ISO6431 Standard Cylinder

Characteristics:

◆ This series of cylinder conforms to: ISO6431 standard.

◆ There is an adjustable buffers at the terminals of the cylinder except for mounted cushion.

◆ We can offer different kinds of mounting style according to ISO6431 standard, like Foot mounting, Front flange mounting, Rear-flange mounting, and so on.

◆ Different thread type can be offered according to customers' requirements, e.g.: BSP, NPT etc.

◆ Needn't lubricate on piston rod by oil.

Definition

An ISO 6431 cylinder refers to a universal, basic double-acting pneumatic cylinder that fully complies with the dimensional and pneumatic interface specifications set by the ISO 6431 standard. It does not denote a specific brand or model but rather a design and manufacturing specification. This Piston Cylinders conforming to this standard are directly interchangeable in mounting dimensions regardless of their place of origin.

Features:

Multiple installation methods:The ISO 6431 standard cylinder supports multiple standardized mounting methods, including precise hole spacing, diameters, and threads for various mounting forms such as front flange, rear flange, foot mounting, and clevis mounting.

Standardized Bore Sizes and Piston Rods:Bore sizes are standardized (e.g., 32mm, 40mm, 50mm, 63mm, 80mm, 100mm, etc.).

Standardized Performance Parameters:Rated working pressure range (typically 0.1 to 1.0 MPa).

Modular Design:The cylinder itself serves as a base module, compatible with ISO-standard accessories such as magnetic switches (for position detection), cushion adjustment valves, and mounting brackets.

Typical Structure:It usually features a tie-rod construction, comprising a cylinder tube, front and rear end caps, a piston, a piston rod, and seals. This design ensures robust construction and relatively straightforward maintenance.

Key Advantages

Exceptional Interchangeability: The greatest advantage is that piston cylinders of this series can be quickly sourced from any global supplier as directly replaceable spare parts, significantly reducing downtime.

Simplified Design and Procurement: Engineers only need to specify the bore size and stroke compliant with ISO 6431 during design, streamlining the design process and procurement specification development.

High Reliability and Quality Assurance: Meets basic performance, safety, and durability requirements, ensuring quality.

Supplier Availability: Due to their high universality, users can consolidate suppliers and reduce procurement costs.

Extensive Accessory Support: A wide range of compatible cylinder accessories (sensors, mounting components, couplings) is available for selection.

Typical Application Areas

ISO 6431 cylinders are widely used in almost all industrial automation fields due to their universal, reliable, and easily replaceable characteristics:

General Industrial Automation: Basic actions such as material handling, pushing, clamping, lifting, and positioning.

Packaging Machinery: Actuators for units like box loading, sealing, and palletizing.

Automotive Manufacturing and Assembly: Conveyor line positioners, fixture actuators, and assembly tools.

Food and Beverage Processing (typically using stainless steel variants): Operations such as sorting and bottling in clean environments.

Machine Tools and Machining Centers: Power sources for door switches, workpiece clamping, or tool-changing mechanisms.
