Bridgeport Harig

As of January 1st Harig Products closed it’s Elgin location and is moving all parts to the Tru Tech Systems location in Mt Clemens, Michigan. I will continue to sell OEM parts and provide phone service for all the Harig Grinders from my home office located in Hampshire IL. Please contact me if you need parts, phone support, Bridgeport Harig machine parts, or any new and used machines.

As an authorized Harig consultant and technical support specialist, I have access to quality used and rebuilt Grinders, Mills, Lathes, and more. I can also refer you to experts who can rebuild your machine for 1/3 of a new Grinder price, with new machine tolerances and a 1-year guarantee.

If you have questions about rebuilding, contact Jim at 847-683-0476 or email me at for more information.

I am an Authorized Harig Consultant and Technical Support Specialist

I am now consulting from my home office and am looking forward to serving you, our valued customer. If you own a machine ten years or older you may contact us for parts and service. Many of our part numbers today don't match the part numbers you have in your manuals or your past notes, call and I will give you the retrofit part numbers for any future maintenance you may need. I can also suggest preventative maintenance and instruct you on the proper installation of your part, preventing costly damage to your machine.

President, Jim Seyller
