Good value
Solid quality bushings. The fit was slightly tighter than expected but manageable with a press.

Great fit for robotic arm
Used these on a 28mm shaft for a joint mechanism. The self-lubricating feature works well and no grease is needed.

Solid build
Works well for low speed applications. Wish it came in larger bulk packs for industrial use.
