Varvel F RD02 Coaxial Gearbox – Output Shaft Ø17 x 35 mm

What is the Varvel FRD02 coaxial geared motor?

The Varvel FRD02 is a coaxial helical geared motor designed to reduce the speed of an electric motor while increasing the output torque. Compact and robust, it is intended for industrial applications such as conveyors, handling systems, automated machines, and process equipment.

Its reliable design ensures quiet and durable operation in continuous service.

How does the Varvel FRD02 work?

The FRD02 relies on a helical gear system that reduces rotational speed while increasing the transmitted output torque. This technology ensures progressive transmission, limiting vibrations and improving the lifespan of the entire geared motor.

The geared motor is designed to be directly coupled to an electric motor via a standardized input, ensuring simple and efficient integration.

What are the motor compatibilities of the FRD02?

The FRD02 is compatible with standardized IEC electric motors:

• IEC 56
• IEC 63
• IEC 71
• IEC 80

Coupling is done via a B5 or B14 motor flange, depending on the configuration, with integrated elastic coupling.

What are the dimensions of the B5 and B14 motor flanges?

The standardized dimensions are as follows:

• IEC 56
  • B5: Ø120 mm
  • B14: Ø80 mm
• IEC 63
  • B5: Ø140 mm
  • B14: Ø90 mm
• IEC 71
  • B5: Ø160 mm
  • B14: Ø105 mm
• IEC 80
  • B5: not used on this range
  • B14: Ø120 mm

What reduction ratios are available?

The FRD02 is available with the following ratios:

2.25 / 2.5 / 2.80 / 3.15 / 3.55 / 4 / 4.5 / 5 / 5.6 / 6.3 / 7.1 / 8 / 9 / 10 / 11.2 / 12.5 / 16 / 20 / 25 / 31.5 / 40 / 50

This range allows for precise adaptation of the output speed to each industrial application.

What is the output shaft type of the FRD02?

The Varvel FRD02 geared motor is equipped with a Ø17 mm solid output shaft, suitable for light to medium industrial applications. It allows for the mounting of various transmission elements such as pulleys, sprockets, or flexible couplings.

What mounting options are available for the FRD02?

The Varvel FRD02 can be mounted in two main ways depending on the installation:

• Mounting with foot brackets (B3)
• Mounting with a front flange

The flange version allows for direct mounting on the front face of the machine or frame, while the foot-mounted version offers classic mounting on a support. This dual possibility ensures great integration flexibility, both for new installations and replacements.

What are the equivalences of the Varvel FRD02?

The FRD02 from Varvel is compatible with many coaxial geared motors on the market, including those from SEW-Eurodrive, Motovario, Bonfiglioli, Leroy-Somer, and STM, subject to checking interfaces and ratios.

It constitutes a reliable replacement solution thanks to its standardized dimensions and its Ø17 mm output shaft.

Technical Conclusion

The FRD02 is a compact and versatile geared motor, suitable for light industrial applications. Its IEC B5/B14 compatibility, ratios up to 50, Ø17 mm shaft, and two mounting modes make it a simple-to-integrate and reliable solution in operation.
