Bearing, Thrust 51101

Needed to replace the thrust bearing on my X3 mill’s Y-axis screw, and this 51101 fit perfectly with no slop. The 12mm inner bore seated snugly, and the 9mm thickness matched the original exactly. Machine is running smooth again.

Slide right onto the X2.7’s Z-axis feed screw without any play. The 12mm inner diameter matched perfectly and the thrust surface is glass-smooth. Been cutting aluminum all week and the backlash hasn’t budged.

The 12mm inner diameter fit perfectly on my X2.7 mill's Z-axis, and the steel cage feels solid. Installed it in under ten minutes and the screw moves much smoother now.
