Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Motors And Drives. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
The HST-20-100-III is a compact hollow-shaft harmonic drive gear reducer intended for automation equipment, robot arms, machinery, and other motion-control assemblies. Its HST-III construction uses a hollow flanged flexspline in a standard compact configuration.
The center opening is particularly useful for designs that need cables or other routing to pass through the reducer. The wave generator incorporates support bearings and uses a fully sealed structure to simplify installation.
The reducer has coaxial input and output, a cylindrical gear form, hardened tooth surfaces, and a single-stage arrangement. The stated model combines size 20 with a 100 reduction ratio. The documented design features include high torque capacity, high rigidity, compact construction, and smooth, low-noise operation.
Its proprietary HM tooth profile is described as increasing tooth . The documented service-life range is 10,000–15,000 hours, attributed to reduced wave-generator deformation and concentrated stress.
Before procurement, buyers should confirm the required output torque, input speed, output speed, duty cycle, operating conditions, mounting orientation, and connection method.
Motor drawings or complete motor parameters should be reviewed to verify the flange interface, shaft dimensions, input arrangement, and model suitability.
Buyers should also request dimensional drawings, tolerance data, backlash or positioning specifications, permissible loads, lubrication requirements, environmental limits, and the exact scope of any customization before approving the unit for a production machine.
