BE-FAQ - Bearing measurement marks

Let me explain why BE Bearings have marks on the surface.

Every BE Bearing is hand measured. The measurement process uses a data logging Mitutoyo drop indicator with a rounded roller bearing tip. The roller bearing tip is like a wheel that rolls over the surface of the bearing while it measures the bearing thickness. This process leaves a very small mark on the surface of the bearing. The marks that this process leaves are totally harmless, and you will never be able to fill them with your fingers or even measurement with another device.

As the shells are hand measured, they are sorted and placed in bins with 0.00005 inch differences. The measuring, sorting, and binning allows us to create perfectly matched sets of bearings for each customer. Once the bearings are sorted and binned, they are then used to create matched sets. Each
