Abstract
Bearing removal is a common maintenance task in automotive, industrial and agricultural machinery. Conventional mechanical pullers rely on screw force and can cause uneven loading or component damage. A pneumatic alternative offers controllable force and reduced physical effort.
This project designs and fabricates a pneumatic bearing puller consisting of a robust mild-steel frame, a double-acting pneumatic cylinder, adjustable gripping jaws, solenoid or manual control valves and a pressure regulator. Compressed air drives the cylinder to pull the bearing smoothly from the shaft or housing.
It is an excellent final-year project for Mechanical and Mechatronics students, combining pneumatic circuit design, structural fabrication and practical workshop application.
