Testimonials

We used Servo Supplier to refurbish old drives and buy reconditioned parts. We received great and timely service at a fair price. I recommend them to anyone who has aging equipment and can't find support from their OEMs. Highly recommend.

Bostik Inc.

WE absolutely LOVE Servo Supplier. They are quick, efficient and friendly. Honest too, which is huge in our industry. We deal with many different companies, and these guys are tops in our humble opinion. There has never been an issue with delivery, no warranties, no hidden fees, no surprises. Just what you want in the manufacturing business. Smooth, and we love smooth.

Technomech Inc

First-time customer. The ordering process was completely seamless. The part that we ordered was at our business within 2 days. Which was excellent! We had a piece of equipment down for a little more than 48 hours. Could have been a lot longer had we purchased from one of our normal suppliers.

Steve T. from NF&M International

I found these guys online and needed a somewhat obscure part quickly, and they delivered! Very quick process from the time I requested a quote to the shipping of my items. Great work Servo Supplier team!

FlexPac

Servo Supplier is my go to place for obsolete parts. They always seem to find them and the price is usually good. Any time I have questions they respond very quickly and professionally. I highly recommend them!

Middlesex General Industries

They were very quick to get the drive we needed shipped out to us. They were also very quick to respond and help with some pictures of information on the unit we ordered to ensure we received the right part.

Justin Ball from Miba

Understood our situation, and worked to help us get it solved. Very responsive, and stepped out to keep me informed until the product arrived. Exactly as described, and promised.

Brian Tomlin

This company was fantastic to work with! Very patient with us to make sure we were getting what we needed and extremely quick shipping. Would definitely purchase from them again and again!
