Ways to distinguish "KOYO imported bearing flexibility"

In practice production; we often need to test the rotational flexibility of the bearing; it is not easy to measure the radial clearance of KOYO bearings; because the measuring force will make the ferrule and roll body of KOYO imported bearings and their touch Elastic deformation occurs; the deformation is the multi-element that forms the measurement error; it is related to the measurement force, the touch condition and the orientation of the roll.
KOYO imported bearing rotation flexibility is usually viewed in a horizontal orientation; usually the inner ring is fixed (or hand-held inner ring); the outer ring is changed by hand; whether there is abnormal motion and blockage when the bearing rotates. Generally speaking; bearing rotation The duration of the time is long; the suspension is slow; the flexibility is good. On the contrary; the rotation time is short; the suspension is abrupt; the flexibility is not good. The bearing layout and scale are different; the rotation flexibility should also have different requirements. For example, single row radial ball bearings, single row radial thrust ball bearings; because of the touch area between the roll and the ferrule. 庑KOYO imported bearings are more compact; and double row radial spherical bearings and thrust roller bearings; Because the rolling contact area of ​​the rolling body and the raceway is larger; the weight of the outer ring is more than that of the 外 保 保 浼 浼 浼 浼 浼 ǜ ǜ ǜ ǜ ǜ ǜ ǜ ǜ 淝峥 淝峥 淝峥 淝峥 淝峥 淝峥 淝峥 淝峥 淝峥 淝峥 淝峥 淝峥 淝峥 淝峥For very large bearings; when rotating it; there should be no jamming; and the rotation is usually not viewed.
For bearings with tapered bores; the following methods can be used to make up for the rotational flexibility of KOYO bearings; the specific operation is as follows:
Press the tapered bore bearing into the mandrel until a certain radial preload is applied; under this preload; when a ferrule is changed, the tumbling body should be converted. If the tumbling body is sliding instead of changing; There are too many shortcomings in the shape of the ferrule, or the scale of the tumbling body is not uniform; the rotation flexibility of the bearing is also poor.
