Description

4015 #40 Industrial Roller Chain Master Link – Economy Grade


The 4015 #40 Master Link is an economy-grade connecting link designed to work with #40 pitch roller chains, including the 40-1R-10 economy chain. Commonly referred to as a quick-release link, this component provides a fast and convenient way to connect or disconnect chain segments without the need for a chain breaker.


Perfect for light-duty applications and general machinery, the 4015 master link allows for easy maintenance, chain length adjustments, or replacements in non-performance setups.


Note: This master link is not preferred for racing or high-performance use. In high-stress applications, always use a chain breaker to create permanent chain lengths to avoid the risk of link separation.


Key Features:

  • Part Number: 4015
  • Chain Pitch: #40
  • Link Type: Master Link (Connecting / Quick-Release)
  • Compatibility: 40-1R-10 Economy #40 Chain
  • Material: Economy-grade steel
  • Tool-Free Installation: No chain breaker required for basic setup


Ideal For:

  • Light-duty machinery and equipment
  • DIY projects
  • Utility go-karts and lawn equipment
  • General maintenance and chain replacement


Performance Notice:

For racing or high-load applications, we recommend removing the master link and creating a solid, uninterrupted chain with a chain breaker tool. This minimizes the risk of mechanical failure under stress.


FAQ

1. What is a master link?

A master link (or connecting link) is a removable piece that lets you join or separate a roller chain without special tools, making maintenance and length adjustments easier.


2. Can I use this in high-performance or racing applications?

No. This master link is not designed for racing or high-torque use. In those scenarios, it’s best to use a chain breaker and create a solid, uninterrupted chain to avoid link separation.


3. What chain types is it compatible with?

The 4015 master link is made for #40 pitch roller chains, including the 40-1R-10 economy chain. It is not compatible with #35, #41, or #420 chains.


4. Is this link reusable?

Yes, it can be reused in low-load, light-duty applications, but it should be inspected regularly for wear or damage.


5. Do I need a tool to install it?

No special tools are required for basic installation. The clip-style design allows for quick connection and removal by hand or with pliers.


6. What’s the difference between a half link and a master link?

A master link connects full chain links together, while a half link adjusts chain length by half a pitch. Both are used for chain assembly but serve different functions.
