Harmonic Linear Drive (HLD)
No Gearbox Needed!
Saves cost!
Harmonic Linear Drive (HLD)
No need for Motor Adapters!
Saves EVEN MORE cost!
Harmonic Linear Drive (HLD)
Nearly ZERO backlash!
60 micron Bi-direction repeatability
Harmonic Linear Drive (HLD)
No brake required! HIGH THRUST
• Perfect for vertical gravity loads or constant load applications
• Over 420N achievable from SM23165DT motor
Harmonic Linear Drive (HLD)
• Smallest footprint in its load range
• Compare to conventional ballscrew and belt drives
• Many support rail configurations available
Harmonic Linear Drive (HLD)
Available Configurations2.5mm/rev (equiv. to 40:1 gearbox)5mm/rev (equiv. to 20:1 gearbox)10mm/rev (equiv. to 10:1 gearbox)12.5mm/rev (equiv to 8:1 gearbox)
Top Speed Increases.

Increases
Harmonic Linear Drive (HLD)
Goes Where Others Can’t!• Stroke lengths over 3
meters available• Custom lengths
available in 1mm increments
• Rated speed does not drop off as stroke length increases
Apply as you would a traditional ballscrew without concerns of critical speed limits on long stroke!
Harmonic Linear Drive (HLD)
Internal Rollers Type
• Fully supported by internal roller wheels
• Smallest profile• Used in specific
applications only, limited loading and moment capability
Harmonic Linear Drive (HLD)
Single Rail Type
• Higher load capacities and moment load capabilities
• 2x Self-Lubricating, sealed bearing blocks, suitable for dirty environments
• Standard for most apps
Harmonic Linear Drive (HLD)
Dual Rail Type
• Most robust unit; highest load capacities and moment loading capabilities
• 4x Self-lubricating sealed bearing blocks can handle dirt and dust
• C-Channel carriage for maximum configurability

How does it work?
Drive End
Idle End
Carriage Pulleys
Differing diameters of the pulleys cause a harmonic gearing effect
Harmonic Linear Drive (HLD)
Mechanical Concept
Harmonic Linear Drive (HLD)
ACME Screws Ball-ScrewsHLD
high static-load considerable dynamic thrust
very difficult to back-drive
have the highest static thrust load capability not easy to back-drive
have the highest driving thrust load capability but easy to back-drive
Harmonic Linear Drive (HLD)
Competitive analysisNote: There are NO direct competitive products to the
HLD anywhere. It is unique!Offers benefits of both belt-driven AND ballscrew driven systems!
Conventional Belt• System price• Speed• Length
Ball-Screw/Lead Screw• Precision• Thrust• Static Load

Harmonic Linear Drive (HLD)
Ideal applications
• Long-stroke Medium to High Speed applications• Medium to High Thrust applications• Wherever High Stiffness (in direction of travel) is needed• Where ball-screws cost too much• In vertical loads where back-drive is a problem• In tight holding applications such as:
• Back-stop gauges• Material saw stop jigs• Long-stroke high thrust gantries

• H3 – HLD designator• STROKE – from 112mm to 3200mm!• PITCH – in mm/rev• RAIL – A, B, E for none, single, or dual rail respectively• MOTOR – SM23165DT standard, others available• OPTION – Coded for communications, orientations, etc.
L70 Single-Rail Ballscrew
L70
L70 Single Rail Ballscrew
Key Features• 5mm or 10mm /rev Ball-Screw• Up to 600mm Stroke• Up to 200N Dynamic Thrust Load• Maximum Stroke to Total-Length Ratio• Minimal Cross-Section w/Small Footprint• Open-sided for Easy Mounting• Directly Stackable in X-Y Configuration• Direct mount to HLD

Competative Analysis
• Note: Although there are similar sized Ball-Screw Actuators, due to the mounting flexibility and open side, the L70 stands on its own as a viable alternative to conventional open framed Actuators.
• The open side makes it completely unique in the market
• Actuators comparable in cross-section are typically machined rail-body types with far less moment loading or thrust ratings
XL100 Dual Rail Ballscrew
XL100
XL100 Dual Rail Ballscrew
Feature Overview• 5mm or 10mm Ball-Screw• Up to 600mm Stroke• Up to 200N Dynamic Thrust Load• Easy Mounting “Waist” Access Holes• Wide Dual Rail Support for High Moment Loading• Directly Stackable in X-Y Configuration• Up to 6 Limit Switches

X-Y configuration with SM23375Ds
XL100 Dual Rail Ballscrew
XL100 Dual Rail Ballscrew
Competitive Analysis• More robust- Higher moment capability compared to L70
• Closed frame
• Highest accuracy & repeatability of ballscrew line
• The XL100 has the appearance of a precision stage and yet has the price of a conventional Actuator.
• Note: XL100 does not have the high flatness/straightness specs of a true linear stage. It is an actuator.
