Higher Torque Coaxial Input Output Shafts Harmonic Drive Gearbox
The FSG-I series Strain wave gear employs an integrated cam-type wave generator. The camshaft bore dimensions can be customized to match customer-specific motor models. The input shaft directly interfaces with the wave generator’s inner bore via a keyed connection. This system is typically configured with the circular spline fixed at the base and the flexspline functioning as the output end.
Features
- The integrated cam design allows easier installation and offers multiple mounting configurations
- Higher torque output with optimized compact dimensions
- Precise rotation and positioning control for accurate motion
- Coaxial alignment between the input and output shafts
- Commonly used in robot arm joints or sealed rotary platforms requiring environmental protection

Shipping Policy
Fast Delivery! We ship via FedEx, UPS, DHL, and USPS because they are fast, reliable, and easily trackable. We process orders within 24 hours, and delivery may take 4-7 business days after that, depending on your location. We will email you the tracking number once your order is shipped.
Shipping Costs: For some industrial products, such as heavy wheels and CNC machines, shipping costs are calculated based on product weight, not quantity. To reduce shipping costs for orders with multiple items, please email us at sales@ozrobotics.com before placing your order. We show shipping rates on the product page under the SHIPPING tab. To view the shipping cost for your country, click 'Add to Cart' on the product page.
Return Policy
5 Hours: Mistakes happen when ordering, so you have 5 hours to request a refund for any reason, including if you don’t want to pay the tariff. However, Stripe will not refund you their processing fee if you cancel your order.
All Sales Are Final: After 5 hours, we cannot cancel your order or issue a refund because order cancellations require reverse tariff payments and multiple shipping fees, which are very costly and time-consuming. For technical issues, we will be happy to assist you in resolving problems and provide a replacement if you can prove that the product has a manufacturing defect.
Exchange Policy: We want you to be happy with your new purchase. However, once you have used the product, we cannot issue a refund. But we will offer an exchange for a product that has irreversible manufacturing defects or technical problems. If you purchased the wrong product, then you, as the customer, will be responsible for the re-shipping fees and tariffs. If the product you purchased is defective, email us at support@ozrobotics.com with photos or a video of the faulty parts so we can evaluate it before arranging for a replacement.
