Performance Solutions for Your Machines

Your machines are the backbone of your business – we make sure they perform at their best!

What we do.

Unisorb engineers machinery installation systems. Mounting, vibration isolation, grouting, anchoring, precision alignment. We figure out what your machine needs to hold tolerance under real operating conditions, then design the system to make it happen. One focus. Nothing else.

90 years of keeping machines where they belong.

Founded in 1935 as a subsidiary of The Felters Company, Unisorb started in shock and vibration control. Over nine decades, the focus has narrowed, not widened. While other companies expanded into general industrial supply, Unisorb went deeper into one discipline: machine installation engineering.

That focus produced the only engineering department in the category built exclusively for machine installation systems. An application engineering team on the front line of every project, supported by licensed P.E. staff when foundation design enters the picture. On-site project management. Construction-ready documentation. Grouting, anchoring, precision alignment, isolation, and foundation design.

Ninety years later, the question is still the same: will this machine hold position under real operating conditions? Everything we do answers it.
