[0002] A bearing is a component that plays a key role in mechanical transmission. It is usually composed of an inner ring, an outer ring, rolling elements and a cage. The main function of a bearing is to reduce friction between moving parts, withstand radial and axial loads, and make rotational motion smoother and more efficient. Different types of bearings are suitable for different working conditions and application scenarios.

[0003] In the prior art, after the bearing is produced, it needs to be polished and other processing operations, and it needs to be clamped. However, most of the current clamping devices can only clamp the bearing in the horizontal direction. The clamping device acts on the outer wall of the bearing, so that the outer wall of the bearing is blocked by the clamping device, which makes it inconvenient to process the outer wall of the bearing. For this reason, we propose a bearing processing clamping device. Utility Model Content
