Overview

Radicon Series C right-angle helical-worm gearmotors and reducers add a helical input stage to worm gearing, for higher efficiency and a wider ratio range than a plain worm in a compact, quiet unit. Series C shares components with Series M, and like the rest of the family it is built from modular kits, so we assemble the size, ratio, input and output you need in our own shop.

Series C is also the current replacement for older Radicon helical-worm designs, built to the same footprints most plants already run.

Why Series C

  • Accepts standard NEMA and IEC motors, or a keyed input shaft
  • Hollow or plug-in output shafts and bolt-on flanges for flexible mounting
  • Higher efficiency than a plain worm, thanks to the helical input stage
  • Quiet, compact right-angle drive with high load capacity
  • Wide ratio range: 8:1 to 250:1, and up to 14,000:1 in combined units

Frequently Asked Questions

Helical-worm or plain worm: which should I choose?

A helical-worm unit such as Series C runs more efficiently than a plain worm and covers a wider ratio range, which lowers running costs on continuous duty. A plain worm can still suit light, intermittent or very low-speed drives. We can help compare the two for your application.

Can Series C replace an older Radicon helical-worm unit?

In most cases, yes. Series C is the current replacement for earlier Radicon helical-worm designs. Send us the nameplate and photos and we will confirm the fit.

Is a hollow output available?

Yes. Series C is offered with a hollow output or a plug-in solid output shaft, and with bolt-on flanges.

Does Gordon Russell build Series C locally?

Yes. We are a Radicon build centre for Series M, C, F and K and assemble Series C units to order in our shop from stocked kits.
