compact mounting. It can also be equipped as needed with:

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

Full compatibility with standardized IEC 56, 63 and 71 electric motors

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

These configurations ensure a precise mechanical connection between motor and gearbox for lossless torque transfer.

Customize your F RS40 gearbox with its many technical options

The F RS40 offers a wide range of options 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: reduced backlash version for greater precision
• VB: worm extension on the side opposite the shaft
• VIT: Viton seals for aggressive environments
• ATEX: certified version for explosive atmospheres

The F RS40 easily replaces gearboxes from major industry brands

For a risk-free replacement, make sure the existing output shaft is indeed Ø19 mm. In case of equipment renovation, provide the nameplate of the existing gearbox to quickly identify an equivalent or more powerful solution.

The F RS40 is compatible for replacement with the following brands:

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