trunnion installed in a Chinese bandsaw
The trunnion received was a better quality than the original (thicker and stronger).I had to file a little bit on the part that goes inside, so it can slide from side to side. Other than that my new one was identical as the old one . Very happy with the part and specially the price.

faster fix
Tried to order from another business. 4 weeks later I thought "I had used -EReplacements before, let's see what they could do"?
A week later the part was here. Thanks.

A smidgen thicker than original
I had to grind down the nut that slides inside to fit but it’s still a good part. My trunnions broke from turning the bandsaw using the table. That’s definitely a no no. Shipping was fast. Thanks

Extremely Fast Turnaround.
This trunnion was a perfect match for my PC bandsaw. I was extremely happy with this purchase, because the price was great, and shipping costs were very modest, especially considering how fast it arrived. When these guys say “ships within one business day” they really mean it.

Worked great!
Thank u for getting this part to me.
It did take a long time to get it, but I was informed that this item was out of stock at the time I placed my order. I was a little concerned as my credit card was billed weeks before I received the part. I was told that this was normal procedure with your business.
However, it was just what I needed and I am so proud to have it. Thank u.

My repair was similar to other repairs listed before, but I did have to modify the trunnion shoes/clamps that fit inside the trunnions themselves. The aluminum casting on the replacement parts was thicker than on the OEM parts, so I had to use my oscillating belt sander to take off extra material on the sides of the shoes/clamps so that they could more easily slide around in the trunnions. After that it was a relatively easy repair.

Severely damaged bandsaw with missing parts

I bought a bandsaw that was damaged and missing parts. Everything between the table and the saw frame was missing. These parts were ordered from eReplacementParts and received quickly, including the trunnions which i had been told were on backorder until at least September. Installation was pretty straightforward, bolt the mount to the frame, bolt the trunnions to the table, then install the table assembly to the mount using the special bolts supplied. Although i'm still looking for a couple of unique parts (handles, etc), i now have a useable 14" bandsaw.

In moving bandsaw the shoe inside of trunnion pulled through and broke both trunnions. I replaced with new parts but had to grind down both sides of shoes so they would fit into the new part.
