Regal Rexnord
Precision Gearboxes
Regal Rexnord precision gearboxes are ultra - accurate, low - backlash(often < 1 to 8 arc - min) speed reducers designed for the demands of servo - driven positioning systems, robotics, CNC machinery, and other motion - control applications where angular precision, repeatability, and torsional stiffness directly determine the quality and throughput of the automated process.Unlike general - purpose gearboxes that accept the gear backlash inherent in standard manufacturing tolerances, precision gearboxes are built with profile - ground gears, tightly controlled center distances, and specially designed output - bearing systems that minimize lost motion under reversing and start - stop loads.Under the Electromate, Grove Gear, and Hub City brands, our precision gearbox portfolio spans inline planetary, right - angle helical - bevel, and right - angle worm configurations with standard input flanges that accept any major servo - motor brand — eliminating the motor - adaptation challenges that often complicate precision drive specification.Automation engineers, robotics designers, and machine builders select Regal Rexnord precision gearboxes when the application’s positioning accuracy, path - following fidelity, and long - term repeatability cannot tolerate the gradually increasing backlash that defines general - purpose gearing.With IP65 sealed designs for food, packaging, and machining - center environments, our precision gearboxes enable the highest - performance motion automation across the broadest range of industrial sectors.

<1 to 8 Arc - Min Backlash Precision
Profile - ground gearing with precisely controlled center distances delivers the minimal lost motion that maintains servo - loop stability and positioning accuracy across millions of cycles.
Universal Servo - Motor Input Compatibility
Input flanges and pilot diameters designed to accept any major servo - motor brand(Siemens, Rockwell, Bosch Rexroth, Mitsubishi, etc.) without adapter plates, ensuring optimal drivetrain concentricity.
High Torsional Stiffness & Tilting - Moment Capacity
Integrated angular - contact or crossed - roller output bearings provide the rigidity for direct pinion and rotary - table mounting without additional outboard support bearings.
Planetary & Right - Angle Configurations
Inline planetary for the highest torque density and coaxial motor - load relationship; right - angle helical - bevel for space - constrained applications requiring a 90° motor offset.
IP65 Sealing for Washdown, Machining & Packaging
Sealed input and output with Viton or PTFE lip seals exclude the coolant, dust, and washdown fluids prevalent in CNC, food - processing, and cleanroom environments.
Maintenance - Free, Lubricated -for-Life
Factory - filled with synthetic, high - pressure gear lubricant for the design life of the gearbox in most rated applications, eliminating periodic relubrication maintenance.
Precision Gearboxes in Robotic Arms & CNC Machine Tools
Industrial robots and CNC machine tools demand a level of gearbox precision that directly translates into product quality.The gearbox at each robot axis must transmit torque with zero - backlash reversals to maintain the tool - center - point(TCP) accuracy across millions of weld, paint, or pick - and - place cycles.In a CNC machining center, the ball - screw drive gearbox must provide backlash - free transmission that enables the micron - level linear - axis repeatability required by modern aerospace, medical, and automotive part tolerances.Regal Rexnord Electromate precision planetary and helical - bevel gearboxes, with their sub - 5 arc - min backlash, optimized bearing stiffness, and direct pinion - mount capability, deliver the mechanical precision foundation on which these high - productivity automation systems depend.Our application engineers work with machine builders to model the dynamic response of the gearbox within the complete servo - drive system, ensuring that the gearbox inertia, stiffness, and backlash are correctly represented in the control - loop tuning.
Selecting the Optimal Precision Gearbox for Servo - Drive Applications
Effective precision gearbox selection balances torque capacity, backlash class, inertia ratio, and radial / axial load capacity against the servo motor’s characteristics and the application’s motion profile.Over - specifying backlash(e.g., <1 arc - min for a palletizer where 8 arc - min is sufficient) can needlessly increase system cost.Under - specifying tilting - moment capacity on a gearbox driving a pinion against a rack can result in premature output - bearing failure.Regal Rexnord provides the application - modeling tools and engineering support to define these parameters for each specific motion axis, generating a recommended gearbox part number with supporting life calculations that ensure the gearbox will meet the application’s accuracy and reliability requirements throughout the machine’s target service life.
