Harmonic Drive® precision component sets are the core motion control mechanisms. These zero backlash products offer the widest design flexibility. Products can be selected which offer the optimum dimension and performance based on the available volume within the customer-designed housing. High Torque, Ultra Flat, and Hollow Shaft Options are available. These high accuracy gearing components are often used as the core building block for custom high performance servo actuators and motion control mechanisms. Customer-supplied servo motors can be easily integrated into the design. Click here to use our Product Table Finder.

Cup Type Back to top
Features a flexspline with external gear teeth in the shape of a cup. Options available: Standard, high-torque, ultra-flat, lightweight, and big bore.
High torque gear set. The CSG-2A cup type component set gear offers the design engineer high torque with zero backlash in a compact configuration.
Compact and easy to install, Harmonic Drive® CSF series gearing was primarily developed to meet the space constraints of the industry, while preserving performance.
The ultra-flat CSD precision gears are available in seven sizes, opening up new applications for motion control speed reducers.
The CSF-2A-LW is a compact, lightweight component set. 30% less weight compared to our standard CSF component set!
30+% lighter than standard CSG component set! The CSG-2A-LW is a high-torque compact, lightweight component set with optional extra-large bore.
Pancake Back to top
Pancake gears consist of four main parts: Wave Generator, Flexspline, Dynamic Spline, and Circular Spline. Extremely flat and compact, these pancake gears offer the design engineer high ratios in extremely compact configurations. These low cost gears are ideal when price is a factor and zero-backlash is not required.
An FB-2 is a cup type component set, without the bottom of the cup. It offers the design engineer high ratio, in-line mechanical power transmissions in extremely compact configurations.
FR is a heavy duty pancacke gear that uses a double wave generator bearing. By arranging the wave generator bearings in two lines and widening the tooth width of the Circular Spline and the Flexspline, the FR supports high torque capacity.
Silk Hat Back to top
The flexspline of the silk hat gears features a brim that looks very similar to a silk hat, hence the name. The brim acts as a perfect mounting surface, leaving a large through hole.
The SHF-2A zero backlash component set features a large hollow through hole and provides exceptional positioning accuracy in a compact design. Torque: 9.0 ~ 1800 Nm
Available in 10 sizes, this high torque, zero-backlash component set features silk hat brim and a large through hole. Simple and compact design offers the design engineer flexibility. Torque: 23 ~ 3400 Nm
