Varvel F RD32 Coaxial Gear Reducer – Output Shaft Ø30 x 60 mm

Ref: F RD32 Ø30

The Varvel FRD32 reduceris part of the Varvel helical coaxial series, from the Italianmanufacturer specializing in industrial power transmission. Designed to reduce the rotational speed of an electric motor while delivering higher output torque, it meets the demands of the most challenging production environments. This version stands out with its Ø30x60mm solid shaft, whose reinforced section provides increased transmission capacity, ideal for high-torque applications requiring direct connection of pulleys, sprockets, or elastic couplings. The 115mm shaft heightensures easy interchangeability with existing equipment.

With its 23 reduction ratios from 2.25 to 63, the Varvel FRD32 reduceris a solution adaptable to a wide variety of industrial needs — conveyors, production equipment, automated lines — offering precise adjustment of output speed for each configuration. The maximum output torque of 420 Nmpositions it as a reliable choice for high mechanical stress applications.

Motor connection is made via a standardized B5 or B14 flange, compatible with IEC 71, 80, 90, 100, and 112 frames, ensuring direct implementation with market motors without any mechanical adaptation. An integrated elastic couplingprotects the entire transmission chain against starting shocks and unforeseen overloads.

The Varvel FRD32 reducercan be mounted either on B3 feetfor installation on a chassis or frame, or by output flange— available in Ø160mm, Ø200mm, or Ø250mm— for compact mounting directly on the machine.

Why choose the Varvel F RD32 Reducer — Ø30mm Output Shaft?

The Varvel brand: a global leader in power transmission

Varvel is an internationally renowned Italian manufacturer, specializing for over 60 years in the design and production of mechanical reducers, gearmotors and transmission components. Recognized for the impeccable quality of its products, the precision of its manufacturing, and the reliability of its solutions in the field, Varvel has established itself as a key player among industrialists worldwide. Choosing a Varvel reducer means opting for equipment designed to last, engineered to perform, and manufactured according to the most demanding standards of the mechanical industry.

The RD series is one of Varvel's flagship ranges. These are in-line helical gear coaxial reducers, known for their high mechanical efficiency, modular structure, and great installation versatility. The size 32, represented by the F RD32 model, is a compact square-shaped solution, particularly appreciated for its robustness and its ability to integrate into confined spaces while delivering high performance.

Technical specifications

The Varvel F RD32 reducer is a solution with high-precision helical gears guaranteeing smooth, silent, and highly efficient transmission, while limiting vibrations and premature wear of components. Its main features are:

  • Type : In-line helical gear coaxial reducer
  • Brand / Series : Varvel — RD Series, size 32
  • Output shaft : solid, keyed, Ø30mm
  • Shaft height : 115mm
  • Maximum output torque : 420 Nm
  • Number of available reduction ratios : 23 ratios (from 2.25 to 63)
  • Housing : square shape, compact construction
  • Lubrication : oil bath, reduced maintenance
  • ATEX version : available on request for explosive environments

Motor compatibility and IEC input flanges

The F RD32 model is designed for the direct mounting of standardized IEC electric motors. The letter F in its designation indicates the presence of an IEC motor input flange, allowing direct connection without complex couplings. This reducer is compatible with motor sizes IEC 71, 80, 90, 100, and 112, in both B5 and B14 flanges.

For IEC 71 size, the B5 flange has a diameter of 160mm and the B14 flange a diameter of 120mm. For IEC 80 size, the B5 flange is 200mm in diameter and the B14 flange is 120mm. For IEC 90 size, the B5 flange reaches 200mm and the B14 flange 140mm. For IEC 100 and IEC 112 sizes, both share the same dimensions: the B5 flange is 250mm and the B14 flange is 160mm in diameter. This broad compatibility ensures direct and simplified integration with the vast majority of standard electric motors available on the market.

Mounting and installation

The Varvel F RD32 reducer offers two distinct mounting options, allowing adaptation to the specific constraints of each installation. It can be mounted with feet, a standard solution for mounting on a chassis or machine frame. It can also be fixed with an output flange, available in three diameters: Ø160mm, Ø200mm, or Ø250mm, depending on assembly requirements. The standardized shaft height of 115mm facilitates interchangeability and simplifies integration into existing configurations.

23 available reduction ratios

The F RD32 reducer is available in 23 reduction ratios covering an extended range from 2.25 to 63. The available ratios are: 2.25 — 2.82 — 3.55 — 4.46 — 5.18 — 5.61 — 7.09 — 7.72 — 8.92 — 10.06 — 11.22 — 12.37 — 14.17 — 15.44 — 17.84 — 20.12 — 22.44 — 25.26 — 28.34 — 31.76 — 35.68 — 44.68 — 63.00. This range of choices allows for precise adaptation of output speed and transmitted torque to the requirements of each application, whether for slow movements with high torque or moderate-speed transmissions.

What applications can a FRD32 coaxial reducer be found in?

Thanks to its compactness, robustness, and versatile configurations, the Varvel F RD32 reducer is used in numerous industrial sectors. It is particularly suitable for food processing applications such as conveyors, mixers, and packaging lines. It also meets the needs of the agricultural sector, machine tools, building and construction, as well as the energy industries, particularly in solar tracking systems and wind turbines. More broadly, it integrates into any automation, robotics, or industrial handling system requiring reliable and precise transmission.

Key strengths of the Varvel F RD32 reducer

This reducer embodies the excellence of Varvel manufacturing: maximum torque of 420 Nm, 23 reduction ratios between 2.25 and 63, full IEC compatibility from size 71 to 112 in B5 and B14, dual mounting options with feet or with an output flange in Ø160, Ø200, or Ø250mm, and standardized shaft height of 115mm. Its modular structure reduces management and maintenance costs, while its helical gear design ensures silent operation and optimal efficiency over time. An ATEX version is also available for explosive atmosphere environments.
