The Reasons for IKO Bearings Fracture Failure

The main reason of IKO bearing fracture failure is defect and overload the two factors. When the external load exceeds the limit strength of materials and then causes parts breakage, this is called overload fracture.Overload is mainly caused by sudden failure or improper installation of the host. IKO needle bearings parts micro crack, shrinkage, bubbles, large foreign materials, overheated structure and local burn and so on defects will be fractured caused by overload shock or violent vibration, this is called defect fracture.

When IKO bearings in working, due to the external or internal factors, the original clearance changed, accuracy reduced, and even caused" seizure", this's called the clearance changes lost.The external factors such as the amount of surplus is too large, the installation is not in place, the expansion caused by temperature rise , instantaneous overload and etc; the intrinsic factors such as residual austenite and residual stress is in unstable state and so on, such are the main reasons of causing clearance change failure.
