Why Every Tutor Fails with Bearing Pullers – Absolute Truth Revealed When it comes to machine maintenance, bearing pullers are essential tools for safely removing or installing cylindrical bearings. Yet despite their importance, many tutors—whether instructors, trainers, or self-proclaimed experts—fail spectacularly by relying solely on standard or improper bearing puller techniques. The result? Costly damage, safety hazards, and frustrated earners. In this article, we uncover the absolute truth no one wants to talk about: why every tutor fails with bearing pullers—and how to break the cycle. ### The Myth That Hurts: Bearings Are Not One-Size-Fits-All Most novice instructors teach bearing removal using a single mechanical approach, often equating puller use with brute force. This misconception is dangerous. Bearings come in various sizes, designs, and materials, and improper puller application can crack raceways, damage seals, or bend shifting components. Tutors ignore these nuances, leading learners to believe that “any puller works on any bearing”—a fatal oversimplification.
