how to cut roller chain to length

Roller chains are general purpose mechanical equipment used in a wide variety of industries including automotive, agriculture and manufacturing. However, there are times when roller chain needs to be cut to specific lengths to suit specific applications. While this may seem like a challenging task, it can be accomplished with ease given the right tools and knowledge. In this blog we will provide a detailed step by step guide on how to cut roller chain to length.

Step 1: Gather required tools:
Before starting the cutting process, make sure you have the following tools and materials ready:
1. Goggles
2. Work gloves
3. Tape measure or ruler
4. Roller Chain Break Tool
5. Bench vise or clamping device
6. Metal file or deburring tool

Step 2: Measure and Mark Required Length:
Use a tape measure or ruler to determine the required length of roller chain, and make an exact mark with a permanent marker or similar tool. Make sure the chain is properly tensioned or clamped to avoid any accidental movement.

Step Three: Breaking the Chain:
Take the roller chain breaker tool and line it up with one of the chain links. Use a wrench or box wrench to apply pressure to the tool until the pin pops out of the link. It is important to follow the manufacturer’s instructions that came with the breaker tool, as the process may vary depending on the type of tool.

Step 4: Remove redundant links:
After the chain breaks, remove the excess links until you reach the marked length. It is critical to remove the same number of links from each side to maintain proper alignment.

Step 5: Reattach the chain:
Using a roller chain breaker tool or a coupler link, reattach both ends of the chain to the desired length. Again, refer to the manufacturer’s instructions for proper technique, as it may vary by tool type.

Step 6: Test and Check:
After reattaching the chain, give the chain a gentle tug to make sure it moves freely without any snags or tight spots. This step is critical to guarantee the functionality of the chain and prevent any potential damage or accidents.

Step 7: File or Deburr Cut Edges:
Using a metal file or deburring tool, carefully smooth any sharp edges or burrs from the cutting process. By doing this, you prevent unnecessary wear on the chain, ensuring a longer lifespan.

Step 8: Lubricate the Chain:
Finally, after cutting and smoothing the chain, it is imperative to use the proper lubricant to minimize friction and improve overall performance. Use a lubricant specifically designed for roller chains and make sure it is applied evenly to all moving parts.

Cutting roller chain to the desired length may seem daunting at first, but with the right tools and a systematic approach, it can be done easily. Remember to wear goggles and work gloves throughout to stay safe. By carefully following each step outlined in this guide, you can ensure a properly cut and fully functional roller chain tailored to your specific needs.
