Varvel Worm Gearbox - F RS 110 - Output shaft Ø42mm

Varvel FRS110 Ø42mm Reducer: Performance and Robustness for Your Industrial and Agricultural Transmissions

Designed for the most demanding production environments, the Varvel FRS110 worm gear reducer combines mechanical robustness, compact design, and adaptability. Whether for industrial or agricultural applications, this reducer ensures reliable, precise, and low-maintenance transmission, even under intensive operating conditions.

Originating from Italy's Emilia-Romagna region, globally renowned for its transmission mechanics expertise, the FRS110 is successfully integrated into equipment such as conveyors, mixers, transport systems, agricultural machinery, automated lines, and labeling machines—especially in installations operating continuously for extended periods.

At Dymatec Industries, each FRS110 unit undergoes thorough quality verification and tailored parameter setting to ensure optimal integration into your existing production lines.

FRS110 Ø42mm: Which Sectors and Applications?

Its ability to deliver significant torque at low speeds and its installation flexibility make the FRS110 a reference transmission component in many fields:

• Conveyors and conveyor belts: transport of parts, packages, or bulk materials on production lines
• Mixers and agitators: homogenization of food, chemical, or pharmaceutical products
• Screw conveyors and dosing systems: controlled distribution of raw materials in food processing and plastics
• Agricultural machinery: spreaders, seeders, irrigation systems, and harvesting equipment
• Gates and lifting devices: automation of barriers, industrial valves, and hatches
• Pumps and compressors: low-speed drive for viscous or charged fluids
• Packaging and labeling lines: precise regulation of rates on packaging lines
• Handling equipment: lifting tables, motorized trolleys, and automated transfers

Its reduced noise level and small footprint—two characteristics inherent to worm gear transmissions—make it a choice solution in environments where discretion, compactness, and durability are essential.

The G Version Coupling: Motor Shaft Protection and Increased Longevity

The FRS110 is equipped with a G version motor-reducer coupling, ensuring direct, stable, and energy-loss-free torque transfer. This system prevents motor shaft seizure during prolonged shutdowns, limits unplanned interventions, and helps sustainably reduce your maintenance costs.

12 Reduction Ratios for Precise Transmission Adjustment

The FRS110 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 depending on each application. The calculation is simple: motor speed ÷ reduction ratio = output speed.

Four Mounting Modes to Adapt to All Your Equipment

The FRS110 offers several mounting configurations to meet all installation constraints:

• Housing mount (PC version)
• FL or FB output flange with standardized bolt circles
• Mounting on mounting feet
• Torque arm with silent block to absorb vibrations and dynamic forces
• Hollow shaft Ø42mm supplied as standard, with customizable output options

The standard Ø42 mm hollow shaft allows for a direct, precise, and backlash-free connection to your machine. For specific configurations, two alternatives are offered:

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

Native Compatibility with Standardized IEC 90, 100, 112, and 132 Motorizations

The FRS110 accepts motor flanges conforming to the following IEC standards:

These combinations ensure a solid and precise mechanical link between motor and reducer for uncompromised power transfer.

Multiple Technical Options to Customize Your Varvel FRS110 Reducer

The FRS110 is available in several variants to adapt to the specific requirements of each installation:

• 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 high-precision applications
• VB: worm extension opposite the shaft
• VIT: Viton seals for chemically aggressive environments
• ATEX: certified version for explosive atmospheres

The Varvel FRS110 Ø42mm: A Direct Substitute for Major Brand Reducers

For a safe replacement, ensure that the existing output shaft is indeed Ø42 mm. For modernization or renovation projects, please provide the nameplate of your current reducer to quickly identify the technically equivalent or superior solution.

The FRS110 is interchangeable with reducers from the following manufacturers:

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

Our team of mechanical transmission specialists is available to assist you in choosing the appropriate reducer and ensuring a quick return to production without modifying your infrastructure.
