Roundness detection

Product Description

Bearing is a kind of high-precision mechanical parts, its main feature is that the geometric shape accuracy of bearing parts is very high. And because most of the bearings are circular motion, the roundness error of the ring raceway and rolling body becomes an important quality control index. Of course, other related dimensions also have high roundness error requirements (such as inner and outer diameter dimensions). The roundness error deviation will cause the bearing rotation accuracy index to increase (such as the radial runout index is out of tolerance), and will cause the bearing vibration index to become larger, thus directly affecting the normal use of the user.

The measurement method of bearing roundness error is clearly stipulated in the relevant national standards, and its index compliance (limit requirements) can be evaluated according to the contract drawings or technical requirements during inspection.
