I used these followers to follow the track of my chair life. My old wheel bearings wore out after 105500 thrips either up or down the stairs in on year. We will see how these do.

The cam followers were described as being made of stainless steel. However, as you can see from the photo, they are not. All four rollers have rusted although the runners are brass.Absolute rubbish!
