Applications
Manufacturing is only one area. See how our products may touch your everyday life.
Robot-Assisted Rehabilitation Equipment
Nabtesco precision reduction gears drive the smooth, controlled motion behind robot-assisted rehabilitation systems, helping patients rebuild strength and mobility safely.
Automated Vacuum Packaging Machines
From food processing to industrial lines, our compact cycloidal gearboxes deliver the accuracy and reliability automated packaging demands.
Satellite & Antenna Positioning
Near-zero backlash gearing keeps ground stations and tracking antennas on target, even under heavy wind loads.
Warehouse & Logistics Automation
Integrated AGV drive units keep autonomous fleets moving with precise, repeatable motion across the modern fulfillment floor.
Semiconductor Wafer Handling
Nabtesco reducers deliver the precise, repeatable motion that wafer-handling robots and process equipment demand.
Resource Library
The Two-Stage Cycloidal Design Behind RV Gears
Rolling contact keeps RV gear backlash low, and the pin and gear structure resists shock loads.
Mecanum Wheel Drives With RV Gears For AGVs
Omnidirectional movement for large-payload AGVs, with the RV gear built into the wheel.
Selecting The Right Gear For Antenna Positioners
RDS-C and RV-C hollow shaft gears for antenna positioners: accurate pointing, smooth tracking.
