In this article, we will explain what a 40 chain is, share its roller chain dimensions, and help you learn how to measure it correctly. We will use the PAS framework to show you the problem many face, the pain from inaccurate chains, and our strong solution that brings you high-quality chains every time.
Our manufacturing strengths mean you get a chain that meets ANSI chain standards and even ASME B29.1 guidelines. We craft chains that are strong, reliable, and perfect for many uses—from conveyor systems to machinery. Read on to see how our expertise can solve your issues.
Many businesses face trouble finding the right chain for their needs. Here are some of the problems:
When a chain does not meet its expected roller chain dimensions, it can make your work slow and even unsafe. You may worry if your machine will stop working during a busy day. You may get lost with the many technical details and ISO 606 comparisons.
Imagine you are in the middle of an important run. Your machine is set in conveyor systems and you trust its chain to keep things moving. But then, you find the chain is not the right size!
You need a clear, trusted guide to help you select and use the best 40 chain. We know the pain you face with a chain that fails you at the worst time.
We are proud to offer 40 chains that are made with care. Our manufacturing strength is our strong point. We make chains that are:
Our strong manufacturing means you get a chain that meets every needed requirement. You can trust our chain to keep your machines running day and night.
A 40 chain is a type of roller chain. It has specific dimensions that make it the right size for many machines. Let’s break down its roller chain dimensions:
| Parameter | Value | Notes |
|---|---|---|
| Pitch | 0.5 inches (12.7 mm) | The distance from one pin center to the next[^2]. |
| Roller Diameter | 0.306 inches (7.77 mm) | The diameter of the roller, key in smooth motion. |
| Inner Width (B1) | 0.312 inches (7.92 mm) | The space between the inside plates. |
| Pin Diameter (E) | 0.141 inches (3.58 mm) | The pin that holds the chain together. |
| Tensile Strength | ~6,200 lbs | The chain’s strength, it can hold heavy loads. |
These numbers follow ANSI chain standards. They help you see that a 40 chain is built to be strong and safe. Using calipers and careful chain pitch measurement, you can confirm your chain meets these dimensions.
You must know how to measure your chain to be sure you have the right one. Use these simple steps:
Measure the Pitch:
Check the Roller Diameter:
Measure the Inner Width:
Verify the Pin Diameter:
Test the Tensile Strength (Optional):
If any measurement is off, use our guide to correct the size or replace the chain to avoid expensive downtime.
Not every chain is made equal. Here is a table to help you compare the 40 chain to other types:
| Chain Size | Pitch | Tensile Strength | Use Case |
|---|---|---|---|
| #35 | 0.375 inches (9.525 mm) | 4,700 lbs | Light-duty work and small conveyors |
| #40 | 0.5 inches (12.7 mm) | 6,200 lbs | Medium-duty systems, conveyor systems, farm gear |
| #50 | 0.625 inches (15.875 mm) | 8,500 lbs | Heavy-duty tasks, mining, and construction |
Notice that the 40 chain stands out in many cases due to its balance of size and strength. This data is based on trusted sources that follow ANSI/ASME guidelines.
