First off, let's talk about what an ISO 6164 Square Flange is. It's a type of hydraulic flange that's widely used in various applications, from industrial machinery to mobile equipment. These flanges are designed to connect hydraulic hoses and pipes securely, ensuring a leak-free and reliable hydraulic system.

Now, onto the main topic: the standard dimensions of an ISO 6164 Square Flange. The dimensions of these flanges are specified in the ISO 6164 standard, which is an international standard that defines the requirements for hydraulic flanges. The standard covers a range of sizes and pressure ratings, so you can find the right flange for your specific application.

One of the key dimensions of an ISO 6164 Square Flange is the bore size. The bore size refers to the diameter of the hole in the center of the flange, which is used to connect the hydraulic hose or pipe. The bore size is typically specified in millimeters, and it can range from 6 mm to 50 mm or more, depending on the size and pressure rating of the flange.

Another important dimension is the flange size. The flange size refers to the overall dimensions of the flange, including the length, width, and height. The flange size is also specified in millimeters, and it can vary depending on the bore size and pressure rating of the flange. For example, a smaller bore size flange may have a smaller overall size, while a larger bore size flange may have a larger overall size.

In addition to the bore size and flange size, the ISO 6164 standard also specifies other dimensions, such as the bolt circle diameter, the number and size of the bolts, and the thickness of the flange. These dimensions are important for ensuring a proper fit and connection between the flange and the hydraulic hose or pipe.

So, why are the standard dimensions of an ISO 6164 Square Flange so important? Well, for starters, using a flange with the correct dimensions is essential for ensuring a leak-free and reliable hydraulic system. If the flange is too small or too large, it may not fit properly, which can lead to leaks and other problems. Additionally, using a flange with the correct dimensions can help to ensure that the hydraulic system operates safely and efficiently.

As a supplier of ISO 6164 Square Flanges, I understand the importance of providing high-quality flanges that meet the standard dimensions. That's why I work closely with my manufacturers to ensure that all of my flanges are made to the highest standards and meet the requirements of the ISO 6164 standard.

In addition to ISO 6164 Square Flanges, I also offer a range of other hydraulic flanges, including SAE Socket Weld Flange and SAE Metric Threaded Flange. These flanges are also designed to meet the highest standards and provide a reliable and leak-free connection for your hydraulic system.
