Overview

This document provides detailed technical specifications and dimensional data for rod end trunnion type pneumatic cylinders, specifically covering bore sizes from 20 mm to 63 mm. It includes information on switch installation methods, accessory dimensions, and various configuration options.

1. Cylinder Types and Switch Installation Methods

• Rod End Trunnion Type (TA): Basic cylinder type with options for switch installation via rail or band methods.
• Switch Installation Methods: Two primary methods are detailed:
  • Rail method
  • Band method
• Special Types: Air cushioned types share needle and port dimensions with the basic type, except for 20 and 25 mm bore cylinders.

2. Dimensional Specifications

The document provides extensive dimensional tables for various bore sizes (20, 25, 32, 40, 50, 63 mm), including:

• Basic dimensions such as bore diameter, stroke length, and collar outer diameter.
• Key parameters like WF, P1, P2 (angles in degrees), b, d, s, and others relevant to cylinder design and mounting.
• Dimensions related to switch installation, including projections and mounting hole sizes.
• Details for rod end trunnion with bracket (option symbol B2), including additional mounting dimensions.

3. Notes and References

• Note 1: Needle relevant dimensions and port sizes for air cushioned types are consistent with the basic type, except for 20 and 25 mm bore cylinders.
• Note 2: For specialized switch types (2-color indicator, preventive maintenance output, off delay, strong magnetic field proof, T1H/V, T8H/V), refer to page 333 for RD, HD, and projecting dimensions.
• Note 3: Configuration components include collar, plain washer, and hexagon socket head cap bolt.
• Note 4: Accessory dimensions are detailed on pages 334 and 335.

4. Mounting and Accessory Details

• Bracket installation dimensions are provided for rod end trunnion types with brackets (option B2).
• Details on bolt sizes (e.g., M8, M10 x 1.25, M14 x 1.5, M18 x 1.5) and thread specifications are included.
• Information on bellows and their impact on dimensions is noted.

5. Summary of Critical Parameters

6. Recommendations and Best Practices

• Refer to specified pages (230, 333, 334, 335) for detailed accessory and special switch dimensions.
• Ensure correct switch installation method is selected based on cylinder type and application.
• Use provided dimensional data for precise mounting and integration in pneumatic systems.
• Consider air cushioned type differences for 20 and 25 mm bore cylinders.

Conclusion

This technical document serves as a comprehensive reference for engineers and technicians involved in the selection, installation, and maintenance of rod end trunnion type pneumatic cylinders with bore sizes ranging from 20 to 63 mm. It emphasizes accurate dimensional data, switch installation options, and accessory compatibility to ensure optimal system performance.
