4 Common Mistakes in Bearing Installation

Improper operation during bearing installation often leads to premature damage or early failure of bearings, greatly increasing bearing costs. We have collected several common installation errors and shared them with everyone.

Walk within the inner circle

The fit between the shaft and the bearing inner hole is too loose (commonly known as "running the inner ring")

Due to the loose fit between the shaft and the inner hole selection, sliding occurs between the shaft and the inner hole surface. Sliding friction will cause heating, resulting in bearing damage due to heating.

4 Common Mistakes in Bearing Installation

Are there sliding marks between the shaft and the inner hole surface? Friction between the inner ring end face and the shaft shoulder generates heat and cracks

Due to the loose fit between the shell aperture and the bearing outer diameter, sliding occurs between their surfaces. Sliding friction will cause heating, leading to bearing damage due to overheating.
