How do you translate "misalignment spacers"? I'm looking for the word for "misalignment spacers", which are mechanical parts for use with Heim joints (鱼眼轴承). Anyone know what they're called in China? Here's a photo. Misalignment spacers are the pair on the right. The left is just a Heim joint. Any mechanics around here?
"High misalignment aluminum spacer" is named 高偏差铝垫片.

So, "misalignment spacer" is 偏差垫片.
