Thanks for the suggestion, looks like it would do the job but I was hoping to find something with a flange and bolt holes to secure it to a metal plate.
Okay, thanks for the heads up. I think I should be okay as what I need it for is quite a low-pressure, low-velocity application.
I didn't mean bodger in that sense of the word, never heard that one! Done some woodworking in the past, but not that kind.
Quick question; does anyone know whether a linear bearing, such as the flanged unit with part number LMH16UU, will allow for a twisting motion of the shaft (roll), as well as longitudinal movement?
