Most of the current pressing devices do not have a clamping mechanism when in use, so it is not convenient to align the bearing when the sleeve presses the bearing, and it is not suitable for the installation of bearings of different sizes. Most of the existing ones require manual pressing of the sleeve, which is inefficient. Therefore, a bearing self-positioning installation pressing device is proposed. Utility Model Content
