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-20-50-III is a compact hollow-shaft harmonic gear reducer for motion-control and power-transmission systems.
Its hollow flanged flexspline and open center are designed to accommodate cable routing through the reducer, which can simplify layouts where wiring, tubing, or other routed elements must pass along the motion axis.
The listed configuration uses a 50:1 reduction ratio, single-stage construction, cylindrical gearing, and coaxial input and output. The wave generator incorporates support bearings and uses a fully sealed structure intended to support straightforward installation.
Listed product characteristics include high torque capacity, high rigidity, compact construction, and smooth, low-noise operation. The reducer uses a hardened tooth surface and an HM tooth-profile design.
The stated service-life range is 10,000–15,000 hours;actual service life will depend on the selected configuration and operating conditions. This model is presented for motor, machinery, vehicle, motorcycle, and marine-related uses.
These broad application listings do not establish compatibility with a particular servo motor, machine, vehicle, or environment.
Before ordering, the buyer should confirm the required torque, input speed, output speed, duty cycle, mounting arrangement, connection method, motor flange, motor shaft dimensions, load conditions, and operating environment. A motor drawing with operating parameters can be used for configuration review.
Customization is listed as available, but its scope is not defined. Buyers should obtain an approved drawing and confirm whether the quotation covers a complete reducer or a component configuration.
Also verify the exact interfaces, allowable loads, backlash or positioning requirements, lubrication and maintenance needs, environmental protection, cable-routing clearance, and acceptance criteria.
Confirm the applicable warranty terms, inspection documentation, packaging, production schedule, and shipment arrangements in the purchase agreement.
