WHY RACO MA SERIES

WHEN LOAD PROFILES DEMAND MORE THAN A STANDARD ACTUATOR

Modular by Design

Motor type, screw choice, stroke length, and voltage can each be selected independently. Align with your existing drive setup without the delays of custom fabrication.
Broad Force Range

Multiple frame sizes cover 110 lbf through 225,000 lbf. Engineers can select a frame sized precisely to the application load profile, avoiding oversized, overpriced units.
Servo-Ready Architecture

Ball screw options and servo motor compatibility make the MA Series suitable for closed-loop positioning systems where repeatability and duty cycle are non-negotiable.
Scalable Across Programs

Consistent platform architecture across frame sizes lets procurement teams standardize on a single actuator family and apply it across multiple production lines or machine generations.
Domestic Engineering Support

RACO operates from Bethel Park, PA. Regional OEM manufacturers get direct access to applications engineers. No overseas queues for configuration support, CAD files, or documentation.
3D CAD on Request

Fully validated 3D CAD models for every MA Series configuration are ready right away. Import the geometry straight into your assembly to check clearances before fabrication begins.

PRODUCT OVERVIEW A Heavy Duty Linear Actuator System That Adapts to Your Drive

The MA Series is RACO's flagship modular linear actuator system. A heavy-duty electric cylinder platform designed for demanding industrial applications where force, precision, and motor flexibility must coexist in a single unit.

Unlike fixed-configuration actuators, the MA Series separates motor selection from mechanical specification. Engineers can attach a standard RACO motor, an AC gear motor, a DC gear motor, or a servo drive to the same mechanical housing without modifying the actuator body.

This modularity directly solves one of the most persistent challenges in machine design: motor standardization. Facilities that have already standardized on a particular motor frame or drive ecosystem can integrate the MA Series without redesigning motor mounts or drive electronics. The actuator adapts to the existing drive infrastructure.

SCREW DRIVE OPTIONS

ACME or Ball Screw: Select Your Performance Profile

Cycle frequency, load-holding requirements, and positional accuracy targets collectively determine which drive is right for your application. Both ACME and ball screw configurations are available across the applicable MA Series frame sizes. Select the one that matches your performance envelope, not the nearest available option.

ACME SCREW

SELF-LOCKING · ECONOMICAL · PROVEN

Geometric self-locking, load retention requires no powered brake or holding circuit
Lower per-unit cost for moderate-cycle duty applications
Available on all MA Series frame sizes, including the highest-force configurations
Suited to clamping, press tooling, valve actuation, and gate-positioning tasks
Reduced maintenance burden, no recirculating ball element to inspect or replace
Reliable load retention through power interruptions without auxiliary brake hardware

BALL SCREW

HIGH ACCURACY · HIGH EFFICIENCY · HIGH CYCLE

Reduced mechanical losses for installations where energy consumption is a design constraint
Tighter positional accuracy and move-to-move repeatability versus the ACME equivalent
Available across the MA Series frame sizes in selected drive configurations
Designed for servo motor pairing and encoder-based closed-loop control
Handles high-frequency cycling and continuous motion profiles without degrading accuracy
The correct selection wherever cumulative positioning drift cannot be tolerated

MOTOR & DRIVE COMPATIBILITY

ONE PLATFORM. FOUR DRIVE CONFIGURATIONS.

Because the MA Series separates the mechanical drive from the power source, system integrators aren't locked into a single motor type. Four motor configurations are supported across the platform — attach what your control architecture already calls for.

STANDARD RACO MOTOR

Three-phase · Multi-pole · Industrial duty
AC GEAR MOTOR

Single or three-phase · Compact gearhead integration
DC GEAR MOTOR

24V DC · Mobile and battery-powered systems
SERVO MOTOR

Closed-loop positioning · Encoder-compatible

TARGET APPLICATIONS

Where Industrial Linear Actuators Are Specified

Engineers in force-critical industries reach for the MA Series when standard catalog actuators can't meet the load spec, the stroke, or the motor interface their machine demands. These are the environments where the platform earns its place.

Heavy Industrial Machinery

Hydraulic press replacements, die-change actuators, conveyor divert mechanisms, and clamp tooling running multi-shift production schedules at sustained force outputs demand an actuator with proven industrial duty ratings.
Aerospace & Defense

Structural test rigs, ground support actuators, cargo handling systems, and flight control surface test stands require a linear electric actuator that meets the force and accuracy levels the application actually demands.
Energy & Utilities

Pipeline valve actuation, spillway gate control, solar array tracking drives, and turbine blade positioning involve long strokes, high sustained loads, and installations that may run unattended for extended periods.
Automotive Manufacturing

Welding fixture locators, body panel transfer tooling, chassis assembly positioners, and press-fit stations require custom linear actuators that maintain the same position shift after shift, with service intervals long enough to avoid becoming a line availability problem.
Material Handling

Scissor lift tables, loading dock equipment, pallet transfer systems, and heavy load positioners benefit from ACME screw geometry; loads are mechanically retained at any stroke position without a powered holding circuit, even when the machine loses power mid-cycle.
Medical & Lab Automation

Diagnostic imaging platforms, surgical table elevation systems, sample processing equipment, and laboratory automation cells run in noise-sensitive environments where smooth, repeatable linear motion is a clinical requirement.

Talk to an Engineer Before You Spec

RACO's applications team in Bethel Park, PA, works with you directly on frame selection, screw type, motor pairing, and stroke configuration — so the actuator you order fits the machine you're building. Technical drawings and 3D CAD files are available at no charge before you commit to a purchase.
