Questions about this item
How do I press the Mirka AOS027 ball bearing onto the pump shaft without damaging the races?
Support the inner race on a sleeve that matches the shaft diameter and press evenly; pressing on the outer race pushes the load through the balls and brinells the tracks.
When should I replace the Mirka AOS027 bearing in my AP or AOS vacuum pump?
Replace it when vibration increases, the pump runs hotter than normal, or the bearing emits a continuous growl — all signs the grease has broken down or the races are pitted.
What is the first limit reached when the Mirka AOS027 bearing runs continuously under load?
The grease temperature limit is reached first; once the lubricant overheats it loses film strength and the bearing fails quickly.
