A shaft press is a small press used for precision work and installing bearings, classified by the load it can place on an object. It is used in machine shops for installing pistons, gudgeon pins, universal joints, and wheel bearings. The arbor press is a hand-operated hydraulic ram used for pressing parts into place. Accurate alignment is critical, and applying maximum pressure and heat sparingly can release stubborn parts. The arbor press is a useful tool for detailed work in a home workshop or garage.
A shaft press is a small press typically used for precision work and for installing bearings and bearing raceways. While similar to heavy-duty presses, the shaft press is usually classified by the load it can place on an object. A 2-ton shaft press can exert 2 tons (1.814 kg) of force or pressure on its work piece.
Many machine shops use the shaft press to install pistons and gudgeon pins into connecting rods. The precise operation of the small press makes it ideal for precision work. Replacing the universal joint and installing it into a drive shaft and pressing wheel bearings into axle housings are also jobs reserved for the shaft press operator.
The arbor press typically uses a hand-operated hydraulic ram mounted within a steel frame. The piston is pumped up and the press applies pressure against a part. The parts are held in place against the press frame so they don’t move. As the pressure increases, the part eventually succumbs to the pressure and breaks free from its mounting position. The new part is pressed into place in the same way.
It is critical to align all parts accurately when using a shaft press. The forces exerted on the workpiece are capable of destroying an object that may be only slightly out of alignment. When installing the press, special attention must be paid to the details. It is never wise to rush a print application.
Often a piece refuses to loosen when pressure is applied. In these cases it is often the practice to apply the maximum amount of pressure to a piece and let it rest under the pressure for a short time. The pressure often gets the better of the stubborn part and it will break free. It is rarely necessary to apply heat to an item in a press, but when heat is needed to release an item, use it sparingly. The force exerted on the object together with the applied heat could cause the part to fly out of its mounted position and cause injury or job site damage.
The arbor press is a handy tool that saves many hours of pounding and hammering with a hammer on many jobs. The precise action of the small press allows you to carry out detailed and intricate work in the home workshop or garage. By doing some of the necessary repairs at home, a handyman can save resources.
