iLearnAlignment: Computer-based, self-paced Precision Shaft Alignment training


Quick facts 

iLearnAlignment provides step by step training from the comfort of your workplace or home.  iLearnAlignment covers a quick introduction to shaft alignment, and a far more detailed tour through dial indicator alignment, laser alignment, soft foot correction and more.

The 3D animations ensure that the concepts are well understood, and the procedures will be remembered.

iLearnAlignment can be installed on a PC so that Internet access is not required, or it can be accessed online via this website so that installation is not required.  Larger organizations can license our LMS portal or iLearnAlignment can be installed in your Learning Management System.

Licensing: iLearnAlignment is licensed per-person.  Each person can access the training for six months.

Languages: English

NEW: We now also offer on-site and public training courses on shaft alignment!

iLearnAlignment [Introduction] - 6 month subscription 
iLearnAlignment [Master] - 6 month subscription 


iLearnAlignment is an interactive, computer-based training course for shaft alignment.  It will take you step by step through the principles behind shaft alignment, and teach you how to align shafts with dial indicators and laser alignment systems. 

Our interactive training, 3D movies, and excellent simulation program make iLearnAlignment a very effective training system.

Shaft alignment is a tough skill to master.  We firmly believe that a person should be trained in dial-indicator methods in order to be successful with laser alignment - but that choice is yours.

The iLearnAlignment [Intro] product provides an introduction to shaft alignment (see below).  It is intended for those who will not perform shaft alignment but who wish to understand it.

iLearnAlignment [Master] goes into far more detail:

  • Alignment math review,
  • Pre-alignment preparation,
  • Soft foot checks and correction,
  • Dial indicator operation,
  • Reverse-dial and rim-face methods,
  • Laser alignment operation,
  • Moving the machine,
  • Dynamic movement (& thermal growth),
  • Machine train alignment.

While our training covers all of the essential procedures, and is filled with valuable tips and tricks, one of the greatest benefits is that our training will help people understand misalignment.  We have developed over 50 3D animations that demonstrate procedures, explain how things work, and clarify confusing concepts. 

So many 3D animations

To help explain the many technical concepts and procedures, we have created over 50 3D movies/animations that clarify even the most complex issues. 

Laser alignment and dial indicator alignment

The training system also discusses laser alignment systems: how they work, their benefits, and how they are used.  We cover the methods used by all of the major laser alignment companies.

We also discuss the technology and methodology used by all of the leading laser-alignment systems.

iLearnAlignment [Intro] 

If you need an introduction to shaft alignment in order to understand the benefits and the procedures, then all you need is iLearnAlignment [Intro].  The training comprises 190 narrated slides filled with 3D animations.

Licensing options

iLearnAlignment is licensed on a per-person, time-limited basis.  By default a user may access the training for six months.  Only one person may access an account.  If additional people require training, then additional accounts may be purchased.


The training system can be installed on your computer.  The training system is easy to install and provides fast access to the content.

The user will have an account and will be given six months to complete the training.  The life of the system can be extended.  Additional licenses can be purchased and accessed via a single computer or via separate computers.


Each person is provided with a user account.  Only one person may use the account.

[These accounts are monitored for usage and access locations (via IP addresses).  If misuse is suspected the account will be closed and the user will be contacted.]

iLearn-online learning portal

We are able to establish a portal for your organization.  A special domain will be created for you, e.g. http://yourorganization.ilearn-online.com The portal can hold numerous accounts, and managers can track user's progress and quiz scores.  Pricing can be established in two ways:

1. We can pre-define a select number of user accounts.  Additional user accounts can be purchased.

2. You can create new accounts as required, and we will invoice you each quarter based on the number of new accounts created.

Learning management systems

The iLearnAlignment content can be added to your Learning Management System.  We offer pricing plans for a set number of users (which may be extended later) and for open systems, where we invoice each quarter based on the number of new users.  However we cannot offer this option unless we have access to the usage records of your LMS.

Computer requirements

Web-based and iLearn-online learning portal

Internet Explorer, Fire Fox and Safari are all supported.  You just need to have Java enabled and Flash installed and you will be good to go!


iLearnAlignment requires a computer with a CD drive a sound card and a resolution of 1024x768 or better.  The computer does not have to be powerful to run iLearnAlignment.

Learning management systems
