Bearing, Thrust 51106

The 30mm inner diameter seated perfectly on my mill spindle without any play. It runs smooth and quiet even under load during heavy cuts.

It’s 11mm thick and fits the X3 mill spindle perfectly — no grinding or wobble when I spun it up. Arrived clean and well-packed, and the single-direction design does exactly what it should for the thrust load.

The 51106 dimensions matched the spindle housing on my X3 mill exactly, no shimming needed. The single-direction design handles the thrust load cleanly during heavy cuts, and it spins smooth right out of the box.
