Product catalog summary

Overview of RSA & GSA Electric Rod-Style Actuators
The RSA and GSA electric rod-style actuators are designed for flexibility and customization. The RSA is a basic screw-driven actuator, while the GSA offers additional guidance and support for loads. Both models are customizable with various stroke lengths and can be shipped within five days. They support multiple motor mounting options and are compatible with brushless servo and stepper motors, or users can supply their own motor. The actuators feature three drive screw technologies and 12 mounting and rod end options, backed by over 50 years of experience and a satisfaction guarantee.

Specifications
The RSA can handle thrusts up to 7,350 lbf and speeds up to 123 in/sec, with stroke lengths up to 60 inches. The GSA offers thrusts up to 2,670 lbf with similar speed capabilities. Screw/nut types include solid, ball, and roller options, each with different performance characteristics.

Applications
These actuators are suitable for applications such as animation, assembly machinery, automotive, clamping, conveyors, hydraulic replacement, machine tools, medical equipment, packaging, and robotics. They are designed to replace pneumatic and hydraulic systems, offering a more efficient and flexible solution.

Features and Options
The RSA features solid nuts for quiet performance, ball nuts for efficiency, and roller nuts for high thrust and life ratings. The design prevents contaminants from entering the housing, ensuring extended actuator life. The GSA includes a guided rod design for load guidance and support, with options for oversized rods and corrosion-resistant materials. Both models offer various mounting options, motor orientations, and ingress protection kits.

Performance and Life Expectancy
The actuators are designed for maximum durability, with high thrust bearing assemblies and precision machined surfaces. The life expectancy of the ball and roller screws is expressed in terms of linear travel distance, with graphs provided for estimation. Proper lubrication and maintenance are essential for achieving the expected lifespan.

Specifications and Application Data
The document provides detailed specifications for RSA and GSA actuators, including size, screw diameter, screw type, lead accuracy, backlash, maximum thrust, dynamic load rating, base actuator inertia, breakaway torque, and moving parts weight. Various screw types such as solid nut, bronze nut, ball nut, low-backlash ball nut, and roller nut are described.

Procedures
Procedures for calculating RMS thrust and velocity for severe duty applications are outlined, including formulas for determining lubrication intervals. The recommended margin of safety for servo motors is 15%.

Norms and Recommendations
Actuators have two speed/thrust curves: continuous duty and intermittent (peak) duty. The RMS thrust must fall within the continuous duty region, and the application maximum thrust must be under the peak thrust of the actuator. In contamination-sensitive applications, it is recommended to replace the grease zerk with a plug.

Data Summary
Tables with detailed data on screw buckling load, thrust, velocity, and actuator performance capabilities are included. Information on various sizes and configurations, including maximum stroke, screw code, and turns per inch, is provided.

Key Parameters
- Maximum Stroke: Varies by size (e.g., 18, 24, 30, 36 inches)
- Screw Types: SN, BZ, BN, BnL, RN
- Thrust and Velocity: Calculated using RMS formulas
- Lubrication: Required periodically with specific intervals and quantities

Limitations
The dynamic load rating reflects 90% reliability for 1 million linear inches of travel for RN, BN, and BnL screws. Maximum continuous dynamic thrust is subject to thrust x velocity limitations for SN and BZ screws.

Best Practices
Ensure that the RMS thrust and velocity calculations are within specified limits and follow recommended lubrication practices to maintain actuator performance.

Precision and Operating Environment
Details on precision repeatability and operating environment factors such as temperature and contamination are provided. Contact information is required for further assistance.

Motion Profile and Load Requirements
The document outlines the motion profile for extend and retract movements, including move distance, time, speed, and dwell time. It specifies load and force requirements in both U.S. Standard and Metric units.

Sizing and Selection Guidelines
A step-by-step guide for selecting the appropriate actuator is provided, including establishing motion profiles, selecting actuator type and size, verifying critical speed and axial buckling strength, and comparing application parameters to actuator capacity.

Temperature and Torque Considerations
Guidelines for temperature considerations and calculating total torque requirements are included. It advises selecting a motor and controller based on these calculations.

Actuator Configuration and Options
Details on motor-actuator configurations, sensor options, rod end options, and mounting options are provided. A comprehensive list of available options and accessories is included.

Ordering and Replacement Kits
Information on ordering bearings, guide rods, stop collars, and replacement kits is included, with part numbers and descriptions for various components.

Customer Service and Support
Tolomatic emphasizes excellent customer service and technical support, industry-leading deliveries, and innovative products. The document highlights the availability of online sizing and selection software, as well as 3D models and 2D drawings.

Additional Products
The document briefly mentions other Tolomatic products, including power transmission products, electric products, and pneumatic products.
