778322 COUPLING – Centaflex Replacement Rubber Coupling (2019608, 3633643)
Understanding Centaflex CF-A Series Rubber Couplings
The part numbers 778322, 2019608, and 3633643 correspond to the Centaflex CF-A series flexible rubber couplings. However, relying solely on these numbers is not enough to ensure you are selecting the correct size for your machine. If you only go by these numbers, you may end up with the wrong coupling size, leading to compatibility issues.
To accurately confirm the right Centaflex CF-A coupling, follow this simple two-step process.
Step 1: Identify the Hole Type
One critical factor in choosing the right coupling is the hole type. Many buyers overlook this detail, but selecting the wrong hole type means you may need to adjust the coupling bolt or pin.
There are two types of coupling holes in the Centaflex CF-A series:
🔹 A-Type (Straight Hole) – Also known as CF-A-OS
🔹 AS-Type (Step Hole) – Also known as CF-A-O0
📌 Why does this matter?
If you select the wrong hole type, you may need to use a different coupling bolt or pin. Don’t worry—our guide on coupling spline bolts and pins can help you make the correct adjustments.
Step 2: Confirm the Size
Once you’ve identified the hole type, the next step is to confirm the size of your Centaflex rubber coupling.
✔ Easy Method: Some couplings have the size printed directly on the rubber next to the word “size”. If you find this, you’re in luck—it’s a quick confirmation!
✔ Difficult Cases: If your machine broke down, the flexible coupling may be damaged, or the size marking may have worn off, making identification harder.
What to Do If You Can’t Find the Size?
🔹 Contact your equipment dealer – Send them photos and dimensions of your coupling for verification.
🔹 Reach out to a flexible coupling supplier – A professional supplier (like us!) can analyze the dimensions and confirm the correct size for you.
Bonus Tip: If you don’t want to stress over the details, just send us the photos and measurements of your coupling. Then sit back, enjoy your coffee, and let us handle the rest! ☕😉
