Explain difference between spring and ball plunger

Workpieces are frequently secured and positioned using plungers. They can be found in both machinery and furniture.

When a load is applied to a plunger, a ball or pin sinks into the plunger’s body. Whereas all plungers operate in the same way, there are various different types of plungers, the most popular of which being ball and spring plungers.

But what exactly is the difference between a spring and a ball plunger?

What Is a Spring Plunger and How Does It Work?

A spring plunger, often known as an SLD (spring-loaded device), is a mechanical plunger with spring as its distinguishing feature.

A coiled spring is contained within the body of a spring plunger. A hex socket, slotted drive, or top slot may be used to insert a spring plunger, relying on the kind.

Spring plungers, like some other kinds of plungers, come in a range of materials.

Spring plungers are frequently fabricated from stainless steel, which is a common material.

It’s durable and, more critically, corrosion-resistant. Spring plungers are also made in carbon steel, brass, and nylon, in addition to stainless steel.

Whatever the case may be, all spring plungers have a coiled spring within the body. When a spring plunger is loaded, it depresses while also providing its own reactive force.

What Is a Ball Plunger and How Does It Work?

An alternative to this type of mechanical plunger is a ball plunger.

The ball isn’t in a static state. Instead, it is housed in a shallow groove that allows it to move about. When a load is applied to the ball, it depresses. Ball plungers like this can be found in drawers, cabinets, doors, and other woodworking projects.

Despite the fact that ball plungers can handle pressures, they are usually designed for lower loads than spring plungers.

A ball plunger’s ball has a very shallow depth. To put it another way, it won’t go all the way inside the plunger’s body. Rather, it will stay largely shallow.

Ball and Spring Plunger Categorisation

  • Plungers of the ball and pin types can be categorized in a variety of ways. Size, insertion technique, type of material, and ultimate force are among these characteristics.
  • The plunger’s shape is determined by its form and structure. Ball plungers, knurled head plungers, and press-fit plungers are some examples.
  • The installation method refers to how the spring is inserted into its slot or hole. Slotted drive, hex socket, and top slot are examples of techniques (used in blind-hole applications).
  • The materials used to make the plunger are known as materials. Aluminum, steel, polymers, and stainless steel are examples of material types. Each has qualities and costs that are appropriate for various purposes.
  • The amount of force per unit area that the plunger is meant to generate is known as end force. There are designs for mild, medium, and high-end forces on several springs and ball-type plungers.

Criteria for Selection

The type of spring plunger to choose is entirely dependent on the application.

The shape, body material, plunger components, end force, and width of a design can all be customised.

They can also be manufactured retractable or with a thread locking feature.

Final Words:

So, this was all about spring and ball plungers. Depending on the kind of work, you can choose between the two
