Regal Rexnord
Linear Motion
Regal Rexnord linear motion solutions transform rotary motion into precise, controlled linear movement — the fundamental mechanical action behind positioning stages, robotic actuators, material - handling gantries, medical - device drives, and automated assembly equipment.Our linear motion portfolio, encompassing ball screws, lead screws, linear actuators, linear guides, and complete pre - engineered linear positioning stages, provides the building blocks that machine designers, automation engineers, and OEM manufacturers need to create repeatable, high - speed, and load - capable linear movement systems.Under the Warner Electric and Browning brands, these products span precision - ground ball screws with sub - 0.001 inch lead accuracy for CNC and semiconductor equipment, rolled ball screws for economical industrial positioning, Acme lead screws for high - load manual and low - duty powered applications, and electric linear actuators that integrate the motor, screw, and housing into a ready - to - install push / pull module.Design engineers select Regal Rexnord linear motion components when their machine must position, push, pull, lift, or traverse a load with defined accuracy, speed, and repeatability — and when the quality of the linear motion system defines the productivity and quality of the machine itself.

Integrated motor, screw, and bearing - housing modules that simply bolt in and wire up — replacing complex fluid - power systems for pushing, pulling, and lifting functions in industrial and mobile equipment.
Rolled Ball Screws for Cost - Sensitive Automation
An economical alternative to ground screws, providing 90 % + efficiency and smooth operation for general positioning on packaging machines, material - handling systems, and agricultural automation.
Acme Lead Screws & Nuts for Manual & Low - Duty Drives
Self - locking thread profiles and durable bronze or polymer nut materials for valve actuators, jack mechanisms, and manual positioning stages where simplicity and holding ability are paramount.
Linear Guides & Rails for Load Support
Hardened and ground rail - and - bearing - block systems that carry the loads and moments of linear motion stages, enabling cantilevered and multi - axis machine configurations.
Custom End - Machining & Integration Services
Shaft ends machined for the specific motor coupling, bearing journal, and sensor - trigger requirements of the customer’s design, reducing assembly time and ensuring alignment.
Ball Screws in CNC & Semiconductor Manufacturing Equipment
CNC machine tools, semiconductor wafer - handling robots, and medical diagnostic instruments share a requirement for extremely precise, repeatable linear positioning that directly determines product quality.Regal Rexnord precision - ground ball screws provide the lead accuracy, axial stiffness, and low - friction smoothness that high - gain servo systems require to maintain tool - path or positioning accuracy under varying cutting loads or high - acceleration motion profiles.Our ball - screw engineering team works with machine builders to model the screw’s critical speed, buckling load, and stiffness within the machine structure, ensuring that the linear - drive axis meets the dynamic performance targets that the machine’s productivity and part quality depend upon.With preloaded ball nuts that eliminate backlash(essential for contour milling and pick - and - place accuracy), our ball screws form the precision backbone of some of the world’s most accurate production equipment.
Electric Linear Actuators as a Clean, Efficient Alternative to Hydraulic & Pneumatic Cylinders
Many industrial and mobile - equipment linear - motion applications historically served by hydraulic or pneumatic cylinders are transitioning to electric linear actuators for compelling reasons: no oil leaks, no compressed - air energy waste, precise position control, and the ability to program multiple stop positions and force profiles.Regal Rexnord Warner Electric linear actuators provide these advantages in a sealed, IP66 - rated package that bolts into the same envelope as the cylinder it replaces.Applications include agricultural planter row - unit adjustment, construction - equipment hood and door actuation, and industrial damper and diverter - valve positioning.The switch to electric actuation eliminates the hydraulic power unit or compressed - air infrastructure, simplifies machine design, and provides the programmability and data feedback that enable the “smart machine” capabilities demanded by modern automation.
