What Is Indexing Plunger With Horizontal Mounting Flange
The Indexing Plunger with Horizontal Mounting Flange has become the preferred choice for many equipment manufacturers due to its convenient installation method and reliable structural performance.
What Is an Indexing Plunger with Horizontal Mounting Flange? Simply put, this is a positioning pin design featuring a horizontal mounting flange. Compared to traditional straight-mount positioning pins, this type incorporates an additional flat flange structure, enabling more secure installation on horizontal surfaces or side structures of mechanical equipment.
The advantages of this structure include:
- Enhanced overall stability through flange mounting;
- Adjustable mounting hole positions for easier alignment;
- Simplified maintenance and replacement.
- Adjustable mounting hole positions for easier alignment;
- Simplified maintenance and replacement.
This design is particularly suitable for equipment structures with limited space or requiring side-mounted fixation. Examples include automated conveyor lines, sliding rails, and adjustable mechanical platforms, where such horizontal flange-equipped positioning elements are commonly used to achieve repeatable, precise positioning.
Regarding materials, precision component manufacturers like Mocayo typically select stainless steel for primary structural parts—such as the locating pin body and pin head—to ensure wear resistance and corrosion protection. Handle sections, however, are often crafted from plastic. This choice offers comfortable grip, excellent insulation properties, and lighter weight for easier operation.

The Indexing Plunger with Horizontal Mounting Flange features a compact and scientifically designed structure, primarily composed of the following key components:
1.Plunger Body:
This serves as the main structural element, typically manufactured from high-strength stainless steel or carbon steel. Its function is to anchor the entire assembly and withstand radial and axial loads during operation.

2.Pin Head:
The pin head directly engages the locating hole to achieve precise positioning. The stainless steel construction effectively prevents corrosion and wear, ensuring long-term stable operation.

Working Principle: Precision & Convenience
After learning about the What Is Indexing Plunger With Horizontal Mounting Flange, understanding the working principle is the key to mastering the product's performance.
When the operator pulls the plastic handle, the pin is driven out of the locating hole, and the mechanism is now in an "unlocked" state, allowing the positioned part to move or rotate freely.
When the handle is released, the internal spring immediately pushes the pin back into position and reinserts it into the positioning hole, realizing automatic locking.
