An elliptical wave generator flexes a slim flex spline into a ring-type circular spline, engaging many teeth at once to deliver high reduction ratios in a compact space. The DSH-AH packs that gearing into a completely sealed unit with a hollow-type flex spline and an included crossed roller bearing, shipped assembled and lubricated.

Need 30% more torque from the same sealed hollow unit? DGH-AH is the heavy-load build. View DGH-AH Series →

Series tiers

The second letter of the type code picks the tier; the sealed hollow (AH) execution exists in all three.

  • S Standard (DSH-AH) — The base tier
  • G Heavy load (DGH-AH) — Higher torque load and life than standard
  • T Thin (DTH-AH) — Ultra-thin hollow structure

Customized executions

An optional final code marks a customized build.

  • M High tilting moment — Reinforced against moment loads
  • L Lightweight — Weight-reduced execution
  • S Surface treatment — Environmental protection
  • C Customized — Built to customer requirement

How buying works

Spec it in the configurator: drawings, 3D CAD, and a quote to follow.

HIWIN series are configured to your application, not bought off the shelf. Start from your loads and speeds if you are still choosing a size.
