MAG COUPLED CYLINDER

Product catalog summary
Features
The document highlights the features of Tolomatic's magnetically coupled cylinders and slides, focusing on their durability and maintenance-free design. Key features include engineered elastomer wipers to prevent leaks, anodized aluminum heads for corrosion resistance, and a field-repairable design. The cylinders can be actuated by air or oil up to 100 PSIG and offer flexible mounting options.
Performance
This section details the theoretical force versus pressure for different bore sizes, emphasizing magnetic coupling strength and tube deflection. Performance graphs for various models show coupling force and stroke length.
Specifications and Dimensions
Specifications for the MG and MGS series include bore size, weight, maximum stroke, bending moment, and pressure limits. Detailed dimensional drawings are provided for accurate installation and integration into systems.
Mounting Options
The document describes foot and floating mount options. Foot mounts are made from plated stamped steel and can be attached at both ends of the cylinder. Floating mounts compensate for non-parallelism between the cylinder and guided loads, enhancing actuator block bearing life.
Sensors and Accessories
Switches and proximity sensors are available in Reed, Hall-effect, and Triac types, with options for quick-disconnect couplers. Shock absorbers are also offered for smoother deceleration and reduced maintenance.
Application and Ordering Guidelines
Guidelines for selecting the appropriate MG or MGS model based on application requirements are provided. Ordering codes and application data worksheets assist in specifying the correct product configuration.
Specifications and Load Considerations
The document outlines specifications for magnetically coupled slides (MGS) with different bore sizes: MGS038, MGS062, and MGS100, each with specific stroke lengths. It emphasizes the importance of determining the nature of the load and the effect of bending moments. If the load is centered, bending moments are negligible. Otherwise, formulas are provided for off-center loads.
Bearing Rod Load Capacity
To ensure the load weight and stroke length are within capacity, users should reference the Load Weight vs. Stroke chart. If the intersection of load weight and stroke falls below the curve, the cylinder is suitable. Otherwise, a larger bore size is recommended. Rod deflection should not exceed 0.30 inches.
Coupling Force and Internal Bumper Capacity
The required coupling force should be checked against the Mag Coupling Strength chart. If the load exceeds the coupling force, a larger actuator is needed. For internal bumpers, the Cushion Data chart should be consulted to ensure velocities are within limits.
Loading Equation and Bending Moments
Key variables include distances between shaft centers and load centers, load per shaft, and maximum bearing sliding loads. Equations are provided to calculate bending moments and ensure they are within acceptable limits.
Application Guidelines
General guidelines for Tolomatic actuators are provided, emphasizing consultation for unconventional applications. Cushion needle adjustments should be made carefully for smooth deceleration.
Lubrication Guidelines
Tolomatic actuators are prelubricated, but external lubricators can extend service life. The use of dry, filtered air is recommended, and specific guidelines for oil lubricators are provided. In sanitary environments, food-grade lubricants are necessary.
Velocity Calculations
Final velocity calculations are crucial for determining inertial forces. The document provides guidelines for calculating final velocity, considering acceleration and deceleration at stroke ends.
Ordering Information
Details on ordering foot mounts, floating mounts, and switches are provided, including model, bore, and stroke options. Specific codes for ordering service parts and configuration are included.

Floating Mount Bracket ORDER CODE The integral floating mount bracket is available for applications in which a load is externally guided and supported and there is a need to compensate for nonparallelism between the cylinder and the independently-guided load. Loads which are not parallel to the cylinder may result in the cylinder binding if the floating mount bracket is not used. Also, use of the floating mount is highly recommended to provide easier set-up of guide/support system and to help increase actuator block bearing life.
