The most effective type of puller for removing inner rings of bearings is the three-jaw puller. This tool is specifically designed with three adjustable arms that can grip the inner ring securely, providing a more balanced and even force during the removal process. Because the three jaws can wrap around the diameter of the inner ring, they minimize the risk of slippage and provide a solid grip, enabling efficient and effective extraction.

In contrast, other types of pullers may not offer the same level of stability or support. A single-jaw puller, while useful for certain applications, typically cannot provide adequate grip around a circular inner ring since it only has one point of contact. A two-jaw puller, although more stable than a single-jaw puller, still may struggle with evenly distributing force on the inner ring, leading to potential damage or incomplete removal. A hydraulic puller, while powerful and often effective for large, rusted, or stubborn components, may not always be necessary for bearing inner rings, and its design may complicate the task in tighter spaces where a three-jaw puller excels.

Overall, the three-jaw puller’s design allows for a more secure grip and application of force directly on the inner ring, making
