Review on Uxcell Bearing Inside Economy Lubricating Power Transmission Products by David Robinson

Ball well finished, good thread. However, the bushings that hold the bullet don't fit completely into the body. Instead, bushings are thin rings pressed on each side. A couple of these bushings on the blocks I received were loose enough to rotate in the body. I suspect that these sockets could be squeezed out of the body, especially under heavy loads. They are inexpensive and can be useful for non-critical, light-load applications where failure would not cause harm.
