It ensures efficient, precise, and durable power transmission while minimizing maintenance needs, even with intensive use.

Manufactured in Emilia-Romagna, an Italian region renowned for its expertise in industrial mechanics, the FRS130 successfully powers numerous installations such as conveyors, mixers, handling systems, agricultural machinery, automated lines, and labeling equipment. It is particularly suited for applications operating continuously for long periods.

At Dymatec Industries, each FRS130 reducer undergoes rigorous quality control and is configured to your specific needs to ensure optimal integration into your existing equipment.

In Which Sectors Can the FRS130 Ø48 mm Be Used?

Thanks to its ability to deliver high torque at low speed and its numerous mounting options, the FRS130 finds its place in many fields of activity:

• Conveyors and conveyor belts for moving parts, packages, or bulk products

• Mixers and agitators for the food, chemical, or pharmaceutical industries

• Dosing screws and feeding systems requiring precise flow control

• Agricultural machinery such as seeders, spreaders, irrigation or harvesting equipment

• Motorized gates, industrial valves, and automated lifting devices

• Pumps and compressors operating at low rotational speed

• Packaging, wrapping, and labeling lines requiring a controlled pace

• Handling equipment such as lifting tables, transfer conveyors, or motorized trolleys

Its silent operation and reduced footprint, characteristic of worm gear reducers, make it a particularly popular solution when compactness, discretion, and longevity are essential criteria.

Coupling Version G: Enhanced Motor Protection

The FRS130 integrates a type G motor-reducer coupling, enabling stable and efficient torque transmission. This design reduces the risk of motor shaft seizure after long periods of inactivity and helps minimize maintenance operations while extending the lifespan of the entire transmission unit.

Twelve Reduction Ratios to Meet Every Need

Available with 12 reduction ratios (5 to 100), the FRS130 allows for precise adaptation of the output speed and transmitted torque to the specific application.

The calculation remains simple:

Motor speed ÷ reduction ratio = output speed

Several Mounting Configurations Available

To adapt to installation constraints, the FRS130 can be supplied in several versions:

• Casing mounting (PC version)

• FL output flange

• Foot mounting

• Torque arm with silent block to absorb vibrations and dynamic forces

Ø48 mm Hollow Shaft as Standard with Output Options

The reducer is originally equipped with a Ø48 mm hollow shaft, allowing for direct and precise coupling with the driven machine.

Available options:

• AS: single solid output shaft

• AD: double solid output shaft

Compatibility with Standard IEC Motors

The FRS130 is compatible with standard IEC motors:

This compatibility ensures a reliable mechanical connection and optimal power transmission.

Customization Options

The FRS130 can be equipped with numerous technical options:

• AD: double output shaft

• AS: single output shaft

• ASC: protective cover for hollow shaft

• TLI: internal torque limiter

• TLE: adjustable external torque limiter
