Our precision equipment provides large torque, high-ratios, significant shock-load capabilities and arc-second repeatability. Our near-zero backlash reduction gears are found the world over controlling industrial robots, welding turn tables and positioners, medical imaging equipment, satellite antennas and countless other general industry applications. We currently claim a 70% market share in the industrial robot industry and a 40% market share in the machine tool industry – and our plant manufactures over 25,000 gearboxes per month to supply our worldwide demand. Our 32 subsidiaries and over 4,000 employees worldwide ensure complete customer satisfaction – wherever the final destination of your product may be. For high quality and proven performance, Nabtesco is the preferred choice wherever precise motion is required.
RV-E Gearbox: High-Performance Positioning
By utilizing patented Cycloidal technology, the Nabtesco RV-E Precision Gearbox combines near zero backlash (less than 1 arc-min), large torque capacity (5X e-stop) and integrated support bearings in one complete positioning package.
As a leading manufacturer in the high performance gearing industry, the Nabtesco Cycloidal design provides numerous advantages over competing products in the marketplace. In comparison to Harmonic gearing, the integrated bearings of the RV-E provide superior torsional stiffness, thrust load and overhung moment capacity. The RV-E is also resistant to ‘ratcheting’ or gear slippage, which can occur in high load conditions to Harmonic technology.
The Nabtesco gearbox also provides several advantages over traditional planetary gear technologies, specifically in terms of gearbox dimensional thickness and cost for performance. Planetary gearing requires the addition of stages to achieve higher gear ratios, thus adding additional length to the unit. Further, lower backlash planetary models are only typically available at a premium price. However, Nabtesco Cycloidal technology provides ratios from 40:1 up to 250:1 in the same dimensionally compact configuration – and all Nabtesco RV products are shipped with backlash 1 arc-min or lower, as a standard feature.
The RV-E gearbox is manufactured by Nabtesco, the world’s largest precision cycloidal gearbox manufacturer. Nabtesco has shipped over 2 million precision gearboxes worldwide and continues to be the preferred choice of design engineers the world over for high performance positioning. Common applications include: motion control devices and medical imaging equipment.
RD-C Hollow Shaft/Zero Backlash Gearhead
Nabtesco’s Hollow Shaft RD-C Series gearhead combines high precision (less than 1 arc-min), high torque and a large center through-hole in a completely sealed and ready to mount package. The patented 2-stage design and integrated support bearings provide extreme rigidity, high shock-load and the ability to support heavy external loads. The RD-C is ideal for any application where high-end positioning performance is required.
The large thru-hole (up to 5”) can accommodate cables, shafts, etc. to provide the most efficient and space saving design possible. The main internal angular support bearings provide large moment capacities and negate the need for external support devices – reducing design time and installation costs. Several sizes are available with output torque to 138,768 in-lb; moment capacity to 347,179 in-lb and ratio’s up to 253:1.
