For a variety of systems with mechanical power transmission, Tsubaki offers many different types and sizes of ANSI and ISO British Standard roller chains and has an extensive inventory that is readily available for urgent needs. As there are many types and sizes of roller chains used on a multitude of different equipment, measuring the key dimensions and identifying a roller chain you have is very critical to ensure proper interaction with other components in your machine.
The following article provides an overview of how to properly measure and identify roller chains.
How to Measure and Identify Roller Chains
There are several crucial elements to measure simply with a caliper when identifying a roller chain for an application. Those dimensional measurements include:
- Pitch: The pitch is the distance between the center of a pin to the center of the adjacent. Roller chains with smaller pitches are generally used for light-duty work, while roller chains with larger pitches are typically utilized for heavy-duty applications.
- Roller diameter: The roller diameter refers to the thickness of the roller components that can spin freely on roller link. In some applications, the rollerless chains, such as ANSI standard sizes 25, 35, 45,55,65, and so on, are used. It is important to note that their roller diameter refers to the thickness of the bushing instead of roller.
- Roller width: The roller width is the inner distance between inside plates of roller link.
- Side plate height: Side plate height refers to the height of the inside or outside plate. Height differs between inside and outside plates for most standard single-pitch roller chains while inside plates have the same height as outside plates for all double-pitch roller chains.
- Side plate thickness: The side plate thickness is the thickness of the inside or outside plate. It is recommended to measure the thickness of both inside and outside plates since not every roller chain size has inside and outside plates that have the same thickness.
- Pin diameter: The pin diameter refers to the thickness of the pin. If available, it is easier to measure the pin thickness of connecting (master) link or offset (half) link.
Verifying the measurements of these elements properly is key to making sure the roller chain operates at its peak performance. With these measurements in hand, you can identify a right chain size based on the tables of dimensions included in our roller chain product page or roller catalog.
