Description
Product Overview
The HARFINGTON Ball Spring Plunger set delivers ten precision‑engineered beads, each measuring 5mm in diameter and 6mm in length. Constructed from high‑grade 304 stainless steel, these pluggers combine excellent corrosion resistance with superior strength, ensuring they withstand the rigors of industrial and domestic environments. The surface finish is polished to a Ra 3.2 micron roughness, providing a smooth glide that reduces wear and extends service life. The elastic force of each plunger is calibrated at approximately 8 N, offering a reliable spring action that maintains consistent pressure without sagging. The design eliminates any step or ledge on the bead surface, allowing for seamless insertion and removal, which translates into faster assembly times and reduced risk of misalignment. Overall length is 7.2 mm, making the component compact enough to fit into tight mechanical assemblies while still delivering the necessary force for secure positioning.
Usage
These spring plungers are versatile components used across a broad spectrum of applications. In furniture manufacturing, they serve as reliable latch mechanisms for drawer fronts, cabinet doors, and sliding panels, providing a quiet, tactile click that signals a secure closure. In tool and fixture design, the pluggers act as quick‑release pins, allowing technicians to lock workpieces in place during machining, grinding, or assembly operations. Automation equipment benefits from the no‑step design, which enables rapid positioning of moving parts in robotic arms, conveyor systems, and pneumatic actuators. Because the pluggers are made of stainless steel, they are suitable for environments exposed to moisture, chemicals, or temperature fluctuations, such as food processing lines, laboratory benches, and outdoor installations. Installation is straightforward: the bead is pressed into a pre‑drilled hole using a simple hand tool, and the spring action automatically secures the component without the need for additional fasteners.
Why Choose Us
Choosing HARFINGTON means selecting a brand with a reputation for precision engineering and rigorous quality control. Each batch of spring plungers undergoes a multi‑stage inspection process, including dimensional verification, hardness testing, and corrosion resistance assessment, to guarantee that every bead meets the specified tolerances of ±0.05 mm in diameter and ±0.02 mm in length.

FAQ
What material is the ball plunger made from?
The plunger is fabricated from 304 stainless steel, which provides high corrosion resistance, strength, and heat tolerance, making it suitable for both indoor and outdoor applications.
Can the plunger be used in high‑temperature environments?
Yes. The 304 stainless steel composition retains its mechanical properties up to approximately 870 °F (465 °C), so it can be employed in most industrial temperature ranges without loss of performance.
How do I install the spring plunger?
First, drill a hole matching the 5 mm diameter specification. Then, using a small press tool or a pair of pliers, push the bead into the hole until it seats fully. The spring action will automatically lock the plunger in place.
What is the recommended maintenance schedule?
Inspect the plunger periodically for signs of wear or debris buildup. Clean the bead with a mild detergent and a soft brush if necessary. Replace any plunger that shows deformation or loss of spring force.
Is this product compatible with plastic housings?
Yes, the plunger can be used with compatible plastic or metal housings, provided the hole dimensions are accurate and the material can tolerate the 8 N insertion force without cracking.
