Unlocking Precision: A Guide to Calculating Chain Length, Links, and Lock Type for Sprockets

Updated: Dec 5, 2023

Calculator to calculate chain links required for collecting two sprockets

In the intricate world of sprocket-driven conveyor rollers, the assembly of chain loops is a crucial task.

Whether it's ensuring the right number of links or grappling with half lock challenges, precision is key.

In this guide, we'll walk you through the process of calculating the number of chain links required for connecting two sprockets and demystify the complexities of chain assembly.

Understanding the Essentials

Chain Pitch and Sprocket CC:

Before delving into calculations, it's essential to note that chain pitch and the center distance (CC) of sprockets are measured in metric units (mm), not inches. Familiarize yourself with the metric equivalents for common inch measurements:

  • 06B - 3/8" = 9.5mm

  • 08B - 1/2" = 12.7mm

  • 10B - 5/8" = 15.87mm

  • Chain Pitch and CC: Ensure that the values are in metric units (mm).

  • Sprocket Pitch: Match the metric equivalent to the inch measurement.

Calculating Chain Length:

  1. Sprocket Teeth: Input the number of teeth for the smaller and larger sprockets.

  2. Chain Pitch: Select the appropriate metric chain pitch based on your sprocket size.

  3. Chain Length Calculation: The calculator will determine the total number of links required for your sprocket assembly.


Determining Lock Type:

Odd number indicates a Half Lock,

while an even number signifies a Full Lock.

Tips and Considerations: Precise Roller Pitch: In the realm of roller conveyors, especially when one sprocket is non-adjustable, precise roller pitch becomes imperative. This ensures optimal performance and prevents unwanted complications during operation.

In Closing: Navigating the intricacies of sprocket-driven conveyor assembly requires attention to detail and a precise approach. The calculator provided serves as a handy tool to streamline the process, offering quick insights into chain length and lock type.
