NA209 Economy Radial Insert Ball Bearing (45mm shaft)

$51.96Per: EACH



UG-Series Ball Bearings (Also known as NA or UEL or EW series) feature a locking collar which has a counterbored recess made purposely eccentric to the collar bore. When assembled on the shaft, this eccentric recess engages, or mates, with an eccentric cam end of a bearing’s inner ring. The collar is engaged on the inner cam of the bearing. This assembly grips the shaft tightly with a positive binding action that increases with use. No adjustments of any kind are necessary. The collar setscrew provides supplementary locking.
