I spoke with my contact at Ultra-Fab about the grease fitting in the bolt on the Steel Micro-Roller # UF48-979021. She said that the design was changed a little over a year ago, changing the fitting from a press-in fitting to a screw-in fitting.

My contact confirmed that they do not typically have problems with the bolts or other components of the # UR48-979021.
