ISO 8132:2022

Overview

ISO 8132:2022 specifies the standardized mounting dimensions for accessories used with hydraulic single rod cylinders, focusing on two pressure series: 16 MPa (160 bar) medium series and 25 MPa (250 bar) series. Developed by the International Organization for Standardization (ISO), this standard ensures the interchangeability of key hydraulic cylinder accessories, supporting seamless integration and maintenance in fluid power applications. The mounting dimensions are aligned with ISO 6020-1 (for 16 MPa cylinders) and ISO 6022 (for 25 MPa cylinders), allowing for consistent component fit and system design.

Key Topics

• Standardization of Mounting Dimensions: Defined criteria ensure hydraulic cylinder accessories can be used interchangeably across different manufacturers and systems.
• Compatibility: Accessories are compatible with cylinders manufactured to ISO 6020-1 and ISO 6022, enhancing versatility in hydraulic system design.
• Accessory Types: The document covers a comprehensive range of cylinder accessories identified per ISO 6099:
  • AP2: Rod clevis, female thread
  • AF3: Rod flange, circular
  • AB4: Clevis bracket, straight
  • AB3: Clevis bracket, in angle
  • AT4: Trunnion bracket
  • AA4-R/AA4-S: Pivot pins (plain bearing, snap ring or split pin type)
  • AA6-R/AA6-S: Pivot pins (spherical bearing, snap ring or split pin type)
  • AP6: Rod eye, spherical, female thread
  • AP4: Rod eye, plain, female thread
• Dimensional Criteria: Focused only on dimensional compatibility, not on functional or performance characteristics.
• Tolerances: Adopts ISO 286-2 and ISO 2768-1 for linear and angular tolerances.
• Lubrication and Installation: Provides basic instructions for installing accessories and ensuring adequate lubrication.

Applications

• Hydraulic Cylinder Design and Manufacturing: Facilitates the design and assembly of cylinders with readily available, interchangeable accessories.
• Maintenance and Repair: Simplifies part replacement and maintenance by ensuring dimensional compatibility of replacement accessories, reducing downtime.
• System Integration: Enables the combination of cylinders and accessories from different suppliers in industrial fluid power systems without custom modification.
• Industrial Fluid Power Systems: Widely used in industries such as manufacturing, construction, materials handling, and mobile equipment where hydraulic actuation is essential.
• Engineering Documentation: Assures that technical documentation, part catalogs, and references maintain consistency and accuracy in specifying cylinder accessories.
